Adding water after dumping black tank

Don't understand the use of buckets? And not all RV's have those back flush options.

BUT....Most if not all RV's have a sink that dumps into the black tank.
Find out if your bathroom sink dumps into the black tank.

Dump black tank
and BEFORE you unhook from shore station, run the faucet in the sink to put a couple of gallons into the black and add your chems. Really doesn't get any easier than that! :W

Actually when I am hooked up at a CG I dump the black, close the valve and fill the black tank up to full with water from the sink while I am packing up and then dump again to flush out the tank. Close the valve and then run the sink to add that small amount for the chems.
