CoolSigns Posted July 7, 2011 Report Share Posted July 7, 2011 Is the garbage disposal drain piping proper? Click to Enlarge 49.98 KB Link to comment Share on other sites More sharing options...
Garet Posted July 7, 2011 Report Share Posted July 7, 2011 No. It should be smooth-walled. I call those 'cheater' fittings. They tend to collect solids and they tend to crack on the ribs. BTW, neither the dishwasher drain nor the NM cable to the disposal are right either. Link to comment Share on other sites More sharing options...
Charlie R Posted July 7, 2011 Report Share Posted July 7, 2011 Nope. Those radiator hose pieces are intended as temporary repair parts only, not for permanent installation. Go to the store and pick one up, you can't find a UPC marking on them anywhere. And yes, there are other problems as Garet pointed out. Link to comment Share on other sites More sharing options...

Tom Raymond Posted July 8, 2011 Report Share Posted July 8, 2011 That whole thing screams "the dude at Home Depot showed me how to install it." Hee, hee! I actually did laugh out loud when I read that. Take another look at your pic, there's plenty of evidence that the whole mess has been leaking for a while too.

John Dirks Jr Posted July 9, 2011 Report Share Posted July 9, 2011 Man, with all the solids comming through a disposal, there couldn't be a worse place for a flex drain pipe. This cut from IRC states that drain piping shall be smooth walled interior. That makes those flex fittings non compliant in most areas. P3002.3.1 Drainage. Drainage fittings shall have a smooth interior waterway of the same diameter as the piping served. All fittings shall conform to the type of pipe used. Drainage fittings shall have no ledges, shoulders or reductions which can retard or obstruct drainage flow in the piping. Threaded drainage pipe fittings shall be of the recessed drainage type, black or galvanized. Drainage fittings shall be designed to maintain one-fourth unit vertical in 12 units horizontal (2-percent slope) grade. Link to comment Share on other sites More sharing options...

msteger Posted July 31, 2011 Report Share Posted July 31, 2011 It looks like the dishwasher drain line also lacks a high loop or air gap. Link to comment Share on other sites More sharing options...

Neal Lewis Posted August 26, 2011 Report Share Posted August 26, 2011 Looks to me like that's the drain hose that comes in the box with the dishwasher. Link to comment Share on other sites More sharing options...
