I live in a house. In the basement there is a wash basin and near the knobs to turn on and off the water there is thin plastic tube coming from the water pipe and when we use the wash basin some water also comes into the wash basin through that tube. What is the purpose of this plastic tube? thanks
If I am understanding you correctly - The tube is used for hooking up the washing machine to drain it on the spin and drain cycles. Hope this has been a help.
Might have been a water line to a refrigerator ice maker that was cut when the previous owner moved. There should be some way to shut off this line where it attaches to the main water line.
You apparently have not live usd in this house for too long a time, at least not long enough to have seen this wash basin installed. I would surmise that the tube was most likely used to fill some container that had a fairly small neck opening, like a water bottle. It does seem odd that the tube and the fixture would both be active at the same time without a shut off on the tube. ?? Strange things, but I'm sure whoever had it put there had a good reason.
