If it's been awhile then definitely drain the water heater. Replace the anode rod if your model uses one.

And flush! Maybe even descale it.

I used to use bleach, now I just use captian Phab purge tank cleaner. works great, and no massive rincing to get the extra bleach flavor out.

Most sources note a minimum of 6 hrs for 1/4 cup to 15 gal. You can speed it up by going to 1/2 cup for 3 hrs. Do NOT do more. Gotta give the bleach time to kill whatever it is gonna kill.

You can just run the faucets to flush the water heater, but it takes forever, since the fresh is slowly diluting gallons of bleach water in the heater. Much faster to pull the plug, and drain all the bleach water, then refill. Then all you have to worry about is the much lesser amount actually in the lines.

Yes, the concentration is low enough, it will not hurt grass or any other surface you dump it on.

Almost all city water is treated so that most of the chlorine is used up by the time it gets to your tap. There may be a little, but not enough to do any sanitizing on its own.

I pretty much do as most here leave it sit for a day. I then used the pump to empty the FW tank allowing it to run into the gray and black tanks. I then add baking soda to the fresh tank and fill again. Pump this mixture thru until bleach smell lessens and can leave it in the system for use after that. Kinda have a problem wasting more water than needed. I may leave the water in the gray and black tanks for a couple days then empty them.

I added a tee & drain valve to my water heater, much easier to drain now!

Thanks for those answers. One more question - Is it best to drain the water heater after the sanitization, or is it ok just to leave the faucet open and pump fresh water through until the bleach smell goes away?


Pumping fresh water into the tank will only keep diluting the sanitation bleach water and really purge it. IMO it's best to drain the tank completely and refill with fresh water.

I have looked for this product and cannot find it. I have found holding tank treatment but nothing that goes by this name. Can you provide a link. Thanks!

I open my low point drains and burp the pressure relief valve on my water heater, almost every trip. That completely drains the lines and water heater.

We did that after a year that my wife got sick in the beginning of the camping season and we ended up parking the camper for 6 months. We had gotten water at a campground with a well and ended up with sulphur smelling pipes and water heater. Had to bleach and run baking soda through the lines to clear up the smell.

Never again. Drain almost every trip.

Google: captain Phab purge tank cleaner

or click

I see nothing about the product killing bacteria, only removing scum that might support it. I would use bleach after using that product.
