Auto fill valve trouble shooting

Yahoo Message Number: 113937
After auto filling the fresh water tank, about 20%, I turned the water pump and auto fill off at the Silverleaf whole coach monitor. Then I went outside and turned the shore water off. I then started to unscrew the hose and it was under pressure. As I unthreaded the hose, water sprayed out under pressure, like I hadn't turned the shore water off. As it leaked, I could hear the coach's water pump engage. It was pressurizing the hose. As I got the hose off the spigot the coach water pump stopped.

Does anyone here know how to troubleshoot this problem? There is an auto fill tank valve, a switch in the water bay as well as bathroom, and diodes (somewhere). It is a 2005 Magna.

Thanks,
Tom

Hi George,
There is a check valve to prevent this from happening. You may notice your pump cycle as well (No outside water connection) this is an indication this check valve is leaking.
You will have to pull the cover in the bay off to it, remove it, take it apart, clean it, reassemble and you will be good.
While you are in the bay, check that the water pressure regulator is working as well, mine was stuck at full open so whatever water pressure was present is what I received. I tried to repair with no luck so I installed a short hose in place and went to an external regulator.

Also, I usually dry camp so the "Full" level was never correct and would shut off about 75% full. I raised the top sensor to the very top of the tank and it's pretty close now.
