Hello, this is my first post and I sure can use some help.
Here is the scenario
My bathtub drain leaks at the seal around the shoe (the little elbow with the flange on it that is on the bottom of the tub that the drain screen in the tub screws into)but only at specific times and I have not been able to recreate the leak.
It doesn't leak when the tub isn't being used
It doesn't leak when the shower is being used
It doesn't leak if I fill the tub with cold water and let it sit.
It doesn't leak when I drain the tub.
It doesn't leak if I fill the tub with warm water and let it sit.
It only leaks if one of my daughters or my wife takes a hot bath.
There is no overflow screen in my tub so the only place it could be leaking from is the drain because I put a pan directly under the drain under the tub and it fills up with water.
This is what I replaced so far...
I replaced the gasket that goes under the tub between the shoe and the tub bottom flange.
I originally put another gasket inside the tub between the tub drain and the tub but it elevated the drain and the tub leaked.
I then found out that was incorrect so I removed the gasket and used plummers putty. I ran the shower for a while. Bone Dry. I filled the tub with cold water and let it sit for an hour. Bone Dry. I drained the tub. Bone Dry. I thought I had it fixed. My daughter went up and took a hot bubble bath and when she was done I ran in the bathroom and checked the drain behind the tub and the pan I put under it just for safety had at least 16 ounces of water in it. I then unscrewed the drain and put alot more plummers putty around the drain hole and around the drain flange and screwed the drain back into the tub. I took a shower today and it was bone dry but I suspect as soon as somebody takes a hot bath its going to leak again.
I checked for cracks in the tub. There are none. I even had my wife walk around the tub while it was filled up with water and the tub is completely solid with no cracks or movement.
Any ideas would be greatly appreciated!
