water leak near city water hook up

Sounds like the valve that switches between city water usage, and filling the freshwater tank may be leaking? If that is the vent for the fresh water tank, it sounds like the tank may be full.... Your tag says you are from Ohio. is that where you are now? Sounds like time to disconnect the water supply, and winterize?

You have a "KantLeak" Valve. I advise looking on the Thor forum and DRV section.

No....we are fulltimers now in Florida and heading to Las Vegas March 1st......I will see if water tank is full and then, if so, can at least drain it and leave drain open while I look for solution.....I will look at KantLeak valve as well.

Fulltiming....that sounds good. Let us know what you find!

well, I think you guys are on target. Sure enough, the water tank was full...turned water source off; drained the tank; turned water source back on and get city water but now my small leak is coming out the water tank drain hose instead of the 'vent' hole....Think I will measure the rate of leakage.....so now I don't think I have to worry about a freeze at night, and need to see what is involved in fixing it...

Well, that's progress! Probably will be a simple fix in the end. At least it's something manageable being able to leave the tank drain open. I don't own a DRV (I wish I did), but it sounds like the diverter valve needs a new seal. You might exercise that valve a bit, switching back and forth. Could be something as simple as some debris in it, although probably not...doesnt hurt to try.

The water pump check valve could be leaking city water back into the fresh water tank. I had that problem so I installed a one way check valve on the water pump output line. Cost less than $10.00

I haven't used the water pump this year....do you think that still remains a possibility ? I am trying to 'exercise the diverter valve and see if that leads anywhere.....I may have to wait a few days for the drip (if it continues) to wind its way down the drain hose.....hopefully the 78 sunshine degree weather without a cloud in the sky doesn't distract me from the task at hand.

Yes, water pump check valve is a possibility too. Even though on city water, there is still pressure to the pump (at least on my rig there is). You could close your tank drain, let some water accumulate, and switch over to pump, and run that for a bit too. Sometimes the pump check valve can leak back into the tank. Otherwise you can add an inline check valve in the suction side of the pump, or replace the pump entirely.

ok I am to have to go see how all the plumbing lines are set up...I haven't had to mess with them ever....Is a check valve easy to identify ? I may have to call one of the mobile repair guys because I am starting to get over my head
