DW drain ?

[Denray]

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?

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]

Thanks Erby. Just looked funky. Not a big deal for the vent ending there?

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.

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.

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?

Kinda hard imagining that puppy is going to siphon anything.

The vent, otoh, is pretty stupid. Nothing but wrong.

[Denray]

Thank you for the replies, all.

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.

Not all modern dishwashers have factory installed high loops. I just installed an 18" Frigidaire that didn't.
