Denray Posted March 4, 2015 Report Share Posted March 4, 2015 DW is in center island by itself. Drain line not sloped to drain. Vent exits into crawl space. No air gap viewed. This can't be good?

Erby Posted March 4, 2015 Report Share Posted March 4, 2015 If it's a modern dishwasher with a built in high loop, I don't see a problem with it. Discharges to the drain through a trap so sewer gases won't be coming into the house. I'd like to see a more consistent slope but it IS a pumped line, not a gravity drain. What is YOUR issue with it?

Denray Posted March 4, 2015 Author Report Share Posted March 4, 2015 Thanks Erby. Just looked funky. Not a big deal for the vent ending there? Quote Link to comment Share on other sites More sharing options...
Bill Kibbel Posted March 5, 2015 Report Share Posted March 5, 2015 Doesn't CA use the UPC? I seem to remember something about CA requiring dishwasher discharge has to be installed with an airgap fitting above the flood level of the sink.

patt Posted March 5, 2015 Report Share Posted March 5, 2015 Good memory Bill, I don't think CA has ever allowed the high loop installation. CPC 2013 807.4 Domestic Dishwashing Machine. No domestic dish- washing machine shall be directly connected to a drainage system or food waste disposer without the use of an approved dishwasher air gap on the discharge side of the dishwashing machine. Listed air gaps shall be installed with the flood-level (FL) marking at or above the flood level of the sink or drainboard, whichever is higher.

inspector57 Posted March 5, 2015 Report Share Posted March 5, 2015 Yes it is a big deal for the vent to the crawl space interior. I think the high loop is only allowed if connecting to the sink/dishwasher tail piece, no? Quote Link to comment Share on other sites More sharing options...
kurt Posted March 5, 2015 Report Share Posted March 5, 2015 Kinda hard imagining that puppy is going to siphon anything. The vent, otoh, is pretty stupid. Nothing but wrong. Quote Link to comment Share on other sites More sharing options...

Erby Posted March 5, 2015 Report Share Posted March 5, 2015 Didn't look at the vent pipe. A glance at it made me think it was a pipe going up into the house. Now I see it ends there. That would be an issue of escaping sewer gas. Quote Link to comment Share on other sites More sharing options...
Tom Raymond Posted March 5, 2015 Report Share Posted March 5, 2015 Not all modern dishwashers have factory installed high loops. I just installed an 18" Frigidaire that didn't. Quote Link to comment Share on other sites More sharing options...
