Help Vegas City Water

[Scubawise]

Pump hot cold water pressure is fine. Hooked up city water and hot & cold significantly reduced flow.
Checked flow at campsite spigot and massive flow.
Ordered pressure gauge that can be set coming Friday then I can officially test. Took off bedroom draw no leaks. Shower toilet kitchen bath faucets reduced flow.
Here are pictures with and without strainer.
No sure what else to look at??

Starting this season, I'm not using city water connection. I'll fill the freshwater tank and use the MH pump.

My thinking is the pressure is ALWAYS what I expect. No worries about turning off city water when away... just the pump.

Even though I have always used an adjustable regulator, it's just one less complication, and one less thing to go wrong.

SO... about your issue. Is your city water connection on a slide out wall? If so, the inside plumbing connection will be a flexible hose... so it can move with the slide. Ours is accessed under the rearmost dinette seat... unscrew the plywood cover. Check that the flexible hose isn't pinched or kinked.

Not in slide. Need regulator coming Friday to test
