I had to hacksaw out my cleanout plug yesterday. Now I can't find a

The size is 1.75" inside diameter. Yes, you read that correctly.

Nobody carries a 1.75" ID cleanout plug. And a 1.5" rubber one won't
fit (neither will a 2" - I purchased both).

Furthermore I can't find ANY info on the net about 1.75" threads.
House was built in 1955.

Am I hallucinating?


In 1955, 1 1/2" was a "normal" drain size before codes were changed
and 2" became the norm.
My best guess is that you have 1 1/2" fitting.

Was this plumbing arrangement for "back to back" or "side by side"
sinks?

Get a 1 1/2" plug.
If they a 1 1/2" tape or thread chaser, rent it so you can clean up
the threads.
