Pentair is acquiring Hydra-Stop LLC for $290 million in cash, with the deal expected to close by year-end. The acquisition will enhance Pentair's existing solutions and support the water needs of growing cities, with Hydra-Stop's 50 employees and nearly $50 million in sales in 2025. The deal is seen as strategic, aligning with Pentair's mission to sustainably move and improve water worldwide.

In a strategic move to bolster its water solutions portfolio, Pentair plc (PNR) has announced the acquisition of Hydra-Stop LLC for approximately $290 million in cash. The deal, expected to close by the end of 2025, aims to enhance Pentair's capabilities in supporting the water needs of growing cities [1].

Hydra-Stop, a U.S.-based manufacturer of specialty valve solutions, is currently owned by Madison Industries. With approximately 99% of its sales originating from the United States, the company is projected to generate around $50 million in sales in 2025, with margins close to 30% [1].

The acquisition is set to strengthen Pentair's Commercial and Infrastructure business by expanding its solutions that help municipalities and service providers maintain water flow and limit losses. De’Mon Wiggins, executive vice president and president of Pentair Flow, described the deal as "a strategic acquisition" that aligns with the company's mission to sustainably move and improve water worldwide [1].

Pentair, which held $143 million in cash and cash equivalents as of June 30, 2025, has stated that the deal is subject to regulatory clearance and other standard conditions. Upon completion, Hydra-Stop will be integrated into Pentair's Commercial and Infrastructure business unit under its Flow segment [1].

The pre-market trading saw Pentair's stock at $104.47 on the New York Stock Exchange, down by 0.49% from the previous close [2]. Investors seeking broader exposure to the sector can consider ETFs such as the Invesco Water Resources ETF (PHO) and the First Trust Water ETF (FIW) [1].
