Draining laundry sink into washer stack?


On top of everything else a mechanical discharge (anything with a pump) must be piped below a gravity discharge.

Draining laundry sink into washer stack?


they only put duct tape over the top because either water or soap suds would come out when washer is discharging....need to change entire set up to accept new tray and install vent making sure not to double trap system...ben

I would remove the existing below the floor trap, reuse the drain to plumb the sink with a trap and add an AAV for the sink. Now drain the washer into the sink.

4) There is no need for a "secondary vent". In fact, such an application is precluded by code. A vent should either go to atmosphere outside the house, or be protected by an AAV

What you have now is a complete mess, and should be cleaned up

Don’t you just love the way some DIY’ers Butcher the code even though they are being told how to do it correct way, if you r asking for help, do it the correct way, there is a reason why a plumbing code was put together just because you pipe something in and it works doesn’t mean it won’t have some adverse effect in some fashion down the road, . There are some things the DIY’ers should stay away from.
