When hook up city water to rv it shoots out vent
It is likely one of two things, either your RV has a waterline to your fresh water tank that allows you to fill that tank when you are hooked to City water, or the check valve on your water pump is bad and it is allowing city water to fill your fresh water tank. Make sure your freshwater tank is empty, have someone turn the city water on while you watch the freshwater tank... you should be able to see where it is filling from....if it is filling from the water line that run to the water pump, the check valve is bad, if it is filling from a city water fill line, locate the valve on that line and close it. If it is indeed the water pump check valve...you can either replace the pump, or add a cheap inline check valve, like a sharkbite check valve.. they run like 12 to 15 dollars.. install in seconds....you just cut the pex pipe then shove the ends into each end of the check valve.
