I'm a real amateur, so please go easy. I installed a whole home water filter in my basement and there is a persistent dripping that I can’t solve. The plastic body of the filter has a 1” thread on it, but the house’s main water pipe is ¾” copper pipe. I used a 1” to ¾” plastic reducer (kind of looks like a nut, but with ¾” size threads on the inside) and then a ¾” SharkBite adapter screwed into the plastic reducer. On both joints I just used Teflon tape (about 3-4 revolutions). The “IN” side of the filter does not leak, but the “OUT” side has a small drip. I tried disassembling and then reassembling, but the dripping is still there. Note that both the plastic and copper adapters can still be turned, but I don’t think that’s the problem because the other side does not leak and it’s not on as tight. Since the leak is so small and I will not be covering this area with drywall (I need to have access to change the filters) I was thinking of putting some sort of silicone or other epoxy? Any advice with that?
