Water Heater flushing

All,
My camper is in its sixth year of operation. I would like to flush out the sediment that has collected at the bottom of the water heater. Have you found a reasonable (time) or possible way to accomplish this?
Thank you for the help!
  • Connect your rig connected to city water. Higher pressure the better.
    Take the plug out of the tank and turn the water on,when the tank is cold. It'll just about know every thing loose in the tank out.
    Use the little wand from CW and see if anything else comes out. Tank is aluminum so watch the vinegar.

    Cut and paste into your URL. For some odd reason I can't make a clicky out of it for you. Kirk does an excellent job on teaching RV maintenance.

    ON EDIT.

    It appears the cut and past won't work either. Go to this Clicky and, follow the drop downs to the water heater page. Very good way of cleaning the tank.
  • Frequent flushing works great, but if you think you have some built-up mineral deposits you can after flushing also put a couple of gallons of white vinegar in the tank through the port where the pressure relief valve goes and allow it to soak for a while and flush the tank again…
  • If it's a Suburban water heater, go buy a new anode rod to replace at the same time.
  • With your taps inside and out all shut tight, and the safety valve not opened either, when you take the plug or anode out the water should just gurgle out. I have used a toothbrush through the hole as it's gurgling to stir up the sediment and cleaned it out pretty good. Also putting a wand onto your hose, soft plastic would be good, and putting it in through the drain hole while running water into it.

    A lot of the sediment comes from the anode. If you don't have an anode, likely there will be very little inside to worry about.
  • I flush mine every fall using a wand to go inside the drain hole. A 6 year accumulation may be hard to remove.
