How to Install a Water Tank in an RV
A water tank in an RV holds the fresh water used in the sinks, shower, toilet and maybe an ice-maker. It needs to be located somewhere where it can easily be hooked up to the fresh-water lines in the RV. The RV will have a spot specifically designed to hold the appropriate tank. The water must be pressurized with a water pump installed, per manufacturer's instructions, between the RV plumbing and the tank. There are many different types and manufacturers of tanks and pumps, so find out what size and configuration you will need and follow the individual instructions as required.
