Low Water Pressure

2018 Thor Windsport 34R

Has never had great water pressure, neither fresh nor city hookup. My wife asked me what we had to do to get better pressure. I am thinking since its both it must be a kink in the line or some kind of blockage. I checked the water pump and it had some shreds of plastic in the filter, but would like advice on what you all would do...

First: Welcome to the Forum.
Do you have a "whole-house" filtration system?
If that filter got "junk" in it: there's no telling how much more might be stuck in there...
I'd try a fresh filter, and see what happens first.
Good luck!

run your hand all along the pex or tubing and make sure you don't have a kink

check it from the pump and from the city connection

You checked only the pump.
Take the strainers off the faucets, disconnect the shower head.

Run a considerable amount of water through the system while you check the strainers and shower head for stuff.

Replace all parts.

Spend 10 bucks on a pressure Guage to check reality vs expectation. Your 75psi home pressure is not the same as your 45psi rv Pressure.

Check water pressure.

My shower head, not the pump was clogged with plastic. My pressure was fine, the VOLUME wasn't. Two different things volume and pressure.
