We have had 3 coaches so far
- 2005 Tiffin Phaeton 40Qt
- 2006 American Eagle 45H
- 2012 American Eagle 42M
With each coaches we have had our challenges but learning to manage the smells of the tanks is always a priority for us.
Lessons we have learned:
Airflow
Depending on the coach you own, proper airflow might cause some significant smell issues in your coach. Our first coach (The Tiffin Phaeton) definitely had this issue. Believe it or not it was actually a simple fix.
By adding the White Cyclone Sewer Plumbing Vent
Proper Chemicals
There are huge opinions of what to use to properly maintain your blackwater tanks (as well as your gray water tank). We have tried most of them. Some try to kill it – Formaldehyde concept. Others try to use bacteria to eat it up.
Our findings:
Most of them don’t work.
This is the first one that seems to work very well for us
Happy Campers Organic RV Holding Tank Treatment
Expensive up front purchase but it last a LONG time. Probably cheaper than all the other ones out there.
We put 1 scoop in the Blackwater tank and 1 scoop in the grey tank and it takes it from there.
Cleansing the Tank
Our bus comes with a San-T-Flush system. It allows us to connect a host to the bus and “Flush” the black water and grey water system. We flush the system ever 3 times pumped out. We do both the Black tank and the grey tank for about 3 minutes. One thing that helps is having a Camco 39572 5″ Clear Sewer Hose Adapter
Slicking the tanks walls
Hanging out on the forums, there is a lot of discussion about “stuff” sticking to the walls of the tank causing the sensors to give erroneous errors. (1/4 full when it is really empty). We have had heard several solutions to this problem.
- Bath Beads with a bag of ice
- Borax
- Bleach (No Way)
(Updated 5/31/16)
After extensive testing with all 3 and also with Calgon Liquid Water softener we are now convinced that Borax does the best job of cleaning the sides of the tank as it is going down the road. We had 3 full-timing friends as well as a company that cleans out tanks suggest that this stuff works wonders (and it does)
What we do is take 1 cup of Borax and add it to the Grey Tank and Black tank and put it in a tank with 1/2 full of clean water.
Then we go on a drive to our next stop…
The slushing around clears the walls well. We then empty the tank once we get there.
Is this better than other ideas? Not sure but it works, very well for us
What do you do?

Just Borax? No Dawn?
Martha – Correct just Borax and a lot of water in the tanks (at least 1/2). We have a lot of full-timer friends doing this and there tanks stay very clean and there sensors always work. It may take a couple of times if it is bad problem. We had our tanks pressure washed and the person who did it told me the cleanest takes they have seen have always been the people who use Borax. The Dawn can generate a lot of soap suds and potentially residue.
