The Aqua-Pure™ 68434-32P water filter housing wrench is required for removing the water filter housing canister from the system’s head to remove and replace filters. You should only hand tighten the housing sump after replacing the filter. The wrench should not be used to tighten the water filter housing sump. Over tightening the sump can cause damage to the O-rings and make re-opening the housing sump very difficult.
This wrench is a plastic version of the #6 Metal Wrench.
