 Plumbing a special water softener loop
Author: holdemfoldem (NV)

The only access to water at my house is in from the city, through my inside garage wall and back out/through same wall and on to everywhere. On the opposite side of the wall, (outside garage wall), there are some pipes, one of which has a backflow preventer to keep sprinkler water from backwashing into house water. There is also another pipe coming out of the wall and into the ground. Not sure what this is for but I'm guessing it might hook up under ground to the pipes with the backflow preventer.

Done lots of research and I want softened water for the whole house, including what we will drink, just not for my sprinklers.

I'm thinking I need to cut a hole in the inside garage wall and see if I can determine which pipe(s) lead(s) outside and which go, (hopefully), into the house.

I'd post pictures if I knew how but all I can find requires a url, and I want to attach from my local hard drive.

The back flow preventer has a direction of flow. Check to see what way the flow is going and tie in your softener after the tee for the lawn sprinklers.

Thanks! Oriented from the direction of flow, Would this tee be after the backflow preventer, or before. Thanks again.

We really cannot tell you how to do it. You have to cut the line somewhere, pipe through the water softener, and then BACK to where you cut the pipe. The sprinkler backflow preventer/vacuum breaker has to be connected to the pipe going TO the water softener.
