I just did. He needs an air break not an air gap. The plumber that installed the drain knew the code and knew what he was doing too. Imagine that. Lots of folks that aren't plumbers and dont understand the code get confused by the difference.
AIR BREAK (Drainage System). A piping arrangement in
which a drain from a fixture, appliance or device discharges indirectly
into another fixture, receptacle or interceptor at a point
below the flood level rim.
+An air break is an indirect drainage method where
waste discharges to the drainage system through piping
that terminates below the flood level rim of an approved
receptor. An air break is commonly used to protect mechanical
equipment from sewage backup in the event
that stoppage occurs. It also protects the drainage system
from adverse pressure conditions caused by
pumped discharge [see Figure 202(4)].
Softener discharge is considered "pumped discharge"
AIR GAP (Drainage System). The unobstructed vertical distance
through the free atmosphere between the outlet of the
waste pipe and the flood level rim of the receptacle into which
the waste pipe is discharging.
+An air gap (drainage system) is a type of indirect waste
where waste is discharged to the drainage system
through piping that terminates at a specified distance
above the flood level rim of an approved receptor.
An air gap is commonly installed on drain lines serving
equipment that is used in the preparation, storage
and service of food, the conveyance of potable water,
and the sterilization of medical equipment. The air gap
serves as an impossible barrier for sewage to overcome
in the event that stoppage occurs in the receptor drain,
because sewage backup would overflow the receptor
drain flood level before it came in contact with the drain
line above [see Figure 202(4)].
IIRC weren't you the guy that spent three or four pages of a thread railing on about how you don't think that there should be any regulation requiring either an air break or an air gap? LOL
Hey you....quit reading my posts LOL
OK, good that's settled. No drain issues to deal with. I do have a small leak when doing a backwash. I coated the o-ring with some light Teflon grease on the 90 degree elbow at the valve. That helped but it's still a small dribble which seems to be coming out of the gray clip and not from the top. That, and just a comment on the valve itself. Or, perhaps rather the directions but for someone not that familiar with water softeners (but learning every day!) it wasn't clear how to change the regeneration cycle to fit my house/family needs.
The default was 4600+ gallons which is of course overly-conservative for a family of 4 with a 100gal/day useage and hardness of 10. I now have it set to do a regeneration every 3360 gal or every 12 days, whichever comes first. But to do that, you have to manipulate the regeneration cycle time steps which isn't really explained. The customer support from Ohiopurewaterco was very helpful. I probably could have figured it out but it would have taken a bit of trial and error.
I am not a plumber but I am a certified installer. The way I was taught and my understanding seem to agree with the air gap, not air break code. The code is written in a way that can make it very difficult to interpret but I see a major difference between the gap/break writings. Please understand, and I am not arguing or trying to one-up anyone here unlike the antagonizer on this site, I am simply trying to grow my knowledge and understanding of the legal codes better.
An air-break references interconnections between two appliances or receptor that falls below the "flood level rim"
An air gap is a unobstructed vertical distance through the atmosphere of waste discharge from a potable water, food prep, medical... system.
A water softener falls under the potable water category, and even though the water is pressurized to the drain, the other function of an air break is for the absolute separation of potable / sewer connections in the event of a loss of pressure, or a vacuum on the potable supply system. If a cities power goes down, sewage may not be pumped and sewer backup can occur, City water pressure may also be lost, so a vacuum can easily form in the potable plumbing system. If the softener were in regeneration at that time, the possibility of sewage being siphoned is a definite possibility. A recent lawsuit of over 5 million dollars in orange county is currently being pursued due to this and the result was a child getting Hep C. The softener tested positive for Hep C, and the lack of a proper air-gap is the main part of this case.
In my opinion, better safe than sorry.
I don't want to turn this into a who's right / who's wrong topic, I just want to add my thoughts and get some clarification. Also, I would never even consider installing a softener or RO system without a proper air gap. They cost less than $20.
Lets here more, but without the normal personal attacks by a certain person who just cant help themselves. :)
An air gap is always the preferred and most reliable protection against cross contamination, but for whatever reason the code will allow an air break. In truth though and with the installation here, it wouldn't have been anymore difficult to to pipe it as an air gap. Anyway, what he has there is just fine.
