Low Water Pressured

[diverdown204]

Good morning from Florida!  So, I continue to struggle with low water pressure. This 1998 Monaco Dynasty Duke (no slide) is new to me. I went to replace the filters in the coach water filter system to find that there are no actual filters in the filter holder. I have a feeling that they cause the water pressure to drop lower. This military FAMCAMP has amazing water pressure as we are very close to the water tower. So, I have it regulated down to 45psi coming in. And yet, still have pressure issues. So, my next guess is that maybe it’s the check valve.  I have cycled the city/tank water valve multiple times to loosen any debris, but still, low water pressure. I think I may need to replace the check valve. (I tried to attach a video, but it was too big.)
 

If in your experience the high pressure drop to lower pressure over about 30 seconds means something to you, please let me know!  Thank you so much for being an awesome community!

Our so called factory pressure regulator was really just a restrictor and it internally fell apart and took for ever to fill the tank. It was partially hidden behing the wet bay cover and I took it out and replaced with a real regulator.

I had pieces of debris in both the regulator and the city water selector.  When turning on an inside facet the pressure was good for a few seconds and then reduced to low flow.

 Yes, sounds like you have a restriction someplace, the system builds pressure in all the lines and in the accumulator(assuming you have one), and then drops off when the supply lines aren't allowing it to keep up.

In our '95, the rubber washer inside the tank fill valve came loose and wedged itself in the line, shutting the flow down to basically nothing.

Alrighty. Thanks everyone. Looks like it’s time to start replacing things until I find the problem. Might as well run color appropriate Pex throughout.
