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

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?

I am assuming that you merely destroyed the plug portion of the cleanout. *A
part like one of the ones shown hehttp://www.plumbingsupply.com/cleanoutplugs.html

I am betting you need a 2" cleanout plug. *The actual thread to thread runs
about 1/4" less than the "call size". *Most likely a 2" PVC from the BORG
will work just fine. *You may not be able to buy just the plug at the BORG,
you may have to buy the whole adapter.

Threaded pipe size traditionally refer to the bore of the pipe.
However the bore dimension varies slightly because each pipe size
comes in a variety of wall *thicknesses. So a pipe of 1.75" ext,dia
will be 1.5" bore.

1.5" NPT is 1 13/16 across the lead thread and tapers a tad bit
larger.- Hide quoted text -

Why not use a compressible plug, it fits loosely in the opening and
then you turn a handle to compress the plug so it spreads out sideways
and fills the opening?
