It was just one possibility that was suggested. I don't think it's necessarily a likely culprit either. Problem is there just doesn't seem to be any good explanation and the anode, if it can be removed, is pretty easy to rule out.
n is that they encourage bacteria growth which releases hydrogen sulfide. I've never seen it happen myself. My inlaw's water has that smell, bu t it's from a well, and in both the hot and cold water. The hot water is worse of course because it volatilizes. But while I haven't seen it, th ere are lots of articles that say it happens.
Agree, that's my understanding too.
only a tiny amount dissolved in water, it just happens to affect our nose v ery easily. If it were concentrated enough to burp at a faucet, it proba bly would be enough to kill you. For sure it would corrode anything near by, probably eat through pipes.
I agree. I don't have an explanation for what possible chemistry could account for a reaction at the anode. Here is another thought. What happens if you have a bad electric heating element that has the electric element in contact with the water? That would produce oxygen and hydrogen. Maybe that is more likely than some kind of reaction at the anode. Might be worth seeing if air shows up with the tank turned off.
Well, long ago there was a report of hydrogen in a water heater, but I t racked down the original report and it turned out to be something else, lon g story.
as air. Does it smell at all? Will it burn?
I would think any gas that's observed, absent anything unusual, would be reported as air, because that's what we tend to think of as "trapped" in a water system.
t's making enough gas to burp, I'm not sure I'd want to drink it. Must b e like jello inside, with that much bacteria.
e water supply. You actually have air in both hot and cold water pipes. BUT, you never notice it in cold water for two reasons. Cold water di ssolves more air, and your cold water pipe layout has some areas where it g ets trapped. Your hot water tank has a dip tube for cold water entry, bu t hot water leaves through the top. Your water sits in the tank long eno ugh for air to separate and form a layer on top of the water.
Something like that is theoretically possible, I guess.
ly screwed in really tight. And even if you get a shorter one or segment ed one, you still need clearance to get the old one out. I wouldn't try this except as a last resort.
The anode should come right out of a new tank. I got mine unscrewed on a 5 year old tank without anything special. If it's 15 years old, that could be a whole different thing.
