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 31, 2024 , 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 29, 2024 are not necessarily indicative of the results that may be expected for the full year. References to fiscal 2024 refer to the fiscal year ended March 31, 2024 and references to fiscal 2025 refer to the fiscal year ending March 30, 2025. 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 31, 2024 , previously filed with the SEC. There has been no significant change in our accounting policies since the end of fiscal 2024. Recently Issued Accounting Pronouncements Income Taxes (Topic 740): Improvements to Income Tax Disclosures (ASU No.2023-09) In December 2023, the Financial Accounting Standards Board ("FASB") issued accounting standards update No. 2023-09 to enhance the transparency and decision-usefulness of income tax disclosures and to provide information to better assess how an entity's operations and related tax risks and tax planning and operational opportunities affect its tax rate and prospects for future cash flows. For public business entities, the amendments in this update are effective for annual periods beginning after December 15, 2024. We are in the process of evaluating the impact of this standard on the disclosures in our financial statements. Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (ASU 2023-07) In November 2023, the FASB issued accounting standards update No. 2023-07 to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The update requires public entities to disclose, on an annual and interim basis, significant segment expenses that are regularly provided to the chief operating decision maker ("CODM"), the title and position of the CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources. The amendments in this update are effective for public entities in fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024 and are to be applied retrospectively to all prior periods presented in the financial statements. Early adoption is permitted. We are in the process of evaluating the impact of this standard on the disclosures in our financial statements.

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.

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 29, 2024 October 01, 2023 September 29, 2024 October 01, 2023 Weighted-average common shares outstanding—basic 20,757,397 20,903,690 20,786,938 20,905,707 Dilutive impact of performance units and restricted stock 103,021 122,738 111,703 128,446 Weighted-average common shares outstanding—diluted 20,860,418 21,026,428 20,898,641 21,034,153 For each of the periods presented, there were no shares excluded from the calculation of weighted-average common shares for diluted EPS.

Fair Value Disclosures [Abstract]
Fair Value Measurement and Measurement Inputs, Recurring and Nonrecurring [Text Block]	Fair Value Measurements Our financial assets and liabilities are measured at fair value at the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). The carrying value of cash equivalents, accounts receivable, accounts payable, and accrued expenses approximate fair value because of the short-term nature of these instruments. Because of the variable-rate nature of our debt under our credit facility, our debt also approximates fair value. 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. Both of these assets are classified as long-term assets on our balance sheet, with the portion of the deferred compensation retirement plan assets expected to be paid within twelve months classified as current assets. 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 earnout liability recorded in conjunction with the Water Solutions acquisition is based upon achieving certain targets. The earnout is based on a target of adjusted earnings before interest, taxes, depreciation and amortization (EBITDA) in year three of the acquisition. The earnout liability was valued based upon a risk-neutral pricing analysis within a Monte Carlo simulation framework, which is a Level 3 input. The earnout liability is adjusted to fair value at each reporting date until settled. Changes in fair value are included in selling, general and administrative expenses in our Consolidated Statements of Income. The following tables summarize the balances of assets and liabilities measured at fair value on a recurring basis as of September 29, 2024 and March 31, 2024. 0 (In thousands) September 29, 2024 March 31, 2024 Assets Deferred compensation plan assets Level 1 $ 12,115 $ 10,042 Interest rate swap Level 2 $ 2,301 $ 4,268 Liabilities Earnout liability Level 3 $ 11,919 $ 11,235 Changes in the earnout liability measured at fair value using Level 3 inputs were as follows: (In thousands) Earnout liability at March 31, 2024 $ 11,235 Addition for acquisition $ — Fair value adjustments $ 684 Earnout liability at September 29, 2024 $ 11,919

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 2025 and fiscal 2024. 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 76,137 shares in the aggregate for fiscal 2025. 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 29, 2024: Shares Weighted- Unvested at beginning of period 145,477 $ 40.33 Granted 75,428 76.60 Vested (83,658) 38.31 Unvested at end of period 137,247 $ 61.49 We recorded compensation expense related to performance share units and restricted stock of $1.5 million and $2.6 million for the three and six months ended September 29, 2024, respectively. We recorded compensation expense related to performance share units and restricted stock of $1.0 million and $1.6 million for the three and six months ended October 1, 2023, 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 retainer, our directors, other than the Chief Executive Officer, receive restricted stock for their Board services. The restricted stock awards are generally expensed over a one-year vesting period, based on the market value on the date of grant. As of September 29, 2024, there were 6,734 shares of restricted stock with an average grant date fair value of $103.90 outstanding under this program. Compensation expense for the three and six months ended September 29, 2024 related to restricted stock awards to the Board was $0.2 million and $0.3 million, respectively. Compensation expense for the three and six months ended October 1, 2023 related to restricted stock awards to the Board was $0.1 million and $0.2 million, respectively.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies Disclosure [Text Block]	Commitments and Contingencies Environmental Remediation. In the fourth quarter of fiscal 2024, we recorded a liability of $7.7 million related to estimated remediation expenses associated with perchlorinated biphenyls ("PCBs") discovered in the soil at our Rosemount, MN facility during our expansion project. We acquired the property, which had prior heavy industrial use, in fiscal 2012. While the source of the PCBs is unknown, we have never brought PCBs onto the property or used PCBs on the site. The liability is not discounted as management expects to incur these expenses within the next twelve months. Given the many uncertainties involved in assessing environmental claims, our reserves may prove to be insufficient. While it is possible that additional expense related to the remediation will be incurred in future periods if currently unknown issues arise, we are unable to estimate the extent of any further financial impact. No expenses were charged against this liability during the three and six months ended September 29, 2024.
