Review on 💧 Valterra T1001-9VP Bladex Waste Valve Seals - 1.5" - Efficient Replacement Seals for Superior Waste Valve Performance by Noel Schmits

I had a pair of Valterra 6001 valves on the drain pump outlets and one of them was leaking. I originally planned to get an internal valve assembly and replace it, but these days they were hard to find. The manufacturer states that these seals are a necessary replacement when only the seals (rather than the O-ring along the steel stem of the valve handle) are defective. It was easy for me to swap them out as I had access to remove and work on the entire valve. Other reviews say that if you need to pull the center assembly out while leaving the valve body in place, make sure you install the valve closed so the new gaskets don't get caught. Be sure to lubricate with silicone grease, etc. A pack of two gaskets secures a valve assembly.
