We took out Camper out for the 2nd time and had to use out fresh water tank since there were no water hookups. My question is the pump made a racket when it kicked on, is that normal for a pump in an RV?
It will make some noise. Usually more if it has to pump empty lines. Just make sure to turn all your taps on when you are filling up so that the lines pressurize. Once the air stops and it’s just water then turn them off. Also remember to allow water into hot water tank when filling up so that your hot water and fresh water both are full before you set up.
Pumps are often mounted poorly on a thin board, you might want use use a thicker piece of plywood for mounting, or go the other way and use foam like a kneeling pad. Rigid pipes may be banging into the wall or each other, add foam pipe insulation wherever the pipes touch anything. Adding 3 foot long flexible hose to each side of the pump will help, a kit is available for that purpose. Adding an accumulator will reduce pump cycling and also reduce noise.
Like lynnmor said the pump is probably not installed correctly. Depending on the pump, it might have 4 rubber feet that are supposed to absorb vibrations. A decent mounting surface is required with some type of vibration absorber. Ensure that the lines going into and out of the pump are flexible and not rigid. The pump does need to vibrate when it runs - hence the mounting. Just a couple of things to consider, but my guess goes to the mounting. Find the manual and see what it says.
