I'm replacing the laundry tub & taps down in the basement and I'm kinda stumped by the old set-up.
It's a standard 2 handle tap but there's a 1/4" plastic tube that comes out of the bottom of the tap, goes about 3' along the wall and then goes inside the wall. There's a bathroom on the other side of the wall and that's where the vanity and bathroom sink is but I can't see where the tube ends up under the cabinet.
I'm on a septic system and any water from downstairs goes into the sewage sump, which is in the laundry room, and is then pumped out to the septic.
If I turn the tap on very slowly, water flows down this tube into the sump before any water comes out of the tap.
I originally thought the tube may go thru the wall into the vanity drain, but it would have been much easier to just connect it to the laundry tub drain right beside it.
Sorry for the long post but it's kinda weird to explain and I'm totally stumped on this, but I imagine I can just do away with the tube and hook up the new tub and taps in the normal way.
Here's a pic from under the tub showing the plastic tube coming out of the bottom of the tap between the 2 water supply lines.
The house is only 10 years old so it's not some weirdo antique set-up.
Any thoughts ??
