Stupid question time /sanitizing black water tank

to dump at home there are a few options. one is to install a dump station with water at home and another is what I did, I bought a sewer solution and cut my clean out for the house off and installed a "T" with a 1 1/4" opening for the hose for the sewer solution. just use a plain garden house and flush out the tank and it goes right down the house sewer.
