Question:

Hello, I want to relocate one of my waste drain hose fittings to reduce the length of the drain pipe on my fifth wheel. The drain pipe that is accessible under the RV is 1 1/2inch pipe. I need the 3inch hose connection to 1 1/2inch pipe adapter but cant seem to locate the parts on the website ?? I simply want to be able to mount the drain termination to hose part directly to the end of the cut 1 1/2inch drain pipe. For some reason the photo will not upload.... Thanks,

What you can do is hook the Valterra Eccentric Tank Reducer - RV Gray Water - 3" Spigot to 1-1/2" Hub Item # T1041-1 onto your 1-1/2" pipe using some Valterra ABS Solvent Cement - 1/4 Pint Item # A05-0303 and a hose clamp.

Next you'll hook in the Valterra RV Sewer Termination Adapter - 3" Lug Fitting to 3" Spigot Item # T1029-1 using some # A05-0303 and a hose clamp.

If your hose has the bayonet end or if you have no end on the hose you can just hook it in as well using a hose clamp.
