Water tank overflow

Has happened twice.

Started out with tank about 1/2 full. Hooked up hose to use campground water. After several days noticed water spilling out of the overflow valve near hose bibb. Looked and found tank was completely full.

Called Escape first time. They said: use water in the tank and pump for a while. It will drain tank a bit so it doesn't over flow and all will be well. They said: it happends. Some anomalie (weird thing) about the system. In effect, live with it.

We did.

Happened again this Spring.

What's going on here? Sounds like the fresh water system is filling the tank slowly but surely.

I can live with it, but it's annoying.

Anyone else have this problem? Find a solution?

I just spoke with the owner of a 19 who described the same issue. He said it was caused by a faulty water pump and that Escape was aware of the problem. He replaced the pump and the problem was solved.

So, isn't there a check valve between the fresh water tank and pump?

The only check valve I know of is the one in the one that's built into the city water inlet. Makes sense though that there should be one on the output of the pump.

I put one of these in my Casita:

Whether it is a separate check valve or not, the water pump must block reverse flow to work. If it leaks back slightly, the effect will be slow filling of the tank.

These water pumps are multi-chamber diaphragm pumps driven by a cam on a shaft from the motor. I suppose it is possible that if the shaft stops at just the wrong point they may be more prone to allow backflow (thus it could be a sporadic anomaly), but since nearly every RV is plumbed the same as an Escape, all RV pumps should reliably block flow back to the tank.

Possible fixes are
  1. repair or replace the pump
  2. add a check valve between the pump and where it joins the line from the city water inlet
A check valve could be a quick fix if a replacement pump is not available, and can be included as a backup or complement to the pump, but I think that the proper solution is to make the pump work correctly.

This may not be the right model, but a diagram and description of Repair Parts For Shurflo 2088 Series Water Pumps shows a typical design; backflow should be stopped by the valve on each of three diaphragm sections, but it also has a separate check valve (item 2 in the diagram), probably to protect the rest of the pump from excessive city water pressure (suggesting that the pump manufacturer does not expect an external check valve to be installed). Again this might not be the right model, but I note that a repair kit for the check valve is available.

(This is not an authoritative information source or preferred supplier, just the first good diagram I found in a web search)

Never had this problem in any trailer and haven't seen it happen on the 19 as of yet. As Brian says above, the back flow is supposed to be prevented by the pump and if the tank is filling then the pump is defective. Warranty replacement or if out of warranty a new pump is in order. I wouldn't want to add a check valve as to me that would be band aid on a piece of equip that isn't functioning correctly.

Brian,
It sounds to me like you know what you're talking about. And I thank you for taking the time to craft such a complete response..

Now, what to do? I'm disappointed that when I called Escape with what then was a six month old trailer that they didn't offer more specific advice, and frankly, offer to at least help fully diagnose and fix the problem.

Meanwhile I am not that good a mechanic to feel comfortable replacing a water pump or install/repair a check valve, and not confident in the few RV repair places around here. Probably will just live with the problem. (Sigh)

Thanks again

Although these pumps are only used in RVs, the plumbing isn't really special and any plumber - or any handy person who has done a bit of plumbing - shouldn't have trouble with it. If you're not comfortable with doing your own fix that's understandable, but it shouldn't be too tough to find someone suitable. Do you know any RV owners in your area who are handy with tools?
