Washing machine discharge

[Neal Lewis]

Brand new construction. The washing machine drain hose discharges into a laundry sink. Not sure it there's a drain line in the wall.

I'm assuming this is unsanitary and a code violation since the sink drain is not sized for a washer. Tell me I'm correct.

[John Dirks Jr]

From 2006 IRC - The last sentence says its ok I think.

P2706.3 Prohibited waste receptors.

Plumbing fixtures that are used for domestic or culinary purposes shall not be used to receive the discharge of indirect waste piping.

Exceptions:

1. A kitchen sink trap is acceptable for use as a receptor for a dishwasher.

2. A laundry tray is acceptable for use as a receptor for a clothes washing machine.

In NJ, a laundry sink is an acceptable receptor for AC condensate, clothes washer, water treatment backwash and water heater relief discharge.

I might not be a violation, but it's pretty damn cheezy in a newly constructed house. If the guy couldn't be bothered to install a stand pipe, what else did he skimp on?
