Headhunter Royflush issues
Another hurdle.
My fridge is in the bus, I wanted to test my connection from coach to the fridge to make sure its not leaking prior to putting fridge in its hole. My bus is still in winter mode since I havent had time to mess with that aspect of the coach. So I replace my water filter and push out the antifreeze and start filling up my water tank.
I prime the pump and it starts and water is flowing right away. So naturally I head inside the bus to see what’s running. Well my toilet is working with out me touching it. So I pull everything out from the sink and start my diag from there. After a few calls to friends on speed dial I start to get a better understanding for the system.
1. Check the diaphragm to make sure no debris, no issue there.
2. I check my air pressure diaphragm and its at 28, water still running.
3. Check switch timer, swap the leads, still runs. Disconnect both leads, still runs.
4. Pull power to switch, still runs.
5. Pull power to the diaphragm, toilet is still running.
6. Tested power to the switch, there is power.
This morning I called and headhunter and went over where I was at on this process. They stated they think something is off on the soleniod, I ordered a new valve and hope to install this week. I am told there should be a shut off valve prior to that solenoid also but the bus doesnt have one. I cant test any other part of the system as soon as the pump comes on it starts pushing water through the 1″ direct feed toilet line.
I will update how everything works when I get new parts installed.

I do not believe Liberty provided a shut off to the water supply to the flush valve.
If you can access the flush valve itself, and can separate the two halves if you clean the diaphragm and the housing of the valve itself, unless the diaphragm is not seating and shutting of the water that is all that is needed.
Usually a little dirt or crud inhibits flow to the other side of the diaphragm so it will not seat and shut off, or something is preventing it from sealing and shutting off water flow.
On your vintage coach you may also be missing a 1″ check valve ahead of the flush valve and if so definitely get one installed. If the flush valve is leaking your only solution is to turn off the pump and when pressure drops to zero water will siphon from the toilet back into the fresh water tank.

My ’99 has the 1″ check valve. That said, just because your coach has one, doesn’t mean it’s good. I drained the lines to work on the pump connections and the toilet drained. So, I’d check for proper operation. Pretty nasty to have toilet water back up into potable lines.

To confirm what I am reading is I should buy a 1″ check valve. Install that check valve before the toilet valve.

I did clean out the valve and make sure there was no debris.

Update, the new valve fixed the toilet.
Current water issues
1. Head hunter monitor on the fresh water or black water dont work.
2. My gray water dump has a small leak, hope to take valve off and clean and reinstall.
3. I need to bleach my system.
4. Have not turned hotwater on yet.
