It's a Valterra adjustable lead free regulator preset to 45 psi. I haven't changed that.
I am not sure what these regulators looks like inside and have not been able to find a drawing or design info. on the internet. Your regulator could have a build-up of silt or deposits inside. If the
Valterra can't be dismantled and cleaned, it's time for a new one. In that case, I would upgrade to a better Watts or maybe Cash Acme.
That's a good suggestion to borrow someone else's regulator and see what happens.
Not much info. out there from RV users on the Valterra adjustable regulator. These threads might have something in them for you.
