water softener install

I plan on installing a water softener soon. I'm looking at the Whirlpool 44,000 WHES 44. I just had a quick question regarding the pipes.

I've attached 2 photos showing the pipe situation in my garage. It is a 2008 home. The U-pipe into which to splice the input and output from the softener is obvious. But what are the 2 connections/lines below it? Can one of these be used as a drain line for the softener? I'm assuming so, considering it is so conveniently located to the U-pipe as well as the proper electrical outlets. But I just wanted to make sure. For what it's worth, if you physically move one of the two bottom connections, the other moves with it, so they are obviously connected.

The bottom pipe with the square cap is the sewer clean out. Leave this one alone. The top pipe is a 1 1/2" drain pipe. U need to attach a pee trap to this with an air gap. The air gap is simply a 1 1/2" pipe with the drain hose attached to it. A section of the pipe will be cut away so if the drain backs up it does not come in contact with the drain hose.

One final question. My home has an irrigation system that was installed when the home was built - not as an add-on. With my softener I want to bypass the irrigation system and ONLY supply softened water to the house. If I tap into the pre-installed soft water loop, this SHOULD bypass the irrigation system, correct? In other words, the split off for the irrigation system should have already occurred BEFORE this soft water loop?

Is there any reason whatsoever to expect otherwise? Any easy way to absolutely tell?

Trust, but verify! When you cut the loop, push a sharkbite cap on both stubs, turn on the water, and see if you have pressure at the irrigation feed. If you do, then it's before the loop. If you don't, it's not.

I always install a shut off valve before the softener. You can turn off the valve and run the sprinkler system. Chances of the sprinkler system being before the softener is 99.99999999999%.
