Review on Upgrade Your Bathtub Drain With Dorence "Lift And Turn" Bathtub Drain Kit - Easy Installation And Quality All-Brass Construction by Kevin Ballard

One star off for casting flash, see below.If you have an older bath drain this may be what you need. I removed an old drain from an early '60's vintage house, the old drain is on the right in the picture. It is 16 threads per inch and was installed with the brass adapter below it, which is 16 tpi both on the ID and OD. Difficult to remove and separate because of corrosion. The old drain is 7/8" deep, the one described here is 1-1/4" deep but that wasn't a problem. I was able to clean and reuse the old adapter, but this time used Teflon tape thread sealant. Note, more modern drains are 14 threads per inch and incompatible with this drain.I took one star off because the standard dumbbell wrench wouldn't fit in until I filed casting flash from the ID at the bottom of the drain where the "cross" is. Otherwise the fit, finish, appearance and quality are fine and it functions as advertised. You may need an adapter, available in brass and probably polypropylene. Again it is difficult to find exactly what you need. I heated the old drain then dropped it in PB Blaster to soak overnight, then wrapped an old leather belt around the outside of the old adapter and hung a pipe wrench on it.The bathtub drain thing is confusing for DIY'ers. If you have plastic drain pipe this is probably not the drain you need.
