Water pressure inside rig

[e.menoche]

Having very low water pressure inside rig at all locations, bathroom faucet, shower, toilet, and most noticeably, at kitchen sink. Rig uses the nautilus water panel. Looking for advice, but consider the following:
1. campground water pressure is fine. Plenty of water flowing from supply hose after pressure regulator.
2. pressure is equally poor whether on pump or city
3. system pumps and fills 80 gal fresh water tank in about 25 minutes--normal
4. water panel is brand new
4. water inlet/check valve on new panel has been replaced
5. running the pump causes the back check valve to jam in the back check position. It will only release with help, and then water shoots out under considerable pressure. After release, back check valve moves freely against the spring.

Given the foregoing, any suggestions as to why internal pressure is low?

You didn't mentions filter(s).

Oh yes! I removed the filter and tried the pressure. No change. Then put a new filter in, which I needed to do anyway, and still no change.

And I also forgot to mention that I soaked the aerator for the kitchen sink overnight in vinegar.

There is a very big difference between static system pressure and lowered pressure during flow through inlet screens, valve bodies, elbows, pressure reducing devices, etc.

I too experience a less than stellar pressure unless shoreline is high.

At 55-60 lbs my shower is fine, the bathroom sink is ok, but the kitchen sink is not very good. I think it is the design of the faucet. I changed it out a few years back and it did not help.

I'm convinced there is an over zealous check ball valve somewhere along the system that will open fully when the pressure gets to a pressure that will overcome it.

I have had to change two check valves over the years and cannot remember when this annoyance occurred.

Following this I hope to pick up some tips. It is a pain chasing those pesky check valves.

It might turn out to be a perfectly normal thing on my sink. Conserving water while boondocking can be critical of course. We full time and I would like some increase in pressure in the kitchen.

The shower has one of those oxy whatever shower heads and works well.

As the op mentioned, turning on the pump does not really help.

To also add some perhaps useless information, upon flushing our toilet, while it fills the pressure anywhere goes very very low. So that might be a useful diagnosis tool.

Well, yes, I am at home. Fulltiming for 5+ years. The water pressure issue we are having is not normal.
