Had a service call on a clogged kitchen sink. Double bowl with disposer on the right and dishwasher drain connected on the extension down tube on the left side. She had a water filtration system with a little spout to the right of the faucet, and a three-gang cartridge array screwed to the left side of the sink cabinet. There's a pressure tank under there also, but I don't know what for. Ain't my gig. Always eager to learn, but...................
The lady demonstrated the fact that when she ran the disposer, water squirted out the side of the little filtered water spout, the sink being clogged.
Looking under the sink, there's a drain line coming down from the little-bitty filtered water spout and draining into the tubular sink drain via a saddle valve with a push-type fitting for said drainline.
So, when the sink is clogged up, running the disposer forces nasty water up through the drainline for the filtered water spout and out the venthole on the spout.
Don't know what the drain line is for exactly. Maybe to draw off unused filtered water?
I used the Reach 4 method to unclog the sink. Unscrewed the Studer vent and ran a cup of Dawn down the pipe. Replaced the studervent and ran hot water down the drain. I ran water into a pail in the sink until it got really hot, then directed the flow into the sink so that the beneficial effect of the hot water would materialize sooner. Did that three times. Third time the sinks started draining, and I ran the hot water for an additional ten minutes wide open.
Customer contacted the water filter people while all this was going on. She suggested that I move the d/w drain over to the disposer and reattach the filtered water spout drain on to the left drain since the nasty water from the d/w might tend to clog the filtered drain as it was set up.
No shirt, shylock.
Calls for an air gap in my opinion.
Every day's a new adventure.
