Now that is a great idea.

I have the same issue with my 2015 Columbus. I must say the plastic tape makes a lot of sense. I think this tape is closest to the hot water tank and would get hotter water. I’ll try changing out the tapes as well.

Not so, it's only from the hot water side.

Look, Bruce (Nomad297) is a master plumber. He knows what he is talking about. In this post he told you that the plastic faucet (or possibly the woven flex hose, if present) is deteriorating due to the very hot water. Believe him.

If you are wondering why it's only one faucet, it could be that it's the faucet closest to the heater--or it's a different material than the others.

I guess I should have specified "hot water tank"

Anyway it can not be the hot water tank causing the problem as Flybob figures, because the smell would be at every faucet not just the bathroom.

What B & B said, # 16. Had a Cardinal for years and dealt w/the same issue. Washer & dryer area was used for storage and the water lines in that area had antifreeze in them and caused the exact same issue. Cleared the lines of the aged antifreeze, sanitized and the smell was gone.

What benefit will I get from doing that?

[drrmwall]

It might be from the deteriorating plastic. I will check that thanks for the info. But i don't have a washer hook up so i know its not that. I will replace supply line then faucet thanks again

I didn't see this touched on here, so something to rule out.
First, I'll emphasize that this is likely NOT the culprit, but...

You said "sewer" smell.
If your drain "insta vent" is bad, there is a slim but real chance that hot water is provoking more odor than cold water. Depending on where the grey tank is for the bathroom...very likely right under the bathtub...you may be "activating" the bacteria in the grey tank a bit more with hot than cold.

While you're doing all the other steps, you might want to add a new one. If yours is glued in, get a glue-on female pipe end so you can swap out to a new threaded version when needed.

Both are illustrations, not particularly recommendation, although Oatey is usually a good product.

Thanks for the info. but the smell isn't coming from the drain it is the water if i put the water in a glass the water smells

I had this happen in my keystone challenger. It was only in the bathroom hot water. I found my problem was algea growing in the water line i flipped my valves acted like I was going to winterize but instead of rv antifreeze I pumped the whole trailer full of a water bleach solution, let it sit for an hour or so and flushed the whole system with clean water. My lines were the translucent white lines not the blue and red pex so I was able to put a flashlight to them and see the algea and was able to see the bleach kill everything in the lines after i flushed the system the smell was gone. Hope this helps you.

I had this problem all last year. Only the hot water side of the bathroom faucet when we were on city water, nowhere else.


I tried chlorine bleach through entire plumbing system: didn't fix it.


I tried the brewer's sanitizer (the pink stuff) in the entire system: didn't fix it.


I then used Star Brite 32300 Aqua Clean Water Tank Flush (about $30 on Amazon) this spring. It took about 90 minutes to do all the pumping in and then flushing it out.



We've been out a few times this year and NO MORE SMELL IN THE BATHROOM SINK!!!

Had a similar problem. Issues was:
I have the lines for clothes washer T off the sink lines. Since I don’t have a washer the lines never get a bleach water through them.
Once I cleaned the lines the smell went away.

My FR GT5 is doing the same thing sight now. My hot water in the bathroom sink is the only one that smells. The kitchen and shower hot water doesn’t smell. Puzzled !

The common source of smelly water is the water heater. Anaerobic bacteria that naturally occur in water can react with the magnesium and aluminum anodes to produce hydrogen sulfide gas (rotten egg odor).

Chlorine bleach can effectively remove the hydrogen sulfide and provide a side benefit of disinfecting the water supply.

Before I connect my 5th wheel to the campground water supply I "carefully" add one tablespoon of full concentration bleach into the female end of the hose. Then, I vent and flush the hot water lines first. After two or three treatments the odor disappears and continued treatment every time I change campgrounds keeps the water fresh smelling for the entire trip.

Thanks I’ll try that and hope that’ll do it.

This is not the solution when the smell is at just one faucet.
