Setting up RV to use water pump instead of Park Supply

Did you check the water hose for an obstruction?
We had low water pressure when we first got here.
We managed for a few days by simply turning the water pump on to augment the city water pressure. The plumber located a large clump of grass clippings in the hose trap at the faucet. After that we had great water pressure. Thankfully I had that little screen in my hose. Now the first thing I will do is to open the faucet for a few seconds prior to hooking up the city water hose... :B
