INSTALLATION & USE
How to Use the WR-100 Filter Wrench
- Shut off water supply and release pressure from the housing by pressing the red pressure release button on top of the filter housing.
- Position the WR-100 wrench around the filter housing sump, ensuring full contact around the circumference for even pressure distribution.
- Turn counterclockwise with steady, firm pressure to loosen the housing. Avoid jerking motions that could crack the housing or damage the threads.
- Once loosened, remove the wrench and finish unscrewing the housing by hand to access the filter cartridge.
COMPATIBILITY
Works With Multiple Housing Sizes
The Watts WR-100 is designed as a universal wrench that fits most standard 10-inch filter housings from Watts, Pentek, Culligan, GE, and other major brands. The full circle design distributes torque evenly around the housing, reducing the risk of cracking compared to strap-style wrenches. Compatible with both clear and opaque housings in slim and standard diameters commonly used in under-sink, whole house, and point-of-use water filtration systems.
🔧 Pro Tip: Before using the wrench, wipe the housing threads with a clean cloth and apply a thin layer of food-grade silicone grease to the o-ring. This reduces friction and makes future filter changes significantly easier while protecting the seal.
