Saltwater Tank and Septic System

[The Codfather]

Steve,
the problem that you might encounter if that you have a lot of bacteria in the septic system. when you flush a large volume of water, be it fresh or salty, it could potentially affect the amount of bacteria in the system. We recommend that even regeneration from water softeners be discharged elsewhere and not through the septic system. Now if there is a small amount, in other words a small tank, with small wc's it may be fine, but i do not know the size of your septic system nor the size of your tank.
