I've loaned my Dolphin to my niece and her husband who are staying for a week at a nearby RV park. I've had problems in the past with the built-in regulator shutting off water flow when the park pressure is too high, so I use one of those cheap junk regulators at the hose bib whenever I have a pressure problem and that has worked for us, though it cuts the pressure a bit too much. My niece texted me this morning saying that they have to run the pump to get water. Fortunately, I filled the water tank for them ahead of time, but I'd like to fix the internal regulator, which I suspect is the source of my problem. I understand it's on the water bay panel and is part of the inlet.

My question is, how big a job is it to replace this internal regulator and does anyone know of a drop-in replacement? I'd be ok with removing it entirely and putting a regulator on the hose bib when needed. TIA!

EDIT: Is this what I need?

Yes, that is exactly what you need. I have replaced mine several times. Not because of a loss of water pressure, but they will leak through the housing after a while. You have to pull the panel to get to the plumbing on the back side. It is not hard to do. I replaced some of the hard pex line with braided flex line to make it easier.

Thanks, Fred! I'll get one on order and get it changed out. I was wondering about how flexible the lines would be behind the panel, but I guess pex line will at least be a little easier to deal with than PVC.

Actually, I think my coach has this one. Discontinued, but still available on E-Bay for thirty-some dollars. Would like to find it in a 65 psi version.

The are available on Amazon https://www.amazon.com/gp/product/B00074QUDU/ I bought an extra one, as well as a spare water pump. Cheers!

Thank you for the response. Yes, that's the same one I linked to in my first post. I didn't remember mine having the wide collar around the inlet, but I went by the moho yesterday and in fact that is the one I need.
