It is clean potable water It is not considered grey water which is not allowed.

There is no prohibition for doing so, except it is not to go into any storm-water drain system.

As another poster stated pools overflow onto the ground

I read JRcorvette's question 2 different ways.

1. Based on the flow of water, do the filters come first?

2. Do customers have the filters or softener installed first and later add the other?

Thank you. The plumbing code is very confusing on this issue. But, since most Village garages do not have a floor drain, the only other sewer drain you could use is the laundry tub, which is usually on the other side of the garage from where you need to locate the water softener, or to tap into the washing machine drain. The only other option would be to dig up the sewer drain in the front yard. So, it is logical to drain the water onto the ground. Note that Sumter County does not require a building permit to install a water softener.

Filter location
 

Directions with my softener said after directions with filter said before. I researched and found more info that said putting filter before the softener will extend the life of the media in the softener. So that's the way I did mine, filter before softener. Works great.

Also, if there is salt in the mixture, it will kill any grass it comes in contact with. Please be careful.

FYI, the media (resin) lasts 3 to 5 years max, it must be replaced.

Best way to tell that it needs replacing?

When it’s not softening anymore.

Decided against the water softener because of this issue. I had one previously but, because it was located in the basement, it drained into the waste water. Not possible here. So polluting less. Anyway, this water is not so hard, I can live with it.
