Zulu Posted July 6, 2020 Report Share Posted July 6, 2020 Turned my water pump off. Filled up my water tank and left my RV's water intake valve open to the park's system. Then I turned my water pump back on so I have the option of choosing between park water or RV tank water at the flick of a switch. That's worked fine until today. After I while I noticed my RV water pump pumping away, but we weren't using the sink, toilet, washer, etc. When I checked my water tank level, it was two-thirds empty. Where'd the water go? I noticed that when I closed my RV's water intake valve, my water pump stopped. So apparently I had been pumping my water tank into the campground system. I've had this happen at another park when the backflow valve failed on the water spigot I was connected to. However, in that case my water tank emptied on the ground near the spigot. Is this another case of a failed backflow valve?

If it's not working properly, when you take the city line off and run the pump, you would be spraying water back out of your city water inlet.

It would indicate that the city water supply has a very low supply pressure if you are able to pump water from the tank to the city system. Most RV park hydrants have a back flow preventer on the hydrant and in most cases are required to have that. In addition, the city water connection should also have a check valve in it to prevent that from happening. In this case, both would have to fail or be missing. The first is what is typically found on a city water hydrant, the second is a typical RV fitting. There are several different styles of each of them. An easy way to see if water is going into the city supply is to just turn it off at the hydrant, leaving everything connected as it is. If that is where the water is going the pump should quickly stop. Edited July 6, 2020 by Kirk W Quote Good travelin !...............KirkFull-time 11+ years......

Twotoes Posted July 6, 2020 Report Share Posted July 6, 2020 When you fill your tank with fresh water you turn your intake valve to fill. When you are done filling your fresh water tank you should turn the valve back to to city water. Only turn on your pump when you are not hooked up to city water and are running off your fresh water tank.

We will, on occasion, turn our onboard pump on(we make sure there is water in the tank) to get a higher flow from the existing cg hookup especially if the CG is full.

I agree with twotoes. I always close the city water faucet when the pump is on, otherwise if the back-flow prevention device fails, I just contaminated the CG water distribution system.

I believe campground's are required to have back flow preventers and to periodically check them. On my side, it was an easy fix (Camco 23402). However, campgrounds are responsible for keeping their back-flow preventers operating. Also, I would guess there are a whole bunch of RVers who know little if nothing about campground electrical issues (low voltage, open grounds, etc.).
