Accounting Policies [Abstract]
Basis of Presentation and Responsibility for Interim Financial Statements	Basis of Presentation and Responsibility for Interim Financial Statements The accompanying unaudited condensed consolidated financial statements of Pentair plc and its subsidiaries (“we,” “us,” “our,” “Pentair,” or the “Company”) have been prepared following the requirements of the United States (“U.S.”) Securities and Exchange Commission for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by accounting principles generally accepted in the United States of America (“GAAP”) can be condensed or omitted. We are responsible for the unaudited condensed consolidated financial statements included in this document. The financial statements include all normal recurring adjustments that are considered necessary for the fair presentation of our financial position and operating results. As these are condensed financial statements, one should also read our consolidated financial statements and notes thereto, which are included in our Annual Report on Form 10-K for the year ended December 31, 2023. Revenues, expenses, cash flows, assets and liabilities can and do vary during each quarter of the year. Therefore, the results and trends in these interim financial statements may not be indicative of those for a full year. Our fiscal year ends on December 31. We report our interim quarterly periods on a calendar quarter basis. Recent U.S. Securities and Exchange Commission (“SEC”) final rules In March 2024, the SEC issued the final rules under SEC Release No. 33-11275, The Enhancement and Standardization of Climate-Related Disclosures for Investors. In April 2024, the SEC voluntarily stayed the new rules as a result of pending legal challenges. These rules, if adopted, will require registrants to disclose certain climate-related information, including Scope 1 and Scope 2 greenhouse gas emissions and other climate-related topics, in registration statements and annual reports, when material. Disclosure requirements, absent the results of pending legal challenges, may begin phasing in with our annual reporting for the year ending December 31, 2025. We are currently evaluating the impact the rules will have on our disclosures.

The total number of awards issued was approximately 0.5 million, of which 0.2 million were restricted stock units (“RSUs”), 0.2 million were stock options and 0.1 million were performance share units (“PSUs”). The weighted-average grant date fair value of the RSUs, stock options and PSUs issued was $75.70, $25.10 and $71.83, respectively. We estimated the fair value of each stock option award issued in the annual share-based compensation grant using a Black-Scholes option pricing model, modified for dividends and using the following assumptions: 2024 Risk-free interest rate 4.44 % Expected dividend yield 1.43 % Expected share price volatility 30.90 % Expected term (years) 6.5 These estimates require us to make assumptions based on historical results, observance of trends in our share price, changes in option exercise behavior, future expectations and other relevant factors. If other assumptions had been used, share-based compensation expense, as calculated and recorded under the accounting guidance, could have been affected. We based the expected life assumption on historical experience as well as the terms and vesting periods of the options granted. For purposes of determining expected share price volatility, we considered a rolling average of historical volatility measured over a period approximately equal to the expected option term. The risk-free interest rate for periods that coincide with the expected life of the options is based on the U.S. Treasury Department yield curve in effect at the time of grant.

Accounts Receivable	Accounts Receivable All trade receivables are reported on our Condensed Consolidated Balance Sheets at the outstanding principal amount adjusted for any allowance for credit losses and write-offs, net of recoveries. We record an allowance for credit losses, reducing our receivables balance to an amount we estimate is collectible from our customers. Estimates used in determining the allowance for credit losses are based on current trends, aging of accounts receivable, periodic credit evaluations of our customers’ financial condition, and historical collection experience as well as reasonable and supportable forecasts of future economic conditions. Write-offs are recorded at the time all collection efforts have been exhausted. We generally do not require collateral. We review our allowance for credit losses on a quarterly basis. Activity related to our allowance for credit losses is summarized as follows for the nine months ended September 30, 2024: In millions September 30, Beginning balance $ 11.2 Bad debt expense (0.6) Write-offs, net of recoveries (1.2) Other (1) 0.5 Ending balance $ 9.9 (1) Other amounts are primarily the effects of changes in currency translation and the impact of allowance for credits.

Pentair, Pentair Finance S.à r.l (“PFSA”) and Pentair, Inc. are parties to a credit agreement (the “Senior Credit Facility”), with Pentair as guarantor and PFSA and Pentair, Inc. as borrowers, providing for a $900.0 million senior unsecured revolving credit facility. During the second quarter of 2024, PFSA repaid $200.0 million of term loans under the Senior Credit Facility. The revolving credit facility has a maturity date of December 16, 2026. Borrowings under the Senior Credit Facility bear interest at a rate equal to an alternate base rate, adjusted term secured overnight financing rate, adjusted euro interbank offered rate, adjusted daily simple secured overnight financing rate or central bank rate, plus, in each case, an applicable margin. The applicable margin is based on, at PFSA’s election, Pentair’s leverage level or PFSA’s public credit rating. As of September 30, 2024, total availability under the Senior Credit Facility was $900.0 million. In addition, PFSA has the option to request to increase the revolving credit facility and/or to enter into one or more tranches of term loans in an aggregate amount of up to $300.0 million, subject to customary conditions, including the commitment of the participating lenders. In addition, Pentair and PFSA are parties to a senior unsecured term loan facility (the “Term Loan Facility”), with PFSA, as borrower, Pentair, as guarantor, providing for an aggregate principal amount of $1.0 billion. The Term Loan Facility has a maturity date of July 28, 2027, with required quarterly installment payments of $6.3 million which began on the last day of the third quarter of 2023 and increased to $12.5 million on the last day of the third quarter of 2024. During the nine months ended September 30, 2024, PFSA repaid the remaining $162.5 million of quarterly installments on the Term Loan Facility, such that PFSA is not required to make any further quarterly installment payments. As of September 30, 2024, the remaining obligation of $825.0 million matures on July 28, 2027. Th e Term Loan Facility bears interest at a rate equal to an alternate base rate, adjusted term secured overnight financing rate, or adjusted daily simple secured overnight financing rate, plus, in each case, an applicable margin. The applicable margin is based on, at PFSA’s election, Pentair’s leverage level or PFSA’s public credit rating. Our debt agreements contain various financial covenants, but the most restrictive covenants are contained in the Senior Credit Facility and the Term Loan Facility. The Senior Credit Facility and the Term Loan Facility contain covenants requiring us not to permit (i) the ratio of our consolidated debt (net of our consolidated unrestricted cash and cash equivalents in excess of $5.0 million but not to exceed $250.0 million) to our consolidated net income (excluding, among other things, non-cash gains and losses) before interest, taxes, depreciation, amortization and non-cash share-based compensation expense (“EBITDA”) on the last day of any period of four consecutive fiscal quarters (each, a “testing period”) to exceed 3.75 to 1.00 (or, at PFSA’s election and subject to certain conditions, 4.25 to 1.00 for four testing periods in connection with certain material acquisitions) (the “Leverage Ratio”) and (ii) the ratio of our EBITDA to our consolidated interest expense, for the same period to be less than 3.00 to 1.00 as of the end of each fiscal quarter. For purposes of the Leverage Ratio, the Senior Credit Facility and the Term Loan Facility provide for the calculation of EBITDA giving pro forma effect to certain acquisitions, divestitures and liquidations during the period to which such calculation relates. In addition to the Senior Credit Facility and the Term Loan Facility, we have various other credit facilities with an aggregate availability of $21.0 million, of which there were no outstanding borrowings at September 30, 2024. Borrowings under these credit facilities bear interest at variable rates. We have $19.3 million of senior notes maturing in the next twelve months. We classified this debt as long-term as of September 30, 2024 as we have the intent and ability to refinance such obligation on a long-term basis under the revolving credit facility under the Senior Credit Facility.

Derivatives and Financial Instruments	Sep. 30, 2024
Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Financial Instruments	Derivatives and Financial Instruments Derivative financial instruments We are exposed to market risk related to changes in foreign currency exchange rates and interest rates on our variable rate indebtedness. To manage the volatility related to these exposures, we periodically enter into a variety of derivative financial instruments. Our objective is to reduce, where it is deemed appropriate to do so, fluctuations in earnings and cash flows associated with changes in foreign currency exchange rates or variable interest rates. The derivative contracts contain credit risk to the extent that our bank counterparties may be unable to meet the terms of the agreements. The amount of such credit risk is generally limited to the unrealized gains, if any, in such contracts. Such risk is minimized by limiting those counterparties to major financial institutions of high credit quality. Foreign currency contracts We conduct business in various locations throughout the world and are subject to market risk due to changes in the value of foreign currencies in relation to our reporting currency, the U.S. dollar. We manage our economic and transaction exposure to certain market-based risks through the use of foreign currency derivative financial instruments. Our objective in holding these derivatives is to reduce the volatility of net earnings and cash flows associated with changes in foreign currency exchange rates. The majority of our foreign currency contracts have an original maturity date of less than one year. At September 30, 2024 and December 31, 2023, we had outstanding foreign currency derivative contracts with gross notional U.S. dollar equivalent amounts of $15.7 million and $23.9 million, respectively. The impact of these contracts on the Condensed Consolidated Statements of Operations and Comprehensive Income was not material for any period presented. Cross currency swaps At September 30, 2024 and December 31, 2023, we had outstanding cross currency swap agreements with a combined notional amount of $950.0 million and $940.2 million, respectively. The agreements are accounted for as either cash flow hedges, to hedge foreign currency fluctuations on certain intercompany debt, or as net investment hedges to manage our exposure to fluctuations in the Euro-U.S. Dollar exchange rate. We had deferred foreign currency losses of $39.9 million and $51.6 million at September 30, 2024 and December 31, 2023, respectively, recorded in Accumulated other comprehensive loss associated with our cross currency swap activity. The periodic interest settlements related to our cross currency swap agreements are classified as operating activities. The cash flows that relate to principal balances are classified as financing activities for the cash flow hedges on intercompany debt and investing activities for the net investment hedges. In August 2024, we entered into a transaction to early terminate and cash settle a €150 million cross currency swap agreement, resulting in a net cash payment of $16.1 million, of which $16.4 million is included in investing activities and $0.3 million of interest income is included within operating activities on the Consolidated Statements of Cash Flows. Subsequent to the termination, we entered into new cross currency swap agreements with euro notional amounts matching the original swap agreement. Hedging of variable interest rates We manage our exposure to certain interest rate risks related to our variable rate debt through the use of interest rate swaps and collars. We enter into these agreements to hedge the variability of interest expense and cash flows attributable to changes in interest rates of our variable rate debt. As of September 30, 2024, we had an aggregate notional amount of $300.0 million and $200.0 million in interest rate swaps and collars, respectively, that are designated as cash flow hedges. Unrealized gains and losses related to the fair value of the interest rate swaps are recorded in Accumulated other comprehensive loss on our Condensed Consolidated Balance Sheets. We had an unrealized loss of $1.7 million and an unrealized gain of $0.3 million at September 30, 2024 and December 31, 2023, respectively, recorded in Accumulated other comprehensive loss associated with our interest rate swap and collar activity. The periodic interest settlements related to our interest rate swaps and collars are classified as operating activities. Fair value measurements Fair value is defined as 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. Assets and liabilities measured at fair value are classified using the following hierarchy, which is based upon the transparency of inputs to the valuation as of the measurement date: Level 1: Valuation is based on observable inputs such as quoted market prices (unadjusted) for identical assets or liabilities in active markets. Level 2: Valuation is based on inputs such as quoted market prices for similar assets or liabilities in active markets or other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. Level 3: Valuation is based upon other unobservable inputs that are significant to the fair value measurement. In making fair value measurements, observable market data must be used when available. When inputs used to measure fair value fall within different levels of the hierarchy, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement. Fair value of financial instruments The following methods were used to estimate the fair values of each class of financial instrument: • short-term financial instruments (cash and cash equivalents, accounts and notes receivable, accounts payable and variable-rate debt) — recorded amount approximates fair value because of the short maturity period; • long-term fixed-rate debt, including current maturities — fair value is based on market quotes available for issuance of debt with similar terms, which are inputs that are classified as Level 2 in the valuation hierarchy defined above; • foreign currency contracts, interest rate swap and collar agreements — fair values are determined through the use of models that consider various assumptions, including time value, yield curves, as well as other relevant economic measures, which are inputs that are classified as Level 2 in the valuation hierarchy defined above; and • deferred compensation plan assets (mutual funds, common/collective trusts and cash equivalents for payment of certain non-qualified benefits for retired, terminated and active employees) — fair value of mutual funds and cash equivalents are based on quoted market prices in active markets that are classified as Level 1 in the valuation hierarchy defined above; fair value of common/collective trusts are valued at net asset value (“NAV”), which is based on the fair value of the underlying securities owned by the fund and divided by the number of shares outstanding. The recorded amounts and estimated fair values of total debt, excluding unamortized issuance costs and discounts, were as follows: September 30, December 31, In millions Recorded Fair Recorded Fair Variable rate debt $ 825.0 $ 825.0 $ 1,187.5 $ 1,187.5 Fixed rate debt 819.3 834.9 819.3 824.5 Total debt $ 1,644.3 $ 1,659.9 $ 2,006.8 $ 2,012.0 Financial assets and liabilities measured at fair value on a recurring and nonrecurring basis were as follows: September 30, 2024 In millions Level 1 Level 2 Level 3 NAV Total Recurring fair value measurements Interest rate contract liabilities $ — $ (1.7) $ — $ — $ (1.7) Foreign currency contract liabilities — (60.7) — — (60.7) Deferred compensation plan assets 14.9 — — 14.3 29.2 Total recurring fair value measurements $ 14.9 $ (62.4) $ — $ 14.3 $ (33.2) December 31, 2023 In millions Level 1 Level 2 Level 3 NAV Total Recurring fair value measurements Interest rate contract assets $ — $ 0.3 $ — $ — $ 0.3 Foreign currency contract assets — 0.2 — — 0.2 Foreign currency contract liabilities — (70.0) — — (70.0) Deferred compensation plan assets 12.1 — — 14.0 26.1 Total recurring fair value measurements $ 12.1 $ (69.5) $ — $ 14.0 $ (43.4)

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We manage our affairs so that we are centrally managed and controlled in the United Kingdom (“U.K.”) and therefore have our tax residency in the U.K. The provision for income taxes consists of provisions for the U.K. and international income taxes. We operate in an international environment with operations in various locations outside the U.K. Accordingly, the consolidated income tax rate is a composite rate reflecting the earnings in the various locations and the applicable rates. The effective income tax rate for the nine months ended September 30, 2024 was 14.1%, compared to 14.5% for the nine months ended September 30, 2023. We continue to actively pursue initiatives to reduce our effective tax rate. The tax rate in any quarter can be affected positively or negatively by the mix of global earnings or adjustments that are required to be reported in the specific quarter of resolution. The total gross liability for uncertain tax positions was $36.8 million and $38.6 million at September 30, 2024 and December 31, 2023, respectively. We record penalties and interest related to unrecognized tax benefits in Provision for income taxes and Net interest expense , respectively, on the Condensed Consolidated Statements of Operations and Comprehensive Income, which is consistent with our past practices.

Segment Reporting [Abstract]
Segment Information	Segment Information We are composed of three reporting segments: Flow, Water Solutions and Pool. We evaluate performance based on net sales and reportable segment income and use a variety of ratios to measure performance of our reporting segments. These results are not necessarily indicative of the results of operations that would have occurred had each segment been an independent, stand-alone entity during the periods presented. Reportable segment income represents operating income of each reportable segment inclusive of equity income of unconsolidated subsidiaries and exclusive of intangible amortization, costs of restructuring and transformation activities, impairments, legal accrual adjustments and settlements and other unusual non-operating items. “Corporate and other” activity primarily consists of corporate expenses not allocated to the segments, including executive office, board of directors, and centrally-managed corporate functional or shared service costs related to finance, human resources, communications and corporate development. These activities do not meet the criteria for a stand-alone reporting segment under accounting standards codification (“ASC”) 280.
