This is a heartland elkridge ultimate 37. Sink is in bathroom. Does have an unused washer/dryer prep work in bedroom. Vent cap for washer prep is sealed. Smell only occurs with showers and tank more than half full.

Thank you. We are currently on a trip so was trying to avoid taking it in or at least pointing them in right direction to help resolve quickly. It is a heartland elk ridge ultimate 37. Sink is not in bedroom, but an unused washer/dryer prep is. Cap for drainage on prep is sealed. It only occurs during showers with tank more than half full. No other times. Thanks again.

I wonder if the problem is the vent pipe is too low in the gray tank, and when half full the vent pipe is full of water, which would cause the odor to build up and then release when the water is flowing in the trap.

Very good possibility......

IF vent line is getting blocked the fumes have to go somewhere when additional water is added to grey tank as could flow back up shower drain as it is being used.
Then smell goes away when grey tank is drained.....vent pipe no longer under water/blocked.

The other possibility is the battery off gassing from overcharging.
Easy to eliminate...check battery water level, any bulging of battery case and if the case is hot.

If battery checks good..........then that vent pipe is suspect.
The vent line problem will need to be corrected. Line slipped down into tank to far.......dealer fix as it might need to have tank removed to reposition & properly secure vent line.


Is it time for your medication or mine?

This is all helpful. Question. Would battery overcharging have any correlation to showering? That is the only time it occurs.

X2, smell under the bathroom sink if it smells there you need a new air admittance valve aka vacuum breaker.

Check the air admittance valve that is likely located under the bathroom sink. If this fails to close properly it will let odors from the grey tank enter the living space. This is a vry inexpensive device available from any home improvement store for $10 or less.

On my washer dryer prep there is a air admittance valve near the washer P Trap. That would let odor in the bedroom area.

Our 5th wheel had a strong smell when using the shower with the exhaust fan on. Turns out the vent pipe was not seated all the way in the cap on the roof. I sealed it with some putty and the odor stopped.

Just a wag but does your water heater have an sacrificial aneroid? They can smell just like you describe and could be source of smell during a shower.

Smells can be a stinker to track down!

good luck

I also think that this is caused by the hot water heater.
