Bathroom Smell

Any tips for eliminating the odor in a bathroom. I had my tank all flushed out and follow all the rules on water and tank chemicals but still get an odor. I also put those air wicks on the counter but it doesn't eliminate it.

    This it often the cause of such odors, and in fact coming from the grey tank. There is typically an "auto vent" near the sink, the lav(s) and washer area. Even if your rig is plumbed for a washer and does not have one, it may still have an auto vent in place for it.

    They do go bad over time and let air from the tank back into the RV. You can get them at any home improvement retailer.



    Is that the part that's on top of the pipe?

  • Check your seals and ensure you have a good bowl seal of water when opening the trap quickly. We did 5 days this weekend without chemicals and were fine. We have ALWAYS used chemicals prior but read of many saying they are not necessary provided we had good seals, it held water and we kind of caused a seal with the water as we opened and flushed quick. Worked like a charm and no odour all weekend. Proved to us we can operate without chemicals which at the end of the day only mask over the smell but it's still kind of there underlying when using chemicals or air freshers anyway.
