WaterFilters.NET carries spanner wrenches for American Plumber, Ametek Kleen-Plus, AquaPure, Culligan, CUNO, Doulton, GE, Hydrotech, Liquatec, Microline, Pentek, Teledyne, US Filter, Waterpik, Watts Flowmatic and many other housing brands. Housing Wrenches are used to loosen water filter housing sumps in order to replace filters, parts, or perform system maintenance. DO NOT use wrenches to tighten the filter sump back onto the water filtration system because the o-ring may be damaged by securing the water filter lid too tight. Helpful Hint: Look at the dimensions of the wrenches below to determine if the wrench will work with your housing. Your housing (not the filter that is used inside your housing) determines your wrench size.
