Water line noise

[Hladerer]

I am getting noise at the water intake connection when water is running in the rig. Sound a bit like it is going thru gears or othe obstruction. Any one have any ideas? Thanks

Usually it is from the check valve inside the city water hose connection.

They are a cheap plastic plunger/spring/o-ring assembly and 'chatter'....soon after they can fail and not allow any water to flow

Do you use an elbow at the connection to hook your hose too? If not, you might be pinching the hose from the weight.

Welcome to the forum.
One way check valve stuck open?
What RV do you have? Maybe someone had the same situation as you.
