Watts 20" Large Water Filter Housing (Watts FH10BL1PR) is an extra-wide filter housing that accommodates all large 20" x 4 1/2" Full Flow water filter cartridges. Made of durable, reinforced polypropylene that is resistant to a variety of chemicals.

Topping the housing off is a high-flow black polypropylene cap with a 1" female pipe thread port that allows water to pass through rapidly.

The thick side walls and buttress thread design allows for superior sealing and security. This along with the already larger filter capacity makes large housings a popular choice for high flow whole house applications.
