HELP ! Tub Drain not long enough !


I ahve a 60 year old cast iron tub. I am completely replacing the drain and overflow. Here is my problem...the drain itself that goes into the drain hole and the threads into the part below that is positioned just under the drain hole...The male threaded part of the drain is not long enough to reach the femail part below...the tubs thickness and the shape of the drain hole. I can get maybe 1 05 two threads started but if i try to tighten it pops out of those two threads and comes apart. A plumber at a local supply house saod they used to make a longer one for marble tubs as these tubs are thicker. He also suggested using JB Weld as a plumbers thread sealant...catch the two threads I'm catching and let the JB Weld hold it all together mechanically.


HEEELP ! I have a ome inspection in 6 days

Are you trying to screw it together while the trip waste is all put together. Try taking out the piece that the strainer screws to and attach it that way.

More on tub drain


I am using a high quality brass assembly...I have about convinced myself that there might be a hardened gasket on the underside that I need to remove...I am going to hit the underside with a surface grinder and see if it is metal of a gasket...sure feels like metal. The thread extension on my drain is almost exactly 1 inch...I think i need alost 1.5 inches to get teh parts to thread into each other

Re: HELP ! Tub Drain not long enough !


Maybe too late, but a decent machinist might be able to make a brass extension for you.
