Hey guys im from india, this is my first time with bulkheads, its cpvc, they came with 2 gaskets. Here is what iv read online, but still confused... 1) add gasket only on inside of the tank and dont use any silicone. 2) add gasket on both the sides 3) silicone ur entire gasket and use it on the inside and nut on the outside 4) keep gasket on the indside and use silicone on the outside, then tighten with nut, let it dry. 5) use an industrial grade putty and seal on the outside. Well guys i want a permanent leakproof seal, i dont mind using silicone and putty both. I also dont mind if the seal is permanent. Plz help.. here is wat i have. Gasket is not of a good quality i guess .
