Tub drain replacement

So here's what I'm dealing with and I'm confused.

My tub was leaking from under the tub. I believe it's called the 'drain shoe' and the gasket that was in place between 'drain shoe' and bottom of tub.

Took it all apart, and tried to put it back together.

However, for some reason, my drain basket - does not reach the threads on the 'drain shoe'. Upon deeper inspection, it appears that there was a ring (let's call it adapter - correct me if I'm wrong) with external and internal threads.

The drain basket threads the internals of the adapter and the externals of the adapter thread into the drain shoe.

So now, I've replaced all the necessary parts. I have the drain shoe, thread the adapter in like 2 threads, slip over the new gasket, push it up to bottom of tub, and from top of tub, I tighten the basket.

I get it tight and then 1/4 turn...POP! Adapter ring is on the bottom of the basket, and is no longer threaded to drain shoe.

What's the proper process for this?!?

Driving me nuts - any help would be great!

Try putting the basket onto the adapter before screwing it into the shoe.

Like Dan said above, that should do it. If still no luck, try screwing in that adapter first, just enough where it's catching the threads, do not tighten adapter all the way down. Then put your basket in and tighten it down all at once. See if that helps.

Don't forget your plumbers putty and new rubber gasket. Check for leaks, should be good to go, unless it got cross threaded.

OK so it's should look something like this...

The only problem, if I remember from last night...was that when you thread the basket clock wise into the adapter, the adapter spins counter-clock wise, thus breaking the connection into the shoe.

I'll try again with the adapter on the basket first..(Id on't rember if I tried this approach or not)

justintoo, looks good. Nice graphic.:thumbsup: They should all screw right in clockwise unless you got one that's threaded CCW or crossthreaded. Not likely. Also, just wanted to make sure, plumber's putty goes around under the lip of drain only not on threads. Check out this video when you get a chance. Not your tub type, but uses pretty much the same procedure. See if it helps you any. Thanks for watching.

Let us know how everything worked out for you or if you need anymore help. Thanks.

I'm discussing this while I'm at work with a few co-workers.

I described a problem I had when I removed the overflow pipe and how the screw eyelets were not lining up correctly. Also about how when I dropped in the basket, it wasn't long enough to thread the drain shoe.

I'm think that I have a plastic type tub just on top of an existing cast iron or some type tub....

...and that is why (my BIG problem) is that I couldn't get the shoe to thread. I went and bought a PVC conversion kit, and the screw holes for the overflow bracket didn't line up and basket couldn't reach the shoe.

That pic above is from the bottom of my tub (which is plastic on top inside the tub) and shows how the basket does not extend through the drain hold opening.

In your picture it looks like the adapter is stopping you from pushing down on the drain to get your depth take it off and putty the underside of the drain..The adapter needs to be tightened to the drain shoe first that will give you your height tha install the drain from the topside onto the adapter and tighten which will tighten both at the same time. Teflon tape the adapter and some dope too just to make sure it doesnt leak, i would slos dope up the end of the drain as well..

Ok, so you have a plastic tub liner that is installed/refitted over a cast iron tub. Sorry, I didn't see that in your original post.

Is this something like the kit you bought?

something like this

Toss that complete assembly and buy a new one not that expensive that adapter is not part of any tub show kit, its a drain replacement adapter sold in a refinish kit. dose not belong there.
