Leak from tub drain... possibly trap?
My wife was getting a shower today. I was in the kitchen and I noticed a leak in the ceiling. To describe the leak its as if someone poured a cup of water, stopped, poured it again, stopped and that was it. I yelled up to my wife and she turned the water off. I checed out the drain at the front of the tub and the water supply lines. They are all OK. In the kitchen the leak seems to be near the middle of the tub. (talking to my neighbors, they have told me that there is a trap in the ceiling in the tub drain). Is that type of leak the characteristic of a trap or drum trap? I tub and sink in the bathroom drain fine, and aren't slow. I took a shower today today, and there were no leaks at all. Any thoughts? BTW my house is a dutch colonial and was built in 1925. The bathroom was redone at one point, and the drains for the tub and sink are copper pipe. Could they have just tapped into the lead pipe that was originally there, or the original trap?
Thanks,
Kevin
