How to Use:
Turn off the water supply and relieve the pressure inside the filter housing before attempting to remove the sump. Position the wrench around the housing and rotate it counter-clockwise to loosen the sump. After replacing the filter cartridge, lubricate the O-ring with food-grade silicone lubricant and hand-tighten the housing. Use the wrench only for light final tightening if required. Use the wrench only to loosen or lightly tighten the housing. Over-tightening may damage the housing or O-ring and make future maintenance more difficult.
