I really have no idea what they were trying to accomplish here. A vent?:mrgreen:
Not a vent.
Obviously. I don’t know why someone would tape a green funnel onto a drain saddle though.
People do strange things. While this might not work well as a drain it does have great entertainment value. It made both of us smile.
More freaked out by Casper the Ghost on the wall just left of the trap.
Around here I call out plastic 1/4 inch waterlines to fridges.
That was probably the drain connection for a RO under sink filter, and they needed something to plug the hole once removed. Grabbed the nearest thing in the junk drawer.
It looks like a abandonded drain connection for a RO system
Ya trigger finger is faster than mine:p
Because plastic waterlines are not allowed here.
Pex is not allowed either as it is plastic as well.
I suggest they switch to copper.
I was going to say drain for a reverse osmosis system…
For easy ear wax removal , no mess goes right down the drain…
