Water pressure really low on shore water

[Leroy]

Now this is strange. Regulator is ok, good pressure in the pump, no line
restrictions I presume? Is there a chance the Sporlan valve is leaking filling
the tank sending water to the coach and the tank simultaneously while on shore
water?

water. It works fine with the pump on. It always seems to be worse in the
morning after it has not been used for several hours. We replaced the water
pressure regulator several months ago. Removed it yesterday, tested it and it is
working correctly. Checked under the bed and that big filter has already been
abandoned. Does anybody have any other suggestions? Any help would be greatly
appreciated!
