We seem to have a problem with out tub drain. It seems if we shower one right after another the tub drain leaks. and of course we didn't know about it until it leaked through to the lower level. where could this leak be and/or what may be causing it. I've heard that it could be clogged up pipes. we don't have a hair trap just the lever stopper. I've checked the shower access and that appears dry. So I guess I'm asking what should I be looking for and what if any thing can I do by myself before I call in the plumber?

 

The most common tub drain leak occurs when the old plumber's putty under the drain lip gets too old and loses its seal.
To replace it, unscrew the tub drain counter-clockwise. There is a tub drain tool that works on the four crosspieces. If you can't borrow or buy one, you can use the handles of a pair of channel-lock pliers stuck down in the drain and a screwdriver in the teeth for leverage to unscrew it. Be careful when using this method, as it only puts pressure against two of the cross pieces, and you don't want to break them if you can help it.
Heat the old drain putty with a hair dryer to soften it before attempting to unscrew it.
Clean the old putty off.
Roll a roll of new plumber's putty in your hands about the size of a pencil, wrap it around the drain hole depression, and tighten the drain lip back down on it.
Wipe away the excess putty.
Should solve the problem.
Good Luck!
