pump sends water out external hookup

[jacks5canada]

I have just purchased a 2007 shamrock hybrid. When I turn on the water pump the water shoots out the external hookup - even blows the cap off (doesn't fit great). My understanding is that there should be a valve that does not allow water to flow in the wrong direction to the external hookup but i don't see where it would be. I had a hookup for a filter but no filter so I just got a piece of hose to bypass. I have attached a photo of the plumbing system: the blue hose going out the top goes directly to the external hookup - nothing in between.

Any help is appreciated!

Your city water inlet check valve is stuck

Thanks - I do not see where one is - there does not seem to be any valve between the pump and the city water inlet. There is a T on the line but it does not seem to be a valve. What does it look like and how do I unstick it?

It may (should) be part of the city water connection. If you remove that fitting from the outside or inside, you should see an extra thick fitting. That would be the check valve. You should be able to find one at most hardware stores and fix it easily.
at least that is how mine is

when you hook up a water hose to the inlet - does the water work ok?

I got this snip it from another site:

Concerning check valves, typically you’ll end up with three fresh water check valves; one at the cold inlet to the water heater, one at the city water inlet and one located at the outlet of the water pump. When on city water, you’ll want to keep water from entering the pump and when operating the water pump, you want to keep the water from spewing out the city water inlet. I always recommend carrying a spare backflow check valve just in case.

Below is what a metal and a plastic check valve will look like and there are other types as well

The check valve is attached to the city water inlet. You will need to remove the inlet and replace with a new one. I had the same problem last year. It is an easy fix.

The rubber stopper had a filter on it shaped like a bowl, it was hitting the valve and causing the city water to be always open....easy fix when I reversed the stopper!

Could these check valves effect water pressure inside, like shower sinks??

Our check valve was not working properly and we had low pressure in the trailer. replaced valve and now have great pressure.
