Accounting Policies [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	Basis of Presentation. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the instructions for Form 10-Q and, accordingly, do not include all information and footnotes required by generally accepted accounting principles for complete financial statements. These financial statements should be read in conjunction with the consolidated financial statements and footnotes included in our Annual Report on Form 10-K for the fiscal year ended March 29, 2020 , previously filed with the Securities and Exchange Commission (“SEC”). In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments necessary to present fairly our financial position and the results of our operations and cash flows for the periods presented. All adjustments made to the interim condensed consolidated financial statements were of a normal recurring nature. All significant intercompany accounts and transactions have been eliminated in consolidation. The results of operations for the six months ended September 27, 2020 are not necessarily indicative of the results that may be expected for the full year. References to fiscal 2019 refer to the fiscal year ended March 31, 2019, references to fiscal 2020 refer to the fiscal year ended March 29, 2020 and references to fiscal 2021 refer to the fiscal year ending March 28, 2021. Use of Estimates. The preparation of condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, particularly receivables, inventories, property, plant and equipment, right-of-use assets, goodwill, intangibles, accrued expenses, short-term and long-term lease liability, income taxes and related accounts and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Accounting Policies. The accounting policies we follow are set forth in Note 1 – Nature of Business and Significant Accounting Policies to our consolidated financial statements in our Annual Report on Form 10-K for the fiscal year ended March 29, 2020 , previously filed with the SEC. There has been no significant change in our accounting policies since the end of fiscal 2020. Recently Adopted Accounting Pronouncements On March 30, 2020, we adopted Accounting Standards Update (“ASU”) 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments . The amendments in this update replaced the incurred loss impairment methodology in previous GAAP with a methodology that reflects expected credit losses on instruments within its scope, including trade receivables. This update is intended to provide financial statement users with more decision-useful information about the expected credit losses. Our adoption of this ASU impacted our method for calculating and estimating our allowance for doubtful accounts but did not have a material impact to our financial position or results of operations.

Business Combinations [Abstract]
Business Combination Disclosure	Business Combinations Acquisition of American Development Corporation of Tennessee, Inc. : On July 28, 2020, we acquired substantially all the assets of American Development Corporation of Tennessee, Inc. (“ADC”) under the terms of an asset purchase agreement with ADC and its shareholders. We paid $25 million for the acquisition, using funds available on our revolver to fund the acquisition. ADC is a water treatment chemical distribution company operating primarily in Tennessee, Georgia and Kentucky. The results of operations since the acquisition date, and the assets, including the goodwill associated with this acquisition, are included in our Water Treatment segment. Costs associated with this transaction were not material and were expensed as incurred. The acquisition has been accounted for under the acquisition method of accounting, under which the total purchase price is allocated to the net tangible and intangible assets and liabilities of ADC acquired in connection with the acquisition based on their estimated fair values. We estimated the fair values of the assets acquired and liabilities assumed using a discounted cash flow analysis (income approach). Of the $25 million purchase price, we allocated $13.3 million to finite-lived intangible assets, primarily customer relationships to be amortized over 17 years, $1.6 million to property, plant and equipment, and $0.9 million to net working capital. The residual amount of $9.2 million was allocated to goodwill. The goodwill recognized as a result of this acquisition is primarily attributable to strategic and synergistic benefits, as well as the assembled workforce. Such goodwill is expected to be deductible for tax purposes. The purchase price allocation is preliminary and subject to adjustment within the first 12 months following the acquisition.

Disaggregation of Revenue [Abstract]
Revenue from Contract with Customer	Revenue Our revenue arrangements generally consist of a single performance obligation to transfer promised goods or services. We disaggregate revenues from contracts with customers by operating segments as well as types of products sold. Reporting by operating segment is pertinent to understanding our revenues, as it aligns to how we review the financial performance of our operations. Types of products sold within each operating segment help us to further evaluate the financial performance of our segments. The following tables disaggregate external customer net sales by major revenue stream for the three and six months ended September 27, 2020 and September 29, 2019: Three months ended September 27, 2020 (In thousands) Industrial Water Health and Total Bulk / Distributed specialty products (1) $ 9,313 $ 4,358 $ 28,953 $ 42,624 Manufactured, blended or repackaged products (2) 51,155 44,838 8,133 104,126 Other 703 344 4 1,051 Total external customer sales $ 61,171 $ 49,540 $ 37,090 $ 147,801 Three months ended September 29, 2019 (In thousands) Industrial Water Health and Total Bulk / Distributed specialty products (1) $ 11,599 $ 4,971 $ 22,892 $ 39,462 Manufactured, blended or repackaged products (2) 55,607 40,487 3,189 99,283 Other 884 410 4 1,298 Total external customer sales $ 68,090 $ 45,868 $ 26,085 $ 140,043 Six months ended September 27, 2020 (In thousands) Industrial Water Health and Total Bulk / Distributed specialty products (1) $ 18,137 $ 8,233 $ 54,898 $ 81,268 Manufactured, blended or repackaged products (2) 112,997 80,344 14,231 207,572 Other 1,539 677 (83) 2,133 Total external customer sales $ 132,673 $ 89,254 $ 69,046 $ 290,973 Six months ended September 29, 2019 (In thousands) Industrial Water Health and Total Bulk / Distributed specialty products (1) $ 26,612 $ 9,679 $ 47,495 $ 83,786 Manufactured, blended or repackaged products (2) 115,078 78,637 7,333 201,048 Other 1,725 804 16 2,545 Total external customer sales $ 143,415 $ 89,120 $ 54,844 $ 287,379 (1) For our Industrial and Water Treatment segments, this line includes our bulk products that we do not modify in any way, but receive, store, and ship from our facilities, or direct ship to our customers in large quantities. For our Health and Nutrition segment, this line includes our non-manufactured distributed specialty products, which may be sold out of one of our facilities or direct shipped to our customers. (2) For our Industrial and Water Treatment segments, this line includes our non-bulk specialty products that we either manufacture, blend, repackage, resell in their original form, or direct ship to our customers in smaller quantities, and services we provide for our customers. For our Health and Nutrition segment, this line includes products manufactured, processed or repackaged in our facility and/or with our equipment. Net sales include products and shipping charges, net of estimates for product returns and any related sales rebates. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring products. All revenue is recognized when we satisfy our performance obligations under the contract. Our criteria for recording revenue is consistent between our operating segments and types of products sold. We recognize revenue upon transfer of control of the promised products to the customer, with revenue recognized at the point in time the customer obtains control of the products. In

Earnings Per Share [Abstract]
Earnings per Share	Earnings per Share Basic earnings per share (“EPS”) is computed by dividing net earnings by the weighted-average number of common shares outstanding. Diluted EPS includes the dilutive impact of incremental shares assumed to be issued as performance units and restricted stock. Basic and diluted EPS were calculated using the following: Three Months Ended Six Months Ended September 27, 2020 September 29, 2019 September 27, 2020 September 29, 2019 Weighted-average common shares outstanding—basic 10,527,891 10,575,538 10,526,511 10,589,922 Dilutive impact of performance units and restricted stock 94,990 57,579 107,770 73,942 Weighted-average common shares outstanding—diluted 10,622,881 10,633,117 10,634,281 10,663,864 For each of the periods presented, there were no shares excluded from the calculation of weighted-average common shares for diluted EPS.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities Disclosure [Text Block]	Derivative Instruments We have an interest rate swap agreement to manage the risk associated with a portion of our variable-rate long-term debt. We do not utilize derivative instruments for speculative purposes. The interest rate swap involves the exchange of fixed-rate and variable-rate payments without the exchange of the underlying notional amount on which the interest payments are calculated. The $20 million swap agreement will terminate on December 23, 2020. We have designated this swap as a cash flow hedge and have determined that it qualifies for hedge accounting treatment. For so long as the hedge is effective, changes in fair value of the cash flow hedge are recorded in other comprehensive income (net of tax) until income or loss from the cash flows of the hedged item is realized. For the three and six months ended September 27, 2020, we recorded a nominal amount in other comprehensive income related to unrealized gains (net of tax) on the cash flow hedge described above. For the three months ended September 29, 2019, we recorded $0.1 million in other comprehensive loss related to unrealized losses (net of tax) on the cash flow hedge. For the six months ended September 29, 2019, we recorded $0.2 million in other comprehensive loss related to unrealized losses (net of tax) on the cash flow hedge. Included in other current liabilities on our condensed consolidated balance sheet was $0.1 million as of September 27, 2020 and March 29, 2020. Unrealized gains and losses will be reflected in net income when the related cash flows or hedged transactions occur and offset the related performance of the hedged item.

We classify the inputs used to measure fair value into the following hierarchy: Level 1: Quoted prices in active markets for identical assets or liabilities. Level 2: Quoted prices in active markets for similar assets or liabilities, or quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable or can be corroborated by observable market data for the asset or liability. Level 3: Unobservable inputs for the asset or liability that are supported by little or no market activity. These fair values are determined using pricing models for which the assumptions utilize management’s estimates or market participant assumptions. Assets and Liabilities Measured at Fair Value on a Recurring Basis. The fair value hierarchy requires the use of observable market data when available. In instances where inputs used to measure fair value fall into different levels of the fair value hierarchy, the fair value measurement has been determined based on the lowest level input that is significant to the fair value measurement in its entirety. Our assessment of the significance of a particular item to the fair value measurement in its entirety requires judgment, including the consideration of inputs specific to the asset or liability. Our financial assets that are measured at fair value on a recurring basis are an interest rate swap and assets held in a deferred compensation retirement plan. As of September 27, 2020 and March 29, 2020, the assets held in a deferred compensation retirement plan are classified as other long-term assets on our balance sheet, with the portion of the plan assets expected to be paid within twelve months classified as current assets and the interest rate swap is classified as other current liabilities on our balance sheet. The fair value of the interest rate swap is determined by the respective counterparties based on interest rate changes. Interest rate swaps are valued based on observable interest rate yield curves for similar instruments. The deferred compensation plan assets relate to contributions made to a non-qualified compensation plan on behalf of certain employees who are classified as “highly compensated employees” as determined by IRS guidelines. The assets are part of a rabbi trust and the funds are held in mutual funds. The fair value of the deferred compensation is based on the quoted market prices for the mutual funds at the end of the period. The following tables summarize the balances of assets and liabilities measured at fair value on a recurring basis as of September 27, 2020 and March 29, 2020. 0 (In thousands) September 27, 2020 March 29, 2020 Assets Deferred compensation plan assets Level 1 $ 5,573 $ 3,564 Liabilities Interest rate swap Level 2 $ 69 $ 108

Share-based Payment Arrangement [Abstract]
Share-Based Compensation	Share-Based Compensation Performance-Based Restricted Stock Units . Our Board of Directors (the “Board”) approved a performance-based equity compensation arrangement for our executive officers during the first quarters of each of fiscal 2021 and fiscal 2020. These performance-based arrangements provide for the grant of performance-based restricted stock units that represent a possible future issuance of restricted shares of our common stock based on a pre-tax income target for the applicable fiscal year. The actual number of restricted shares to be issued to each executive officer is determined when our final financial information becomes available after the applicable fiscal year and will be between zero shares and 62,385 shares in the aggregate for fiscal 2021. The restricted shares issued, if any, will fully vest approximately two years after the last day of the fiscal year on which the performance is based. We are recording the compensation expense for the outstanding performance share units and the converted restricted stock over the life of the awards. The following table represents the restricted stock activity for the six months ended September 27, 2020: Shares Weighted- Unvested at beginning of period 74,515 $ 34.27 Granted 64,813 37.37 Vested (5,263) 31.35 Forfeited or expired (14,505) 35.83 Unvested at end of period 119,560 $ 35.89 We recorded compensation expense related to performance share units and restricted stock of $0.5 million and $1.0 million for the three and six months ended September 27, 2020, respectively. We recorded compensation expense related to performance share units and restricted stock of $0.4 million and $0.8 million for the three and six months ended September 29, 2019, respectively. Substantially all of the compensation expense was recorded in selling, general and administrative expenses in the condensed consolidated statements of income. Restricted Stock Awards . As part of their retainers, each director who is not an executive officer receives an annual grant of restricted stock for their service on our Board. The restricted stock awards are expensed over the requisite vesting period, which is one year from the date of issuance, based on the market value on the date of grant. As of September 27, 2020, there were 5,874 shares of restricted stock with a grant date fair value of $51.06 outstanding under this program. Compensation expense for both the three months ended September 27, 2020 and September 29, 2019 related to restricted stock awards to the Board was $0.1 million. Compensation expense for both the six months ended September 27, 2020 and September 29, 2019 related to restricted stock awards to the Board was $0.2 million.

Segment Information	Segment Information We have three reportable segments: Industrial, Water Treatment, and Health and Nutrition. The accounting policies of the segments are the same as those described in the summary of significant accounting policies in our Annual Report on Form 10-K for the fiscal year ended March 29, 2020 . We evaluate performance based on profit or loss from operations before income taxes not including nonrecurring gains and losses. Reportable segments are defined primarily by product and type of customer. Segments are responsible for the sales, marketing and development of their products and services. Other than our Health and Nutrition segment, the segments do not have separate accounting, administration, customer service or purchasing functions. We allocate certain corporate expenses to our operating segments. There are no intersegment sales and no operating segments have been aggregated. No single customer’s revenues amounted to 10% or more of our total revenue. Sales are primarily within the United States and all assets are located within the United States.
