PENTAIR, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)

1.     The    accompanying    unaudited    condensed
consolidated financial statements have been prepared
in  accordance with instructions for Form 10-Q  and,
accordingly,  do  not  include all  information  and
footnotes  required by generally accepted accounting
principles  for  complete financial statements.   In
the   opinion   of   management,  all   adjustments,
consisting   only  of  normal  recurring   accruals,
considered  necessary for a fair  presentation  have
been included.

These statements should be read in conjunction  with
the  financial statements and footnotes included  in
the  Company's Annual Report on Form  10-K  for  the
year  ended December 31, 1998, previously filed with
the Commission.

The results of operations for the three months ended
March 27, 1999 are not necessarily indicative of the
operating results to be expected for the full year.

Income tax provisions for interim periods are  based
on the current best estimate of the effective annual
federal, state and foreign income tax rates.


2.  Subsequent Events

Web Tool & Manufacturing, Inc.
Pentair  significantly increased its penetration  of
fast-growing technology markets with the acquisition
of  WEB  Tool  & Manufacturing, Inc.  of  Elk  Grove
Village, Illinois which closed on April 2, 1999. WEB
designs,  manufactures, and  markets  custom  server
subracks   and   chassis  for  computer   technology
applications. The purchase price was not  disclosed,
but  Pentair  said  that WEB is  profitable  and  is
expected  to  be  accretive to Pentair  earnings  in
1999. The cash transaction was financed through bank
borrowings.

Essef Corporation
On  April  30, 1999, Pentair announced that  it  had
entered  into  a merger agreement to  acquire  Essef
Corporation  (Nasdaq: ESSF) of  Chardon,  Ohio,  for
$19.09 per share, payable in cash. Essef is a global
leader  in the manufacture of composite water tanks,
pumps,  filters,  and  other  water  equipment.  The
merger  excludes  Essef's  Anthony  &  Sylvan   pool
construction  business, which will be split  off  to
its  shareholders  at the time of  closing  of  this
acquisition.   The  cash  purchase  price  will   be
approximately $312 million. Pentair will also assume
approximately  $100 million of Essef debt.  Pentair,
which will finance the acquisition through available
lines  of  credit, expects Essef to be accretive  to
earnings over the first 12 months after acquisition.
The  merger  agreement, which was  approved  by  the
boards  of  both Pentair and Essef,  is  subject  to
Essef   shareholder  approval,  regulatory  approval
under  the Hart-Scott-Rodino Act, and completion  of
due  diligence by Pentair. Essef's annual sales, for
the  businesses  being acquired,  are  estimated  by
industry  analysts to be approximately $350 million.
Completion of the transaction is currently  targeted
for July 31, 1999.



3.  Earnings per common share
Basic earnings per common share is computed by
dividing net income, after deducting preferred stock
dividends, by the average common shares outstanding
during the period.

Diluted  earnings per common share  is  computed  by
dividing net income after adjusting the tax benefits
on  deductible ESOP dividends by the average  common
shares outstanding plus the incremental shares  that
would   have  been  outstanding  upon  the   assumed
exercise  of  dilutive stock options  and  upon  the
assumed  conversion of each series preferred  stock.
The  tax  benefits applicable to preferred dividends
paid  to  ESOPs are recorded in the following  ways:
for  allocated shares, they are credited  to  income
tax  expense and included in the earnings per  share
calculation;  for  unallocated  shares,   they   are
credited to retained earnings and excluded from  the
earnings per share calculation.

The  following  table reflects  the  calculation  of
basic and diluted earnings per share.

Subsequent to year-end, both Series 1988 and  Series
1990  preferred stock classes were redeemed and  all
shares were converted to common stock on January  4,
1999 and January 15, 1999, respectively.

On December 14, 1998, the Company announced that the
Pentair   board  had  authorized  the   Company   to
repurchase  on an annual basis up to 400,000  shares
of  Pentair  common stock.  Any purchases  would  be
made  periodically  in  the open  market,  by  block
purchases   or  private  transactions.   The   share
repurchase is intended to offset the dilution caused
by stock issuances under employee stock compensation
plans.   As  of  March  27, 1999,  the  Company  had
repurchased 95,500 shares under the authorization.

10. Reclassifications
Certain  reclassifications have been made  to  prior
years'  financial  statements  to  conform  to   the
current year presentation.

11. Accounting Developments
In  June  1998,  the Financial Accounting  Standards
Board   issued  Statement  of  Financial  Accounting
Standard   No.   133,  "Accounting  for   Derivative
Instruments  and Hedging Activities."   The  Company
must  adopt  this standard no later than January  1,
2000.  The Company is reviewing the requirements  of
this  standard,  which are quite complex.   Although
the  Company  expects that this  standard  will  not
materially affect its financial position and results
of  operations, it has not yet determined the impact
of this standard on its financial statements.

12. Special Restructuring Charge

In the first quarter of 1999, the Company recorded a
special restructuring charge of $38.0 million ($24.1
million  after-tax  or $.56 per  share).   As  shown
below, only $.4 million had been spent through March
27, 1999.

The  restructuring plan comprises  consolidation  of
certain   operations,   overhead   reductions,   and
outsourcing of specific product lines in each of the
Company's    three   business   segments.    Pentair
anticipates  a  net  reduction of approximately  700
jobs,  less  than  seven percent  of  the  company's
global   workforce.    Pentair's   Electrical    and
Electronic Enclosures Group already has initiated  a
major  overhead reduction in its European  enclosure
businesses  -- principally at the Schroff  operation
in   Straubenhardt,  Germany  --  and  manufacturing
rationalization  in  its North American  facilities.
This  Group will absorb $16.7 million of the charge,
with  anticipated savings of more than $4.0  million
in the remaining quarters of 1999 and more than $9.0
million   in  2000.   The  Professional  Tools   and
Equipment  Group will accelerate its  already-strong
performance     by    consolidating     distribution
operations, and by combining the headquarters of the
two  power  tool businesses, Delta and Porter-Cable.
In  the  service equipment businesses, products  are
being outsourced to offshore manufacturers, and  the
Jonesboro,  Arkansas,  manufacturing  operation   of
Lincoln  Automotive  will be  closed.  Restructuring
charges  of $16.8 million in this Group will deliver
anticipated  savings of more than $14.0  million  in
2000.   The Water and Fluid Technologies Group  will
reduce  the  workforce  at  its  Lincoln  Industrial
business  and  outsource some product manufacturing.
Approximately  50  percent  of  the  company's  U.S.
manufacturing facility will be closed. This  Group's
charge   will  be  $4.5  million,  with  anticipated
savings  of $0.4 million in late 1999 and more  than
$2.0 million in the year 2000.

The  components  of  the  restructuring  charge  and
related reserve balances remaining at March 27, 1999

RESULTS OF OPERATIONS

Consolidated Results.

Sales  and income in the first quarter of 1999  were
affected by our adoption of a standard "4-4-5  week"
quarter  for  Pentair reporting.  The first  quarter
ended  on March 27, 1999, with about 4 percent fewer
work days than the same period last year.  Pentair's
fiscal  year  will continue to end on  December  31.
Also,  operating  profits of the  segments  are  now
reported net of all their administrative and related
costs.  The prior year segment data was restated for
such reporting change.

Consolidated  net sales increased to $470.5  million
in 1999, representing a 1.2% increase over 1998.

Operating  income for 1999 includes a  restructuring
charge of $38.0 million ($24.1 million after-tax  or
$.56   per   share).   Excluding  the  restructuring
charge,   operating  income  increased   5.8%,   and
operating income as a percent of sales improved from
9.4%  to  9.9%.  Gross profit margins  increased  in
1999  to  31.8%  versus  31.1%  in  1998.   This  is
primarily  due  to internal cost reduction  efforts.
Selling,  general and administrative expense  (SG&A)
as  a percent of sales was 22.0% in 1999 as compared
to   21.7%  in  1998.   Net  income  excluding   the
restructuring  charge  increased  11.2%  over  first
quarter  1998.   Earnings per  share  excluding  the
restructuring charge was $.61, an increase of 13.0%.

The tax rate reduction to 36.5 percent is consistent
with  the  pattern of reductions effected  over  the
last two years.  It is anticipated that the tax rate
in  the  future  quarters of  1999  will  remain  at
approximately 36.5 percent, before the effect of new
acquisitions.   The  Essef  acquisition   will   add
approximately 1.4 percentage points to the full year
tax  rate,  due  to non-deductible  amortization  of
goodwill.

Professional Tools and Equipment Segment
First  quarter sales in the Professional  Tools  and
Equipment Group continued relatively strong,  driven
by  a  good  domestic economy and demand  for  newly
introduced products. A healthy economic outlook,  an
array  of  new  products, and continued distribution
expansion are expected to maintain high single-digit
sales growth in the second quarter of 1999.

Net  sales  increased  to $200.5  million  in  1999,
representing  a 6.6% increase over 1998.   Operating
income  excluding the restructuring charge increased
to  $22.2  million in 1999, up 16.0% over 1998,  and
operating income as a percent of sales improved from
10.2% to 11.1%.

Housing  starts  are  one  critical  factor  driving
performance in the tools businesses. Although starts
in  1999  are expected to be down slightly from  the
high  levels we experienced in 1998, retail  markets
will likely make up for slower construction markets.

Water and Fluid Technologies Segment
While   1998   was  a  year  of  consolidating   new
operations,  building efficiency,  and  outsourcing,
1999  will be a year for accelerating internal sales
growth.  Working  from the strong  base  established
last  year, a step up in top line growth is expected
through  entry  into  new  markets  and  accelerated
product development.

Net  sales  decreased  to $128.5  million  in  1999,
representing  a  5.2% decrease from 1998.  Operating
income  excluding the restructuring charge increased
to  $16.5  million in 1999, up 15.9% over 1998,  and
operating income as a percent of sales improved from
10.5% to 12.8%. Profits in the Group benefited  from
continued   productivity   improvements   and   cost
reductions, while the diminution in overall sales is
largely attributable to the deliberate reduction  in
the  sales  of  the  formerly unprofitable  Layne  &
Bowler  pump  line, begun in the second  quarter  of
1998.

First  quarter orders rose strongly in the pump  and
control  valve  businesses.  This  level  of   order
intake, driven in part by the recent introduction of
new products, is expected to generate second quarter
sales  growth in the mid-to-high single  digits  for
this segment.


Electrical and Electronic Enclosures Segment
In  the  Electrical and Electronic Enclosures Group,
reduced  capital  spending  in  key  industrial  and
electronic   markets,  and  continued  weakness   in
European   enclosure  markets,  resulted  in   first
quarter  sales below those of the same  period  last
year. Net sales decreased to $143.4 million in 1999,
representing a 1.4% decrease from 1998.

In  North American markets, a high level of  quoting
activity  late in the first quarter, much  of  which
originated   from  the  automotive   industry,   may
indicate  a  return  to  higher  industrial  capital
spending  for  the second quarter of 1999.  Although
European  markets  are expected to  continue  to  be
weak,  Pentair is improving its competitive position
by   implementing   overhead   reductions   in   its
underperforming German enclosures operation. Initial
savings  from  that reduction are  expected  in  the
third quarter of 1999.

Operating income excluding the restructuring  charge
decreased  to $12.4 million in 1999, down 9.7%  from
1998,  as  operating income as a  percent  of  sales
declined from 9.4% to 8.7%.

In  summary, the Company is encouraged  by  what  is
happening  in the North American market and  organic
sales are expected to grow in the mid-to-high single
digits  in  the second quarter of 1999.  In  Europe,
necessary  actions are being taken to structure  the
business appropriately for the conditions there, and
there  is  cautious optimism about sales  growth  in
that market.

SPECIAL RESTRUCTURING CHARGE
In the first quarter of 1999, the Company recorded a
special restructuring charge of $38.0 million ($24.1
million after-tax or $.56 per share).

The  restructuring plan comprises  consolidation  of
certain   operations,   overhead   reductions,   and
outsourcing of specific product lines in each of the
Company's    three   business   segments.    Pentair
anticipates  a  net  reduction of approximately  700
jobs,  less  than  seven percent  of  the  company's
global   workforce.    Pentair's   Electrical    and
Electronic Enclosures Group already has initiated  a
major  overhead reduction in its European  enclosure
businesses  -- principally at the Schroff  operation
in   Straubenhardt,  Germany  --  and  manufacturing
rationalization  in  its North American  facilities.
This  Group will absorb $16.7 million of the charge,
with  anticipated savings of more than $4.0  million
in the remaining quarters of 1999 and more than $9.0
million   in  2000.   The  Professional  Tools   and
Equipment  Group will accelerate its  already-strong
performance     by    consolidating     distribution
operations, and by combining the headquarters of the
two  power  tool businesses, Delta and Porter-Cable.
In  the  service equipment businesses, products  are
being outsourced to offshore manufacturers, and  the
Jonesboro,  Arkansas,  manufacturing  operation   of
Lincoln  Automotive  will be  closed.  Restructuring
charges  of $16.8 million in this Group will deliver
anticipated  savings of more than $14.0  million  in
2000.  The  Water and Fluid Technologies Group  will
reduce  the  workforce  at  its  Lincoln  Industrial
business  and  outsource some product manufacturing.
Approximately   50   percent   of   Lincoln's   U.S.
manufacturing facility will be closed.  This Group's
charge   will  be  $4.5  million,  with  anticipated
savings  of $0.4 million in late 1999 and more  than
$2.0 million in the year 2000.

The  components  of  the  restructuring  charge  and
related reserve balances remaining at March 27, 1999
were (in millions):

Remaining Reserve           $27.1       $7.0        $3.5    $37.6

LIQUIDITY AND CAPITAL RESOURCES
Cash flow from operating activities was negative
$24.2 million in 1999 compared to negative $49.4
million in 1998.  The Company believes that cash
flow from operations will continue to exceed its
needs for capital programs, smaller acquisitions and
dividends during the year.

Capital  expenditures  were  $7.4  million  in  1999
compared to $4.6 million in 1998. The Company had  a
negative  free  cash flow of $31.6 million  in  1999
compared to a negative $54.0 million in 1998.   Free
cash  flow,  a measure of the internal financing  of
operational  cash  needs, is defined  as  cash  from
operations less capital expenditures. The Company is
targeting  continued growth in free cash flow  as  a
percent of sales through improved profitability  and
working  capital  ratios.  Historically,  free  cash
flow is negative during the first few months of each
fiscal year and positive thereafter.

Borrowings in the first quarter of 1999 financed
operating needs and capital expenditures. The
percentage of long-term debt to total capital was
31% at March 27, 1999 compared to 29% at December
31, 1998.  The Company has sufficient financing
capacity to continue its current acquisition program
and to support its ongoing stock repurchase program.
The stock repurchase is intended to offset the
dilution caused by stock issuances under employee
stock compensation plans.  Significant acquisitions
(above approximately $250 million), such as Essef,
require increased credit facilities.  The Company
believes it can obtain adequate financing for
acquisitions.



OUTLOOK

While  the outlook for each of its segments in  1999
is encouraging, Pentair believes it must improve its
management  of  total capital and  thereby  increase
free cash flow.

Pentair's top line growth in the coming months will
be driven by new product introductions in the tools
and water businesses, and expanded distribution and
improved productivity in the enclosures businesses.
Improved order levels and stronger backlogs in our
tool and water segments, combined with several
growth initiatives in place across the organization,
should accelerate revenues in the second quarter and
beyond.  Meanwhile, the benefits of the $60 million
cost savings project and our restructuring
activities will reinforce the profitability of all
the operating groups.

In   addition,  Pentair  continues   to   look   for
synergistic  acquisitions in each  of  its  business
segments,  in  line with its pattern over  the  past
three   years.   Pentair  will  continue  to  pursue
complementary  acquisitions  to  fold  into  current
operations,  but will also carefully  review  larger
targets which would significantly expand its current
segments.  Other acquisitions are possible, but only
if they present Pentair extraordinary opportunities.

Acquisition and internal growth initiatives, coupled
with the savings anticipated from our cost-reduction
activities, are expected to generate consistent  and
attractive results for Pentair shareholders in  1999
and beyond.


YEAR 2000

Background
The Year 2000 issue is the result of computer
programs and embedded computer chips originally
having been designed and developed using two digits
rather than four digits to define the applicable
year.  Any of the Company's internal use computer
programs and hardware as well as its products that
are date sensitive may recognize a date using "00"
as the Year 1900 rather than the Year 2000.  This
could result in a system failure or miscalculations
causing disruptions of operations, including, among
other things, a temporary inability to process
transactions or engage in normal business activities
for both the Company and its customers who rely on
its products.

State of Readiness
The Company's businesses  have had "Y2K Project"
programs in place since as long ago as 1995 to
address Year 2000 problems in critical business
areas for information management systems, non-
information systems with embedded technology,
suppliers and customers. The Company has largely
completed its review and compliance planning for its
critical information systems (IS).  Certain of the
Company's larger businesses have completed the
implementation of required actions for compliance;
the balance of the business units are in the process
of implementation.  In many cases, implementation
includes installation of new Enterprise Resource
Planning ("ERP") systems designed to enable these
businesses to operate more efficiently and to
provide better management reporting.  Pentair
anticipates that implementation and testing phases
will be substantially complete throughout the
company by the third quarter of 1999.

The Company is also in the process of reviewing and
replacing, where necessary, its other automated
communications and manufacturing systems.  The
Company estimates that it will complete this phase
by the second quarter of 1999.

None of the Company's products are believed to be
date dependent.

The Company has close working relationships with a
large number of suppliers and customers.  These
include, among others, utility and telecommunication
providers, raw materials and components suppliers,
and financial institutions, managed care
organizations and large retail establishments.  The
Company has been reviewing, and continues to review,
with its critical suppliers and major customers the
status of their Year 2000 readiness. The Company's
business units have established plans for ongoing
monitoring of suppliers during 1999.

Costs to Address the Year 2000 Issue
As a result of the numerous different IS systems
used by businesses that the Company has acquired in
recent years and also as a result of changing
business requirements, the Company has an ongoing
development plan with scheduled replacements of
hardware and software occurring in 1999 throughout
the organization.  Year 2000 compliance is a by-
product of our development plan.

The estimated cost associated with the total IS
development plan over the five-year period from 1995
to 1999 is anticipated to be approximately $55
million, which is approximately 80% complete.  The
estimated cost specifically attributable to Year
2000 compliance, apart from other IS development
activities, amounts to approximately $10 million, of
which $8 million had been spent through December 31,
1998.  Pentair has not deferred any significant IS
projects as a result of the implementation of the
Y2K Project.

Risks Represented by the Year 2000 Issue
Pentair believes that completed and planned
modifications and conversions of its internal
systems and equipment will allow it to be Year 2000
compliant in a timely manner.  However, there can be
no assurance that the Company's systems or
equipment, nor those of third parties on which
Pentair relies, will be Year 2000 compliant , in all
material respects, in a timely manner.  Nor can
Pentair give any assurance that its own or third
parties' contingency plans will mitigate the effects
of any noncompliance.  Pentair believes that non-
compliance with Year 2000 issues would likely result
in some reduction of the Company's operations for
the first part of the year 2000, which could have a
material adverse effect on the Company's businesses
or their financial condition.  Based on its
assessments to date, Pentair believes it will not
experience any material disruption as a result of
Y2K issues in internal manufacturing processes,
information processing, interfacing with major
customers or processing orders and billing.
However, if critical utility service providers
experience difficulties, which affect Pentair, or
its business units, a shutdown of some or all
operations at individual facilities could occur.
Pentair is developing contingency plans to provide
for continuity of processing (in the event of a Y2K
disruption) which will be based on the outcome of
its Y2K compliance reviews and the results of third
party verification efforts.  Assuming no major
disruption in service from utility companies or
similar critical third-party providers, Pentair
believes that it will be able to manage its Year
2000 transition without material effect on Pentair's
results of operations or financial condition.

The most reasonably likely worst case scenario of
failure by Pentair or its suppliers or customers to
resolve Year 2000 issues would be a temporary
slowdown or cessation of manufacturing operations at
one or more of Pentair's facilities, and/or a
temporary inability on the part of Pentair to timely
process orders and to deliver finished products to
customers.  Delays in meeting customer orders would
reduce or delay sales and affect the timing of
billings to and payments received from customers and
could result in complaints, charges or claims, or
temporarily increasing working capital.

Contingency Plans
Pentair's businesses are in the process of
developing Year 2000 contingency plans, based on
their review of their internal and external
compliance progress.  A full review will be done
following the end of the second quarter of 1999 to
assess Pentair's vulnerability to internal non-
compliance and potential third-party failures and
actions which can be taken to reduce unfavorable
impacts.  Possible plans may include arranging
alternative or additional suppliers and service
providers, increasing inventory levels, providing
additional back-up systems and replacing or
upgrading equipment and software.

but are not limited to, 1) general economic
conditions, such as the rate of economic growth in
the Company's principal geographic markets or
fluctuations in exchange rates; 2) industry
conditions, such as the strength of product demand,
the intensity of competition, pricing pressures, the
acceptability of new product introductions, the
introduction of new products by competitors, changes
in technology or the ability of the Company to
source components from third parties without
interruption and at reasonable prices and the
financial condition of the Company's customers; 3)
operating factors, such as continued improvement in
manufacturing activities and the achievement of
related efficiencies therein, and inventory risks
due to shifts in market demand; and, 4) the
expectations, uncertainties, costs and risks
associated with Year 2000 issues, such as the

forward-looking statements in order to reflect
events or circumstances that may arise after the
date hereof.  Readers are urged to carefully review

ITEM 5 - Other Information
On  April  30, 1999, Pentair announced that  it  had
entered  into  a merger agreement to  acquire  Essef
Corporation  (Nasdaq: ESSF) of  Chardon,  Ohio,  for
$19.09 per share, payable in cash. Essef is a global
leader  in the manufacture of composite water tanks,
pumps, filters, and other water equipment. The  cash
purchase  price will be approximately $312  million.
Pentair  will also assume approximately $100 million
of  Essef  debt.  Pentair, which  will  finance  the
acquisition  through  available  lines  of   credit,
expects  Essef to be accretive to earnings over  the
first   12  months  after  acquisition.  The  merger
agreement, which was approved by the boards of  both
Pentair  and  Essef, is subject to Essef shareholder
approval,  regulatory approval under the Hart-Scott-
Rodino  Act,  and  completion of  due  diligence  by
Pentair.   Essef's  1999  sales  are  estimated   by
industry  analysts to be approximately $350 million,
exclusive  of its Anthony & Sylvan pool construction
business,  which will be split-off by Essef  to  its
current   shareholders  at  the   closing   of   the
acquisition.   Completion  of  the  transaction   is
