Water Hookup and Water Pump Problems

This is a simplified drawing of the water system in a typical trailer.

Maybe this will help understand how the water flow works...

Thank you all for your suggestions.

For some reason your system is not pressurizing itself. Start at the connection (your water pump shouldn't be on) and then check all fittings. Mine usually squeals a few seconds than stops.

I had problems with getting ANY type of water thru my system after I installed a whole system water filter. I installed the filter canister without the filter cartridge and then sanitized the whole system and completed a system flush to remove the bleach. Everything worked perfectly until I installed the filter cartridge. My pump caveated and squealed and produced NO water. Further inspection resulted with me finding that I had the filter cartridge in backwards. I fixed my mistake and have had no issues to date with the water pump system. The pump squealing noise you hear is the pump “starving” for supply water. Something in your system is causing the water to NOT flow freely. Start from the main water supply and work toward your pump and beyond if necessary. The restriction should identify it’s self at the point where you have no more water or a visible reduction in water supply. Hope this helps.

Agree ^^^^^
The squealing noise & low water pressure is from a faulty inlet check valve on 'city water' connection

The rapid fire pump cycling......pull the aerators on faucets and check for plugging.
Run pump with aerators removed, check pump action & flow

Sounds like a bad check valve at the city water connection. My guess anyhow.
