iSpring wsp-50 spin down filter slowly leaking and cant stop leak
I am city water with a 3 stage whole home water filter system. I installed a iSring spin down fliter to protect the 3 stage filter incase a large amount of sediment got into the city water line. Yesterday when I was checking on the filter for the whole home filter system I noticed a small leak coming from the house of the spin down filter where it screws in to the brass upper. I checked the floor and noticed that the concrete was damp but not flooded so it had been leaking for a bit but slowly (about a drop every 15 seconds). I turned off my water and unscrewed the houseing thinking some dirt got into the o ring or the o ring went bad. Cleaned the housing, ran my finger on the spot where the o ring will press onto in the brass housing to make sure no dirt or cracks, put on new o ring, reinstalled. Still leaked. I tried barly tightening it thinking I over tighten it, no luck. I then tightened it very hard and it still leaked. I have tried putting tape and dope on the houseing threads but makeing sure the o ring was clear (I was getting desperate at this point) but still no luck. I dont see any cracks on the houseing and its not even 2 years old. Is this normal with iSpring filters? Anything else I can try? I do have water thanks to rubbing my two brain cells together when I installed the whole system and put in a bypass value, the only down side is that valve bypasses the whole filter sytem.
