Pumping out sanitizing bleach

[IBEW Sparky]

No one seemed to mention to also avoid getting any bleach solution in the toilet and black water tank.... it's not good for your toilet seals or the black tank due to killing off good bacteria in the tank.

The concentration is so low (if mixed per the manual), it won't hurt the toilet seals. At all. While there will be bacteria in the black tank, it is just a holding tank, not at all a septic system, so it doesn't matter if they get killed. Might even help a bit with any nasty odors. AND - even if you dump into a real septic system (a home or campground not on a municipal sewer system), it not only gets very diluted by the liquids in the system, the vast amount of organics very quickly neutralize it. Actually, the organics (poo and paper) still in the holding tank already likely have done a pretty good job of neutralizing it before it gets to the real septic system. But I have never use my testing kit on that, or gotten my nose close enough to sniff it, to see....

The key thing to remember - more is not better. 1/4 cup per 16 gallons is a safe amount, some sources go as high as 1/4 cup per 12.5 (ie 1 cup for a 50 gal tank). Let it do its job for 4-6 hrs. Then dump and rinse.
Just like acids, it is all about the concentration as to whether it is helpful or harmful.

Cannot run it in tankless that use copper tube.

I don't know why people still even use nasty bleach to sanitize their water lines and tank. Bleach is just nasty stuff, not real easy to completely remove and rinse and corrosive to many metals that it may come in contact with. Use BTF Idaphor or star san. Two proven sanitizers that are used in the beer and wine making industry. Also they are drip dry, no rinse sanitizers and you can run these products through your hot water heater also. you can add these products to a 1/3 tank of fresh water,, drive down the road a bit to splash around the tank,, run through faucets and dump the tank. Refill, run a shot of water through your waterline and your done. Go to Amazon and check them out.

Not sure about your RV, but the fresh water tank on our Imagine 2600RB DOES have an overfill drain. It is the source of many complaints regarding loss of water in route to dry camp sites. Can’t see any reason why your RV would be any different.

With respect to sanatizing your system, you should follow the instructions in your owners manual regarding sanitizing your system. Be wary of suggestions that are contrary to that guidance.
