Help with water problem

[andrei]

I need some help. My fresh water tank is taking on water from somewhere and the overflow on the passenger side started to drip. When I looked at the tank it was very full with a bulge on the top. However it did not seem like it was filling non-stop due to city water pressure, if that makes any sense. It was only dripping. I shut the city water off and also made sure the fill valve is in the correct upright position. We will use up the fresh tank water with the pump to get rid of some of the water. On the right side/bottom of the wet bay there are three pipes. Two low point valves which are closed and two for the winterizing fill which are both pointing up. Manual is not real clear on this and just calls for them to be in the "normal position" Entegra is closed and seems somewhat backed up due to the ice storms. Any ideas on what, and where to look? Until I use up some tank water I don't have enough room in the tank to turn city water back on and listen for water leakage into the tanks somewhere. Any help would be appreciated. Rig has been on the road for a month. I promise a picture and updated tag line.

Seems odd to me since the system is designed to dump excess over the side after the tank is full. You can empty the tank in the wet bay by opening the two furthest forward (I think) valves and turning on the pump.

Got to get rid of the bulge!
In the water compartment, the 3rd line from the left is your drain line line pull the lever down and the tank should be draining out right below the valve. Be prepared to entertain yourself, cause it really drains slowly

If the selector valve to select "tank fill" or "house" water is not selecting where the water is to go, it is not working or frozen. You do not say where you are or if you are in freezing conditions. Taking the valve apart is just a matter of unscrewing the water lines and looking to see if the selector is working or not.

If the over flow is not draining it is either frozen or plugged. Run a stiff wire or thin screwdriver up the pipe with the valve open, but be careful not to punch the one way valve in the tank.

The only place it can take on water is from the hose. I'd say your valve between house and tank fill is leaking. In addition, your overflow vent is blocked or shut off. You need to be careful, because the tank can split from the city water pressure. Even at only 45 lbs. of pressure (remember that's per square inch) multiplied by the large area of the tank sides, it can create enormous pressure that can rupture the tank or cause structural damage to the surrounding area around the tank. Until you solve the mystery, I'd only operate off the tank and water pump. Disconnect the hose when not filling the tank so no one turns on hydrant and causes damage to your RV.

My rig had your symptoms.

I ratcheted the fill/shore valve back an forth a few times. Worked. Must have been a wee bit O somethin in the valve. :-)

High water pressure will sometimes a nylon ball valve to pass water around the seal, and can be compromised with a speck of dirt in the line. Get an adjustable pressure regulator. I keep mine @45 psi.

Try turning off the water at the outside faucet then turn on the water pump, open an inside faucet and make sure there is no air. Close the inside faucet, turn off the pump and turn on the outside faucet. I don't know why, but this has stopped mine from doing the same thing as yours several times. Noel

By the way this was after I changed the tank fill-city water valve, which is a pain to change.

After all the kind suggestions I used the pump/tank through 10 this morning and my wife also did some wash. I played with the fresh/city valve and rotated it back and forth several times. Since we used all the water spigots, including the shower, since last night I am fairly sure there was no air in the lines by this morning. My fresh is at 50% at this point and I turned the city water back on and the pump off. So far so good- tank is still at 50% and I will continue to monitor it both with gauge and visually. My city pressure is steady at a tad over 45%. I also put a wire up the two vents on the passenger side of the coach and went as far as I could with no obstructions. I did not remove the fittings on the top of the fresh water tank since that would involve doing something with the "permaclamps" on the water lines. Hopefully it was just dirt or an improperly seated valve leaking into the tank, but that still does not explain the swollen tank with only a trickle coming out of the overflow?

It sounds like there is a blockage in the overflow line. You could try pressurizing the tank with the water pump, then trying a wire up the overflow tube and see if you can free up the blockage.

What year is the MH and have you had this problem before? If the MH is new, there could be some construction debris that has found it's way into the overflow.

Thanks for your answer. Our coach is a 2014 DEQ, about one month on the road. I agree with you that there has to be blockage in the tank overflow. Like I said earlier, I pushed a coat hanger wire as far up the two vents as I could get it. There are two loops (upside down U pipes with one about 2" higher than the other) on the passenger side. I can see through the loops and see no blockage, but there may be blockage at the the fitting connecting the pipes to the tank. Can you tell me how to pressurize the tank using the pump? Other than that I could try to take the fittings off, but I would have to replace the factory clamps, I do not have those fittings or that tool. I imagine a hose clamp nice and tight would do the job since they are not pressurized fittings? I have an adjustable pressure regulator from Valtera and its currently at 47psi. The tank has help at 50% fill since 11AM so it's been just about 12 hours with no leakage into the tank. there must have been dirt in the shore/fill valve. Thank you again for your help and concern, I really appreciate it.

Have you opened the access door (looks exactly like a storage bay door without a handle) and looked at the overflow tubes? The panel is held in place with 3-4 screws along the bottom and hinges up. Here's a pic of mine. The overflows are easily visible.

I think Dave just came up with the answer of what I was going to suggest with pressure on the water system using the pump. I like Dave's idea much better.
