Tom Raymond 27 Posted March 6, 2015 Report Share Posted March 6, 2015 It's got a trap and a high loop. It's wrong but will work just fine. I'd call it out, so the next guy doesn't call me a putz. Quote Link to post Share on other sites
kurt 2 Posted March 6, 2015 Author Report Share Posted March 6, 2015 That's what I thought. What's wrong with it, though? I couldn't come up with anything specific. Quote Link to post Share on other sites
Erby 39 Posted March 6, 2015 Report Share Posted March 6, 2015 Nothing. It's just unusual. Quote Link to post Share on other sites
kurt 2 Posted March 6, 2015 Author Report Share Posted March 6, 2015 So, no one has a good reason why this is wrong? Anyone? Bueller? Quote Link to post Share on other sites
John Kogel 33 Posted March 6, 2015 Report Share Posted March 6, 2015 The DW floods the sink trap and being elevated a bit it pushes water up the sink drain. Maybe. It looks good to me. I would call it unconventional and move on. Quote Link to post Share on other sites
Jim Katen 122 Posted March 6, 2015 Report Share Posted March 6, 2015 The sanitary tee on its back is wrong. Quote Link to post Share on other sites
Jim Baird 27 Posted March 6, 2015 Report Share Posted March 6, 2015 The tee, and hard to judge elevation but it does look like the DW discharge might well flood the sink basket too. Quote Link to post Share on other sites
patt 0 Posted March 6, 2015 Report Share Posted March 6, 2015 UPC only allows one trap per trap arm. Quote Link to post Share on other sites
Tom Raymond 27 Posted March 6, 2015 Report Share Posted March 6, 2015 There are 2 fittings designed to connect the dishwasher drain to the trap, neither of which appear in that get up. Quote Link to post Share on other sites
kurt 2 Posted March 6, 2015 Author Report Share Posted March 6, 2015 I thought about the trap arm thing. Didn't think about the tee on its back. How bad is bad here? Both seem relatively benign. Quote Link to post Share on other sites
kurt 2 Posted March 6, 2015 Author Report Share Posted March 6, 2015 There are 2 fittings designed to connect the dishwasher drain to the trap, neither of which appear in that get up. Yeah, but does that really matter? Quote Link to post Share on other sites
Tom Raymond 27 Posted March 6, 2015 Report Share Posted March 6, 2015 If the dishwasher goes unused for an extended period its trap could go dry. It won't smell very good when the door gets opened. A la Katen, unconventional things tend to behave unconventionally. Quote Link to post Share on other sites
kurt 2 Posted March 7, 2015 Author Report Share Posted March 7, 2015 It's in a building I bought. It works fine. When I saw it, I was actually kind of impressed. One thing for certain....I'm not changing it. It's the "old building high sink drain exit" thing; can't fix it without opening up the entire wall and rebuilding the DWV system.
