Foamy hot water?

[RzRzRzR]

We have clear cold water and foamy hot water. Slight rotten egg smell when hot but not cold. Hooked up to campground water right now. Video below. Any ideas?

I would drain your water heater, flush it and see if your anode rod needs replacing.

As the anode rod sacrifices, salts are precipitated in your water heater, tending to collect on the bottom then stirred up in response to water demand. This is aggravated
by hard water and sediment from the street tap.

I drain and check after every trip, at least every quarter. I use one of those little flushing nozzles and the milky, sediment water never fails to come out. And to a certain extent, there will be a little attendant foaming action. Not like soap, but there nonetheless.

Good Luck

Terry has the right idea. Also, you have instructions in your owners bag for sanitizing your system. I put the bleach in the water filter cup with the filter removed. I fill my holding tank with this solution and then run from the tank. Run the hot water till you smell the bleach. Let it set for a while and then drain the fresh tank. Run, city or tank, fresh water through your system until the bleach is out.


When you drain the hot water tank make certain the power to it is off. The heater coil will burn up if not submerged when on. Not all tanks have scavenger rods.

Most likely stuff growing in the tank. I just flushed our system, had foamy hot water. Filled the water heater, using the pump, from the bleach solution in the fresh water tank. Drained the water heater and white gooey globs came out. Then hooked up the hose, with the drain plug on the heater removed, and turned on the hose. That blew more stuff out and the foamy water stopped after that.
