Hello, I recently bought this truck camper and when I hook it to the city water the potable tank is filling up. I've looked for a valve to turn or a check valve and have not found either. I do...

Hello and good evening Bosun
Truck Campers usually have 3 check valves in the water system.
1: City Water Fill
You cannot see it but its there to stop water from coming out of that device when you are using on board water. Your water pump is drawing off your fresh water tank and pressurizing your entire R/V. That Check Valve stops the water from leaking out that city water fill
2: Water heater (Discharge side-hot water coming out of the tank)
It looks like a 2" plastic nipple coming out of the hot water side of your water tank. Its internals consists of a spring and plastic ball.Its put there to stop the back flow of anti/freeze when you are winterizing and putting in that pink stuff. If it was not there, you would be pumping 5 gallons of anti-freeze inside your water heater.
Now saying that there are some MFG who opted for basic shut off valves and you maybe not have a check valve!!
But based on your comment of the lack of water pressure, my vote is yes you do have a check valve
3: 12 volt Water Pump
Its part of the water pump assembly to stop water from back filling into your fresh water tank
A) You have a bad check valve in your water pump - Replace the entire unit
b) You have calcium build up in that check valve on the discharge side (Hot) of your water heater. Replace with a brass check valve
