Nice work!

[@kevinpackard]

Perfect. Thank you.

You forgot to mention there may be a screw or two to be removed also. I put a mirror behind to see it. Came out a lot easier with the screw out. Didn't have to take the toilet out!

mine had a screw holding it in on the bottom. it took a mirror to find it.

What is upper value called and how to replace

[@reneegalligher1820]

Ben, I see you are doing this outside of the RV. Is this just for demo purposes or do you have to pull the toilet?

[@BenStork]

This is just for demo purposes. As long as you turn off the water supply (turn off your pump) you should have no issues replacing the water valve while the toilet is still installed. If you do not drain your water line residual water will come out when disconnected. Just make sure you have a few extra towels (will be clean fresh water).

Thank you Ben. We figured that out from some other sites and from the Heartland Forums. Hubby already fixed it and all is well! Thanks!

I had a really hard time getting the hose off, it looked like it was heated on. I was going to replace that hose piece something from Lowes and 2 hose clamps. Should I be ok in doing so?

Yea, not mentioning the screw holding it in was a big mistake.

Useless.
