I just looked up the domestic 310 parts on google and got to the domestic parts list. Went from there. Good luck. Oh and it's easy to replace, even in place. The prongs are stiff but will release eventually. **Q: With this new part I do not have any leaks but a few times when you go flush I get no water. I have to turn the water on& off at the sink to flush...?** A: Mine did the same thing. When I installed the valve I didn't put the screw in to hold the valve in place. After I put the screw in I had no more problems. I get water in the bowl with every flush. **Q: What is the size of the thread?** A: There is no thread size for this valve. The supply line is clamped on. This is a valve for the toilet. **Q: I replaced mine due to a freeze issue and the new one will not shut off. Has there been problems with the end of the push in valve sticking?** A: My valve had an issue sticking open where I could not stop the water flow. Had to remove valve, sprayed WD-40 inside valve, valve doesn’t stick any longer. ## Customer Reviews ### ⭐⭐⭐⭐⭐ RV Toilet Valve Fix That Packs a Punch! *by T***N on June 7, 2025* I’m really pleased with this water valve kit for my RV toilet!
