Thanks for the replies so far. There is no leaks in the shower valves.
When the tub is used for showering there is abaolutely no leaks whatsover anywhere. I even tried turning on the shower, pulling off the shower head (its on a flexible hose) and aiming it directly at the tiled wall and even directly into the drain and no leaks at all. Bone dry.
The only time the tub drain leaks is when somebody takes a hot bath.
I have tried to recreated it by filling the tub several times and letting it sit and then draining it and I can't get even a single drop of water to leak.
I even had somebody standing and walking around in the tub while it was full. It didn't leak a drop.
Also.. its positively leaking out of the tub drain because I put a baking pan underneath it and the pan had an inch of water in it after my daughter took a bath. Nothing else was wet.
My tub has a large access door to get to all the plumbing so everything is very easily accessable.
In case anybody asks.. my tub does not have a overflow drain and the spout where the water enters the tub is not leaking at all. The leak is coming from the drain under the tub and it only leaks when somebody takes a hot bath. If I had to guess.. I would say my tub is at least 40 years old. Its in great shape but its old. All the pipes that connecto to it are copper or standard steel threaded water pipes. It would be very easy to replace the entire shoe, threaded drain in the tub and the horizontal drain pipe connected to the vertical drain pipe but I don't want to make matters worse. I just can't figure out why it leaks only when a hot bath is being used.
At first I thought it was this..
The plumbers putty wore out and when somebody took a hot bath the hot water would soften up the already worn out putty and cause a leak because the rubber gasket under the tub was shot too.
So, I cleaned everything up nice, installed a new gasket and new plumbers putty. Bone dry for showers and after I filled the tub with cold water and let it sit for an hour.
Then.. somebody took a hot bath. I ran upstairs afterwards and the pan I put under the drain shoe had at least 16 ounces of water in it.
I unscrewed the drain and got out the plumbers putty and molded it around the drain opening in the tub (its a beveled hole down to the shoe) and I added a bunch more to the bezel around the drain cover itself and screwed it in. I whole bunch of putty squeezed out around the drain when I tightened it down. That was after midnight last night. I took a shower this morning and of course the pan was bone dry. When I get home tonight I will check after somebody takes a hot bath. If it leaks again I suppose I will need to replace the entire shoe, horizontal pipe and the drain in the tub. I am a little nervous replacing it though because my tub is so old and I am not sure if the new drains will fit properly.
