Question:

I have a leak on both waste valves, so I pulled everything apart. Ive attached a half dozen photos to make this a little easier. Im pretty certain thats the right part for the grey tank is LaSalle Bristol Waste Valve Body for RV Gray Water w/ Coupler, Seals - 1-1/2inch Diameter 34439241. I cant find a match for the 3inch black tank, but Im thinking that LaSalle Bristol Waste Valve for RV Black Water Tank - 3inch Diameter - Spigot to Spigot 34466N4BB might work. Can you take a look at the attached images and tell me what you think? Thanks for the help! Josh

Hey Josh thanks for all of those pictures. After looking at them I can say both the LaSalle Bristol Waste Valve Body for RV Gray Water w/ Coupler # 34439241 for your grey tank and # 34466N4BB for your black tank is going to work perfect as a replacement. These look to be direct replacements so I don't imagine there'll be any hang-ups when you go to swap them out.

Just make sure to use some ABS solvent # 3447530889 to bind everything together and you'll be good to go.
