Mineral deposits and sediment collect in the bottom of the water heater tank and the only way to remove the deposits and thoroughly clean the tank is to flush it. I recommend flushing the water heater tank twice a year at a minimum. Here is how you do it.
Turn the water supply coming into the RV off. If the water heater was on, allow time for the tank to cool. Never drain the water heater tank when the water is hot or under pressure. Relieve the pressure by opening a hot water faucet in the RV. Remove the drain plug, or the anode rod if it is a Suburban water heater. You can open the pressure relief valve at the top of the water heater to assist in draining the tank.
You can purchase a flushing tool designed specifically for this job. Connect the flushing tool to a water hose used for maintenance and turn the water on.
Place the tool in the water tank drain and open the valve on the tool to flush the sediment from the sides and bottom of the tank. Continue to flush the tank for several minutes. When the water coming out is clean and clear you can stop flushing.
Reinstall the drain plug or anode rod. These are preventive maintenance steps the RV owner can perform to keep the water heater in top operating condition. If there are other problems with the water heater you should have it checked by a qualified RV service facility.
Now the RV water heater is ready for the next camping trip.
