Supply line won't stop running. Main water supply off
I was doing some bathroom remodeling and attempted to remove an old supply valve. It would not budge so I decided to cut the copper tubing underneath it and put on a new shutoff valve with a compression fitting.
The problem is that water just kept coming out of that supply line. The main water was turned off. I was able to get the fitting on, but it is not quite right and needs to be redone (slight leak, can't not tighten it anymore). I've got the line dumping into a 5 gallon bucket. I would say there is enough water coming out to fill it up in 2-3 hours.
Does anyone have any ideas on why water will not stop coming out. It seems to be the only one in the house that way. There is plenty of copper left to cut to try another compression valve, but I don't really want to try that with the water spraying out again.
Thanks,
Paul
