I'm in CA and I presume the softener drain discharge must go to the sewer - if not, let me know!
My best drain option is to a nearby laundry sink. The hose that came with the softener is clear plastic flex with a 3/8" ID. Instead, I plan to run 1/2" pex up to a height of about 8' 6" to 9 feet and then down and underneath the sink. Under the sink, I'll connect to a dishwasher air gap that will in turn connect to a dishwasher tailpipe (that drains the sink, no dishwasher).
My questions:
1. Code says the softener drain should maintain a 1" air gap above the drain...technically speaking in using a dishwasher air gap, the drain is below the air gap. Is this still acceptable practice?
2. Total drain pipe distance is about 25 feet and about 8.5 - 9 feet in overall height. Not sure who came up with the 8 foot number that these drains could rise because that barely gets you up into the ceiling joists, if at all. Will the softener drain still work properly if the overall height is 9 feet?
3. Will the 1/16" larger ID of the PEX pipe (vs the clear plastic tubing) reduce the height and/or distance the softener can drain properly?
4. If the above won't work, I also have a laundry stand pipe near the sink. Can the softener drain attach to the stand pipe along with the washing machine hose? Not sure if that will work as the water supply valves and stand pipe are in a washer valve box.
thanks in advance.
