Question:
We want to change to the Valterra electric valves for our camper. Our gray tank is 1 1/2 inches in size and the black tank is 3 inches. Can you tell me which valve we would need and any additional parts.

Hey Jill, thanks for reaching out!
We definitely have some options for you, but it looks like right now all that has been made are electronic waste valves for 3" openings, like the Valterra EZ Valve Electric Waste Valve # E1003VP - unfortunately there aren't any electric waste valves for a 1-1/2" opening.
If it's an all or nothing kind of situation then you might consider the Valterra Waste Valve Bodies w/ Flexible Cables # TC1372 which can keep you from having to borderline crawl under your RV to open up the valves, or you can swap the 3" to electric and just install the 1-1/2" Cable Valve # TC172 to get you as close as you can to what you're wanting.

Hey Jill, how did things go with the Valterra valve setup for your camper? Did you end up using the electric option for the 3-inch line and the cable valve for the gray tank? Your update could make it easier for others working on a similar upgrade.
