Stupid Question, May Be. Pipe Coming Out Of Cold Water Supply And Dripping.


ok. I've been at the estimate for basement remodeling today and saw something I have not seen before or may be did not pay attention to it. I'm not plumber more like gc/carpenter. there was an utility sink with hot/cold water coming into the faucet. Only thing confused me is: about two feet of the faucet(pipes goes up) there is a tee and some kind of valve installed on cold water pipe and another pipe coming of that "valve" (there is no control or screw or handle on that valve). Water is continuesly dripping from that pipe into utility sink (it was dripping while I was there and it was obvious by the spot left on the sink that it was dripping since the house was built may be.

Just curious what is that and what is that for.

Will appreciate opinions.

Maybe the don't use the sink very much or they are gone for periods of time and this keeps the trap wet to prevent sewer gas from coming up into the sink. This is done all the time in commercial bathrooms, with every flush a bit of water goes to the floor drains to keep them wet. You don't see it as it is installed during the rough in stage. But its there.

Guys, I'm sorry, no pictures unfortunately. Its customers house and im not planning to do any work on the utility sink so that would look weird if I would start taking pictures of it))

Looked at the automatic freeze preventer valves. The one that was there looks much more simple. More like a thick brass elbow. (all piping is cpvc). So I'm not sure if it's what it is.
