Bathtub Flow Doesn't Stop even with both knobs in off position
We have a bathtub in our upstairs bathroom. The faucet has always leaked a little so we tried to fix it this week. We bought new stems and put them on. (I think that's what they're called... there's one for hot and one for cold, they go straight into the pipes and then the handles go onto them). While replacing the knobs, we turned off the water supply to the house. Upon replacing the stems and turning the water supply back on, the bath faucet runs immediately like someone is taking a bath. Even when the hot and cold knobs are in the completely OFF position. I think the problem is with the cold knob as that was the leaky one before and the water coming out of the faucet is cold.
For now, we put a plug in place of the cold stem so that we can have the water on for the rest of this house. But we really really really need to get this problem fixed immediately. Any ideas?
Thank you in advance!
There are only two knobs and no shower head. Just a plain old bathtub.
