Generally, on fifth wheels, the fresh water tank is in the rear area of the rv, but the pump is usually up near the front near the rest of the plumbing. Ie water heater, bathroom, etc. There are storage areas in the front, usually, the pump is on the side where the door for entering the trailer is. Open the storage access door that is on that side in the front and look at the panels that close off tbe storage area to the living quarters of the rv. There is usually a hole for access to a “winterizing point” marked. There us where you will find the pump

Contact your local Forest River dealer or directly here: Forest River RV Contact Us Forest River Inc

Go to the water heater manufacturers website and download the installation or service manuals

Contact the manufacturer of the coach for their owners manual. However, each appliance will have a separate owners manual form its perspective manufacturer, i.e., Water Heater = Suburban, A/C = Dometic, Refrigerator = Norcold, etc.. There will not be a diagram of electrical or plumbing as a majority of the RV manufacturers do not publish that information.

Replace the water? Is there more to the question?
