Recommended Solution When RV Waste Valve Handles Are Hard To Reach
Question:
Thanks Kevin. Great answer and exactly what I needed to know I'll go with Valterra. Here is another one I hope you can answer. My existing gate valves are hard to reach, so I'm moving them out to the edge of the trailer with a Valterra T68. Can I eliminate the original gate valves by simply removing the valve and bolting the flanges together using either a gasket or sealant? Thanks so much!

Expert Reply:
The flanges typically have a gasket between them and the gate valve with a groove in the valve holding them in place. Putting two flanges together with just the gaskets touching each other instead of having an actual groove in the plastic to sit against will most likely leak over time. The safest bet is to cut off the flanges and use some couplings (3" # D50-2935 or 1-1/2" # D50-2933) along with some straight pipe to fill in the gap.
You could also check out the cable actuated gate valves we carry like part # TC1372, which can replace both of your gate valves with ones that have a 72" cable that can be mounted in a much easier to reach location.
