Poolaroo Pro Tip

When replacing a filter tank clamp assembly, inspect the tank O-ring seal at the same time. A worn or flattened O-ring is a common cause of pressure loss at the tank seam and is inexpensive to address while the clamp is already removed. Ensure all hardware included in this assembly is fully tightened and evenly torqued around the clamp band before returning the filter to service.
