We demonstrate how to thoroughly flush and clean an RV hot water heater. Rust, lime scale and other debris can build up in the hot water tank on your motorhome, travel trailer or 5th wheel. Left alone, this can shorten the useful life of your hot water heater. Simple annual maintenance and care of your RVs hot water system will save you money by extending the life of the heater. We recently flushed the Suburban hot water heater on our Newmar, so rather than do it again, weve borrowed our friends Atwood water heater to demonstrate how to do it. Only a few simple items are required, including a wrench to remove the drain plug or anode rod, a tank flush wand, and some white vinegar (12 gallon for every gallon of tank capacity). If you have a Suburban brand water heater, be sure to have a new replacement anode rod on hand as well (magnesium, aluminum or zincaluminum). The small amount of time required to do this simple but essential maintenance will pay for itself with years of extra service from your RVs hot water heater. Be sure to confirm that all methods and materials used are compatible with your particular RV. RV Geeks offers basic DIY (do it yourself) RV service, repair and maintenance tips from full-time RVers who have been handling most of their own maintenance since hitting the road in 2003.
