Setting up RV to use water pump instead of Park Supply

Followup:
My solution has worked well for the last 2 days, so I am good for now.

I bought a pressure gage and checked other spots in the resort, they were all between 40 and 45, so it is not just my water supply

I talked to a couple who own a home in a subdiv. next door and they said their water pressure is low as well.

I called the water company and they said they have not reduced the water pressure. Some how I just don't think they are telling the truth.
