Washer and laundry tub drain design

[Ericksimo]

Plumbing in a drain for a washer and laundry tub. Standpipe will terminate at 36", vents will connect at 42" or higher. Does this look like a good design?

The vent takeoff on the standpipe trap is backwards, and WA (UPC) requires a combo, not a san-tee on its back.

Is the 90 below the san-tee on the right a long turn? (Not familiar enough with the fittings to tell from a picture). It needs to be.

Otherwise the portion shown looks good.

Cheers, Wayne

https://terrylove.com/forums/index.php?threads/basement-laundry-drain-layout.83257/ says that the middle of the trap arm must be no higher than 18 inches from the floor. I don't see the reason for that, but that does not matter.

From vertical to horizontal needs to be a long turn, it's a medium in the picture.

Thanks for the replies! I swapped out the San tee on it's back for a combo (and turned it around).

The trap arm is 16" above the floor, so I just cleaned the 18" max.

I guess it's another trip to the supply house to see if I can find a long turn street elbow. Using a hub x hub puts me a bit high for the washer tub drain.

Did you mean for the laundry sink drain on the right? You can also use a street 45, san-tee with barrel on a 45, and another street 45, if you prefer. But a san-tee and a street LT90 (or street san-tee and a LT90) would be more typical.

Something like this?

 

[Terry]

Yes, that works, no need for the trip now.

 

[Ericksimo]

Excellent! I certainly appreciate all the advice on this.
