Full hookup?

[badkat]

OK, we have full hookups but we wait til we have tanks that are 3/4 full to hook up..does it matter? We are moving soon to being stopped for 3 months. When do you hook up? If you are living everyday with showering that has gotta work.

I would hook up, but keep the valves shut until ready to dump, then close them again after dumping. That ensures that there is enough flow to move the nasty stuff out of the tank and on its way.

It doesn't really matter when you hookup. Many people hookup right away and leave the gray tank valve open and wait till the black tank gets to at least 3/4 to dump the black, some closing the gray 1 day before dumping the black.

NOTE; It is important to make sure the gray is closed before dumping the black.

Keep your black tank valve closed until the tank fills up then dump. Gray water should be left open until one or two days before you dump the black tank then close the gray valve you will naturally accumulate gray water. This gray water is used to flush the black tank residue out of the sewer hose.

I generally rinse the black tank unless I am hitting the road where I let the natural sloshing take place . I always flush at least three toilet bowls of water down into the tank after dumping for a primer more water is better than less....

An old timer suggested I put about 5 gallons of water and chemical in both the gray and black tanks after every emptying as gray water residue needs treatment as well. The movement towing to the next stop helps clean the tanks by splashing the side walls and tops of the tanks before the next filling loads are deposited.
