I cleaned a pair of boots off in the tub. Debris went down the drain from off the boots and I think that this may be part of the problem I am experiencing. Every time I take a bath or shower and the water goes down the drain, it comes out in the basement from under the stairs. This happened twice. Is this a clogged drain problem or a broken or leaking pipe?please help.:(

Sounds like you have a blockage downstream from the basement floor drain the water came up out of.
The answer is to take the strainer off the floor drain and send a snake past the trap and about 15feet out in the drainline. To test shove a garden hose down the floor drain and turn on the water. If it doesn't back up you have removed the clog. Good luck, Tom
