I realise that this question could equally well be posted in the Water Softener sub-forum, but since the issue is related to the plumbing, rather than the softener itself, I thought it might get more eyes in this one.
For reference, my original thread regarding softener sizing can be found here:
Now that I've (almost) decided on a softener, it's time to start thinking about the location of the plumbing required for installation. I'm going to be putting the softener in the corner of the garage, since that is where the main water line enters the home. The photos here show the location I'm thinking of, and also the water piping for the automatic sprinkler system, and it's flow detector.
Garage corner location:
Thankfully the sprinkler system is separated from the rest of the house outside, so I don't need to worry about flow rate for the sprinklers:
The property has no stub outs for a softener, and all of the pipe work into the home is boxed in just inside the garage door. There is going to be quite a bit of work cutting the drywall and coupling in the softener, but I'm not too concerned about that.
My bigger concern is the drain line, because there is no existing standpipe, or drain in the garage at all. The photo below is taken of the side wall of the garage, and does show a drain coming down the side of the wall; I believe this is from the kitchen above.
Close Up:
At first, it would seem most appropriate to tap a small P-trap into this drain, and make repairs to the drywall afterwards, but I'm concerned about venting. This drain is obviously vented already, but I'm now lower than the vent, and there are no additional vents anywhere nearby.
The other alternative is in the crawl space at the back of the garage, where there are two drain stacks available, one has a cap that could be removed (This one is further away, and would be much more complicated and expensive to work with):
And the other has a clean out/cap that could be utilised:
My question then, is this: What would be the best approach to connect the drain line, keeping in consideration that there probably ought to be an air gap, and almost certainly needs to be a P-trap of some sort.
My primary interest is keeping everything safe, dry and clean, but I'd like to stay to code as well if at all possible. My house is located in the Northern Californian city of Sunnyvale if that helps at all.
