how is water bypassing sediment filter?!

Glad you mentioned Silicone grease. Vaseline, and other lubricants can destroy an o- ring by its petroleum base. I prefer to use the food grade silicone lubricant I get on Amazon. I just spray a little bit on a q-tip and wipe the seal, then assemble. Works great on car weatherstripping as well, but the food grade part is not necessary for that stuff unless your dog likes to chew on it, but that's another problem.
