Common sense to most but worth mentioning again. The main reasons for water leaking into the Valentis is not properly seating the gasket so it protrudes at least 1/4" above the sealing surface; and over or under tightening the 8mm nuts. The nuts should be tightened sequentially to 40 in lbs. If installed properly no sealant is needed.
I used a Harbor Freight 1/4" drive, 20-200 in lbs, torque wrench with a 1/4" to 3/8" adapter and a deep well 8mm socket.
