It's three thirty on a lonely highway 30 miles out of town. Suddenly, a tire on my van explodes. I pull to the side and there is nothing left of the tire. Unfortunately, it's also a tire in front of the port dump valve. Nothing remained but fragments of broken pipes. I can't even imagine what liquids are leaking. Fast forward to the next morning. When I get home, I'm pondering how much this mess is going to cost me. The RV dealer gave me a price to replace the relief valve assembly, which was almost ridiculous. What to do? Revain to the rescue! This Valterra build is an exact copy of my old build, now lying somewhere on a deserted highway in a puddle of stinky juices and torn rubber. Installation was easy. I had to buy some black ABS tubing from a hardware store to patch what was missing. Glued and voila, like new. The total price was less than 1/4 of the price offered by the RV dealer. For the price of this kit you can't even buy just the valves. One caveat - the valve handles are straight T-shaped, not the intricately curved ones shown in the photo. **Edited to add: In my valve assembly, the drain valve handle is painted gray and the drain valve handle is painted black. Nice gesture. ****Edited again to add: They changed the image to match the build that looks like now, with straight T-handles. You need to use ABS pipe and ABS cement to glue the pipes together. Seriously, it took me about a half hour to fix my valve, including measuring and cutting new 1-1/2 inch pipes and elbows where they had been broken by a blowout tire. The valves are sleeve mounted so you can turn them in any direction. In my case I was concerned that the gray pipe would be attached with enough slope for proper drainage and took great care to line it up during trial installation and then glue it. But then I found that I could just twist the body valve and get it the way I needed it, I really rethought it. I would rate it SIX stars if they had it. It really saved me a lot of money and my wife thought I was an RV mechanic.
