mess and return the Delta and Porter-Cable lines to profitability. This caused Pentair to further review its holdings and look at ways to cut costs. It expanded its production in Taiwan and started to negotiate with the union of its Delta manufacturing facility to reduce payroll. In 2003 it was announced that negotiations had failed, and the Tupelo plant would close the following year. While operations were wound down in Tupelo Pentair continued to expand its water products business. In July 2004, Pentair bought WICOR Industries, the former water systems subsidiary of Wisconsin Energy, for $850 million. WICOR made water pumps, filters, and pool equipment components under the Sta-Rite, SHURflo, and Hypro brands. To help offset this purchase it sold its entire tool operation to Stanley Black & Decker that October. This marked Pentair's exit from the tool business. In 2005, Pentair bought some of the assets of APW for $144 million, including McLean Thermal Management, Aspen Motion Technologies, and Electronic Solutions, all of which provide thermal management products and integration services to the telecom, medical, and security industries.

The company has announced an agreement to acquire water filtration and separation firm Porous Media for approximately $225 million. It has said that it plans to continue an active course of acquisitions, especially to grow its business outside the American market. 2010s In 2012, Pentair Inc. (PNR) and Tyco International Ltd.

Tyco shareholders now own approximately 52.5% and former Pentair Inc. shareholders own approximately 47.5% of Pentair Ltd.
