Water inlet check valve

the check valve wasnt working where you connect the water hose so i remove the check valve so i could get good water pressure. then i notice when i didnt have the water hose conected and i turn my holding tank pump on it would pump water out of the water inlet where you connect the hose to. is that correct? does that mean i have to put a check valve back so when i use my holding tank pump it wont pump the water out?

Thanks for you help

You are correct in your thinking Dennis, that check valve/valve needs to be in there. Is the parks pressure low? There should be a sealed cap on the inlet when not in use. If you leave the check valve out, and when you are hooked up to city water, and you turn your water pump on, if the pumps pressure is greater than the parks pressure, you will pump the tank empty. Best to reinstall it.

Check valve in city water connection and a check valve internal of pump so that water doesn't leak out of city water connection when running pump and doesn't overfill fresh water tank when on city water by backflowing thru pump

Those check valves in city water connection are JUNK......nothing but a plastic plunger/spring/O-ring assembly

Get O-ring out of it's grove and water is restricted/leaks
Plunger gets cockeyed and water is restricted/leaks

I gutted mine........installed a garden hose shut off valve. (Angle & straight at any hardware store)


OR

You can just screw a 3/4" PVC plug in city water connection when not using it.

Surely you meant the pump to/from your fresh water tank and not your "holding tank"--tell me its not so [smile]....

That value, if it is one you connect your fill hose to, is also a pressure protection valve. It protects the house hoses if you were to hook up to unregulated water source. One it has "popped" you (going of memory) open the valve up, there is a part that looks like an umbrella, pull it back and it will snap into place. Basically, when over pressure happens, the "umbrella" snaps loose and plugs the inlet.
Vary simple but important part of the system.
Easy fix.

Water inlet check valve

You really should replace the check valve, in the event you forget to shut the valve, or more likely did not close it completely, you will pump your fresh water tank dry, and only have low water pressure within the coach until it runs dry.

If I have low pressure at a CG I turn on the pump it will increase the pressure within the coach. It also depletes your fresh water tank but you can refill that when you do not need water pressure within the coach.

Exactly what I do Dave.........
I have them, and never had a pressure/volume problem, other than the parks pressure, and I can see that on my gauge.
