Hi Everyone. Well, after 15 years the RV-Dreams Community Forum is coming to an end. Since it began in August 2005, we've had 58 Million page views, 124,000 posts, and we've spent about $15,000 to keep this valuable resource for RVers free and open. But since we are now off the road and have settled down for the next chapter of our lives, we are taking the Forum down effective June 30, 2021. It has been a tough decision, but it is now time.


We want to thank all of our members for their participation and input over the years, and we want to especially thank those that have acted as Moderators for us during our amazing journey living and traveling in our RV and growing the RV-Dreams Family. We will be forever proud to have been founders of this Forum and to have been supported by such a wonderful community. Thank you all!!

Heat and Black Water tank

We are here in So TX.  It's averaging over 100 degrees every day.  The smell of the black water tank is horrible.  We dump every week and put in two tablets.  Any suggestions on what we should do to keep the smell down?

More water, had cyclone covers on the vents. Add extra water to bowl before flushing. I assume this odor occurs only while flushing? If not, then you need to get the seals replaced. Also, if odor is throughout your rig, how do you know it isn't the gray tank. Use baking soda liberally in both systems to help buffer the solution.

It is only when we flush!  We will add more water and maybe another tablet?  Thanks for your help.

You don't need any tablets, just water. Keep a gallon jug full and just pour extra down as you flush. Less time for doors to escape. Do you have a cyclone vane on your black tank vent? It not, get one. Really, really helps with both tanks.

Did you mean cyclone vent?  I'm not finding a cyclone vane.

Look for Cyclone vent cap. It uses a wind vane to keep the vent pointed in the right direction.

 I don't know if you are running your vent fan when flushing ... but if you do, it WILL suck stinky air into your rig.  NEVER flush with the vent fan running.

If your a/c is running it will pull odor in when flushing. Be sure to open, and close valve as quickly as possible.

 sounds like your tank is not properly vented correctly;;  Try using a liquid deodorizer   they seem to work better

as others have said DONT run fan on the out direction when flushing if yours is in the toilet area

when you dump your tank ? do u flush it real good?  is the smell worse or the same empty as when its near full

I tend to dump mine every 4-5 days in warm temps; I never get a smell from toilet but have on occasion got it coming out of roof vent

The AC recirculates inside air and does not bring in outside air so it will not suck air from the black tank when you flush.

 I disagree   if your tank vents up through the toilet when flushed which some do otherwise there would no sewer smell as  the poster claims

AC air intake will circulate this air ;; I personally have never experienced the sewer smell coming up through my toilet when flushing
