Troubleshooting
-
Leak at clamp joint: Verify even tightening and proper seating of the O-ring between tank halves.
-
Loose clamp: Ensure the spring is not compressed beyond normal range and the nut threads are clean.
-
Uneven clamp pressure: Confirm washers are flat and properly aligned before tightening.
Maintenance Tip
Inspect the spring and nut assembly every time the filter tank is opened. Replace the components if you notice rust, deformation, or loss of spring tension. Proper clamp tension helps maintain a safe and watertight seal on the filter tank.
