Feb. 20 (Bloomberg) — Watts Water Technologies Inc., a water products manufacturer, reported fourth-quarter revenue of $359.2 million, “essentially flat” compared with a year- earlier due to the weakening of the euro to the U.S. dollar.

Sales for 2012 rose 1 percent to the highest since 2008 compared with a year ago, mainly from $51.5 million of acquisitions, the North Andover, Massachusetts-based company said late yesterday in a statement.
