Replacement Waste Valve Assembly for a 2007 Keystone Passport Ultralite

Question:

I have a 2007 Keystone Passport Ultralight and the grey water valve was broken prior to my purchase of the trailer. I am looking to replace the whole connection with both drain stops. I had a new drain valve installed but it leaks due to one of the bolt tabs being broken. Not 100 sure what size pipes come off of the tanks so I can order the correct assembly.

I would love to help but I do not have any information that tells me what size drain pipes are on your 2007 Keystone Passport Ultralite so you will need to measure this for yourself. The standard size is 1-1/2" for the grey water tanks and 3" for the black water tanks. If this is what you have then you will want to use the Double RV Waste Valves part # T80. The grey water tank could also be a 3" diameter and if that is the case then you will want to use the Double RV Waste Valves part # T84. In order to attach the new valves I recommend using the Valterra ABS Solvent Cement part # A05-0303.
