Question:

Hello, I have a 2003 Titanium that has cable actuated waste valves - I hate them and they dont close all the way. Im going to make it so they are always open and I want to put one of the Valterra double 3inch valve sets into the exterior pipe the cable valves are in the sealed underbelly. I was looking at the T84 and T84B, but I dont know which one I need. Im going to essentially cut the pipe and this product inline whichever one I need. I dont know if I need the one with the hubs or the one with the spigots, and I dont know if I need anything else to these inline. Ive attached a photo to help better explain what Im trying to do. Please let me know everything I need to do this so I can order the parts - the photo has annotations showing where I want the valves, etc. I need a cap for the one end as well youll see in the photo - do you carry those? Thank you!

Helpful Expert Reply:

The double valve you need to install on the 3-inch waste pipe in the photo is part # T84.

This is the female valve designed to fit over a 3-inch pipe.

To cap the 3-inch line you would need part # T50B. This is a waste valve that comes with a 3-inch bayonet cap.

If you are wanting to cap the 1-1/2 inch waste line you can use part # T1001C. This has the hub that fits over the 1-1/2 inch waste line and a threaded cap included.
