If you need to replace the entire housing, the Watts W10FFPH1CBPR clear whole house filter housing can be purchased here. The Watts W10FFPH1CBPR housing is the same size and uses the same water filters. The Watts housing has the same 1" inlet/outlets. However, the Watts housing uses a different o-ring and wrench than the Ametek housing. The Watts parts are listed on the Watts housing page.
