Renovating the [COLOR=blue ! important][COLOR=blue ! important]basement[/COLOR][/COLOR] - Canada
Opened up a wall and the washer, RO waste water line and the line from the water softener all go into the top of an an open 1 1/2 " drain hose.
4" down the drain hose a sink with ptrap
Then the line goes under the [COLOR=blue ! important][COLOR=blue ! important]concrete[/COLOR][/COLOR] and ends up coming out inside a floor drain.
This drain hose isn't vented and I am wondering if it needs to be and if I need to ptrap the washer/RO/softener lines?
Here is a picture...
