Product Description
SW-3 Spanner Wrench for Big Blue Housings (10 inch): Home & Kitchen. Makes changing water filters easy. Use the SW-3 filter wrench only for twisting off water filter housing canisters. Use the SW-3 filter wrench to loosen the bottom of the housing during cartridge replacement. Slide circular end over housing until a snug fit is achieved and unscrew. Do NOT use the SW-3 housing wrench to secure the water filter canister to the water filter cap. Over tightening the sump can cause damage to the o-ring and make re-opening the water filter housing difficult. You should only hand tighten the housing sump. Can be used with #10 Big Blue whole house housings.
