ramdino Posted November 6, 2012 Report Share Posted November 6, 2012 This is a weird way to vent a kitchen sink. Anyone seen this before? The waste is on the right with no vent above the waste. where you would normally see a vent or a studor vent. The pipe runs across the back of the cabinet and down into the crawl where it ties into the waste again. What the heck?

Jim Katen Posted November 6, 2012 Report Share Posted November 6, 2012 Looks like someone trying to make an island vent. They're not very clear on the concept. Here's a description of what they were trying to do, from the UPC: Traps for island sinks and similar equipment shall be roughed in above the floor and may be vented by extending the vent as high. as possible, but not less than the drainboard height and then returning it downward and connecting it to the horizontal sink drain immediately downstream from the vertical fixture drain. The return vent shall be connected to the horizontal drain through a wye-branch fitting and shall, in addition, be provided with a foot vent taken off the vertical fixture vent by means of a wye branch immediately below the floor and extending to the nearest partition and then through the roof to the open air, or may be connected to other vents at a point not less than six (6) inches (152 mrn) above the floodlevel rim of the fixtures served. Drainage fittings shall be used on all parts of the vent below the floor level, and a minimum slope of one-quarter (1/4) inch per foot (20.9 mm/m) back to the drain shall be maintained, The return bend used under the drainboard shall be a one (1) piece fitting or an assembly of a forty-five (45) degree (0.79 rad), a ninety (90) degree (1.6 rad), and a forty-five (45) degree (0.79 rad) elbow in the order named. Pipe sizing shall be as elsewhere required in this code. The island sink drain, upstream of the returned vent, shall serve no other fixtures. An accessible cleanout shall be installed in the vertical portion of the foot vent. Quote Link to comment Share on other sites More sharing options...
ramdino Posted November 6, 2012 Author Report Share Posted November 6, 2012 Ok' never seen that but they sure didn't follow the code, not that I do a " code" inspection. They piped it upstream before the waste, and the waste ran uphill. Plus they used some weird cloth with epoxy for the joints Click to Enlarge 12.46 KB Click to Enlarge 14.96 KB Quote Link to comment Share on other sites More sharing options...
Scottpat Posted November 6, 2012 Report Share Posted November 6, 2012 A simple AAV would solve the problem..... Quote Link to comment Share on other sites More sharing options...
ramdino Posted November 6, 2012 Author Report Share Posted November 6, 2012 Yep'Don't know why they did not got to a studor vent rather than all use all that plastic. Maybe the code guy gigged 'em. Quote Link to comment Share on other sites More sharing options...
