APR Supply Co. has purchased Pennsylvania plumbing and HVAC wholesaler W.G. Balph Co. Terms were not disclosed.

“The acquisition of Balph Co. represents a continuation of APR’s aggressive growth strategy,” said APR Chief Operating Officer David Robinson. “More specifically, this move is an extension of our existing joint venture business model.”

 Two Balph stores — one in Pittsburgh, the other in Greensburg, Pa. — will become APR branches, and the company will open two more APR Supply Co. locations in the Pittsburgh area, thanks to a venture with electrical supplier Schaedler Yesco. The two companies currently share 10 locations.
