I just installed a new Filstar xp m and i can't stop the water from leaking at the tank end return fitting.
I have taken it apart and reinstalled it.
I secured it with the factory clamp and an adjustable hose clamp and it still leaks.
I'm afraid to tighten to much on the clamp for fear of breaking or distorting the plastic pipe.
Has anyone run into this problem before? if so what was the fix?
I am thinking about making my own out of 1/2" cpvc.
