Question:

I would like to attach an aluminum handle valterra 3inch blade valve on the end of my sewer line on my travel trailer. To do that I need the blade valve with a male bayonet connection on one side and a female bayonet connection on the other side. This would offer me one more valve right before the connection of the sewer hose. This way when I remove the sewer cap, there is a valve right there that would keep all liquids in until I have the sewer hose securely connected and hooked up to the dump. The black and grey water valves on my rig are not water tight, resulting in fluids accumulating behind the cap and a mess when I remove the cap to secure the sewer hose.

While there isn't an adapter to go directly between the Valterra Waste Valve for RV Black Water Tank part # T50A can be added on in place of your current 3" lug cap in place now. Simply cut it off and attach this one using the LaSalle Bristol ABS Solvent Cement part # 3447530889. This will give you the valve in place to keep the stuff off of your hands.

The Valterra Bladex Waste Valve Body for RV Black Water Tank part # T1003VPM you looked at can be used to replace the existing valves you have and get rid of the leaking issue you currently have as a double assurance.
