Parts Needed to Allow Gray Water and Black Water to Dump From the Same Valve

Question

Question:

I have a gray tank with the #T1001C valve. I have a sewer adapter like #F02-3112CL. At the moment I have adapters on both ends that let me use a 3/4inch hose in between. But with this setup it takes far too long for the tank to drain. Is there a 1-1/2inch hose available with appropriate adapters or a 3inch hose with appropriate adapters that will go between the valves 1-1/2inch MPT connection and the sewer adapters 3inch bayonet connection? Would it help to replace the 1-1/2inch MPT connection on the valve with #T1006-1 or similar?

It sounds like you might want to have a look at the Bristol Double RV Waste Valves - Elbow - Rotating - 3" and 1.5" Hubs to 3" Lug # 34466ND13AAR, which would allow you to dump your black and gray water tanks from the same hose. This elbow fitting connects to the 3" hub on your black water drain pipe and the 1-1/2" hub on your gray water tank, and allows you to use the # F02-3112CL with your 3" spigot connection hose.

You'll need to remove your old valves to install the Bristol Double RV Waste Valve # 34466ND13AAR, and use some Valterra ABS Solvent Cement - 1/4 Pint # A05-0303 to secure the pipes together. This would allow you to use all of your existing hoses and adapters and is a great solution to dump everything from one valve.

Hi Eric, So the Trailair system you were referring to needs standard center hangers, and the LRE doesn't use that, as you know, because they have the rubberized shear hanger. That means the Trailair won't work with what you have, but there is…
