portable toilet chemical

A subject we have all seen here on the forum is odor or smell from the black water tank. A suggestion/solution to that problem that I have never seen here is adding the chemicals that they use in portable outdoor toilets that you see at outdoor events. They seem to work pretty good at controlling odor and these things are an open hole, no covers or P-traps. Wonder if this same stuff would work in RV toilets and black tanks????

  • X2! If everything is functioning properly, there cannot possibly be a smell inside the rig.

    'P' traps holding water?
    Toilet bowl seal holding water?
    Toilet floor flange good...toilet tight to floor?
    Tank vent lines clear/unobstructed?
    Air Admittance Valves functioning properly?
    Sewer fittings tight with good o-rings?

    Then no smell in rig.
    Something has to be broken in order for stink from tank to get into rig. And I'm not talking about those whiffs when flushing toilet and exhaust fan on or those whiffs that come from roof vents thru open windows when traveling.

    Dump black tank when full (or close to full)
    Rinse/flush black tank get a clear sewer adapter so you can see)
    Add few gallons of water back into black tank after dumping/rinsing bottom stays wet, stuff doesn't stick/dry out)
    Fill toilet bowl full and flush poop

    Only chemical needed is.....water

    The reason why it is not widely used by RV'ers is that the chemical used these toilets contains Formaldehyde.

    "In most states a formaldehyde (embalming fluid) based chemical is used to neutralize odors; this method of deodorizing the portable toilet has proven very effective. The formaldehyde based chemical interferes with the bacteria in portable toilets, these bacteria release odorous gas when breaking down waste. A notable exception to the formaldehyde based formula is California who has banned the use of this chemical in portable toilets."
    X-2, I use a toilet deodorizer that is environmentally safe (no formaldehyde) and use a lot of water with it.
  • Just buy an enzyme type pill or powder and add to the black and grey tank. You will never have any problems with smell or sensors not giving a true reading on your tanks. But you will never convince some of these RVers. It does cost money, and some do not like to spend it. LOL!
  • My friend was having a terrible terrible time with smell in his new fiver. I helped him out by simply adding a ton of water to his tank. Flushing.. then the smell was gone.

    If you have a bad smell in your black tank.. the answer.. is to use more water.

    Thanks!
