Holding tanks

Has anyone heard of putting fabric softener in the tanks for odor control. someone told me he uses it and his tanks never stink? TOM
  • How long does it take for water softener to "build up". I have used it for 30 or so years, first at home and then in the camper, with no build up. Just wondering.
  • I've tried many things. What i found best dump, rinse ,fill and soak for several hours or longer if possible. Dump, fill , dump and rinse. Do this at least once a week.
  • Like Barbara said the waste system is sealed except for the roof vent/s. If you have odor that isn't coming from sewer gas being drawn into the RV somehow, you have a problem that needs to be addressed.

    Waste tanks stink no matter what you put into them. To me perfumed poop still smells as bad as poop.

    There are a lot of out here that use nothing but water and have no odor problems, In my case 11 years of full timing with no odor problems.

    Some things to check:
    Water in all traps,including washer if you have one.
    Air admittance valves on all sinks sealing after dumping.
    Roof vents not clogged with wasp nests

    I'll second WATER. Why, oh why, won't people listen and USE WATER? As to odor, if the toilet seal is working there shouldn't be any odor unless you are flushing with the bathroom exhaust fan running right above the toilet. Flush, make sure water is in the bowl, THEN run the fan.

    How did you manage to miss West Virginia? You missed a beautiful state with great parks.

    I know, it kind of sticks out. Hopefully we will get it this year. Not really sure why we've never been through.

    You might not smell the poop, but your neighbor and many others in the park do when you dump. That is not necessary if you cared about your neighbors, just invest in a enzyme type additive to your tanks where the solids will be broken down, and you will not have any smell or very little. I have seen some in RV parks that when they dump, they stink up the whole park. That is not necessary.
  • Tom, something else that I do is after I dump and close all the valves then add 1/4 cup Dawn and pour in 5 gallons of water. The soapy water slushing around while your traveling will really clean the holding tank. I also have the luxury of having a built in oscillator system in my tanks this cleans my tanks and my sensors. If a person has caked up material they should buy what Ray Chez, suggested in his post. I use an enviromental safe deodorizer for smells.
