Fresh Water Tank Overflow

[Zmax73]

2001 H345 Vantare. Connected water supply & turned on, fresh water fill switch not operating, about 5mins later water overflowing from fresh water tank. Went to connect sewer hose & found fresh water (I assume) draining thru discharge line with black & grey water tank valves closed. Anyone got a direction for me to take for troubleshooting ?
Got water at faucets & toilet flushes also.

I had similar problem and found that you need to recalibrate the sensors that tell your auto fill to turn off. Mine are headhunter sensors if I remember correctly. Your manual should give you a detailed process for recalibrating. Fairly simple process.

Make sure if you have fresh water flush valves on your grey and black tanks that they are shut off. If not, you can fill your tanks with fresh water and it can back up into your shower, ect.

ZMAX, what did you determine was the problem? Just curious and would like to know.

Pete,
Had a bad fresh water fill solenoid valve. $189 ! Tried to clean it up & adjust ,but no luck. 2001 Vantare with valve located on generator side inside the water manifold & water pump bay. It`s mounted just behind the panel inside bay & relatively easy to access. Hope this helps.

My .02 worth on this is if you don't have auto fill and I do, I still choose to fill my tank manually and dump at the same time. I turn the water off at the supply manually. This is not an inconvenience just the way I do it. My methods gives me peace of mind and no problems, unless I get to talking to someone around the park and I forget to turn the water off. If you didn't pick it up above, I run off the bus water pump and not the supply pressure, it can take it and I don't have to worry about over/under pressure problems should the pressure regulator go south or the park supply go dead. Just my way of doing things.

I just ordered this valve today, apparently it in bay 5. I tried changing the tank level sensor as we thought it might be cooked and it controls the GND to the valve. No Joy, so now we will change the valve.

Thanks Pete for that advice. Yes they`re closed.

Tony,
Thanks for the reply. I don`t have manuals on these. Searched the headhunter website for them but since they`re older models none found. Do u have the them? These are 2Q models with a reset button on the bottom & no adjustment.

Spoke to Headhunter rep today & he said to use model WTS on their website as the calibration technique. He mentioned the TS1501 box which houses the pump control circuitry. I have`nt found the box yet & wonder if iIhave one or the calibrating of the tank sentry`s will do the trick?
