What It Works With

The Watts FH-WWH works with most standard 10-inch and 20-inch filter housings in both slim (2.5-inch) and standard (4.5-inch) diameters. This half wrench is ideal for installations where space is limited or where a full wrench would be cumbersome, including under-sink systems, tight utility rooms, and residential point-of-entry setups. Compatible with Watts, Pentek, and most other major brand housings that use a standard wrench interface.

💧 A half wrench offers better access in cramped under-sink spaces and is easier to store than full-circle wrenches, but keep a rag handy when loosening housings to catch residual water.
