Pipe sizes and fittings
Posted by D. Marsico on July 15, 2003 at 20:22:06:
I'm looking to replace my pool cleaner. The new one I want to buy has a 1 1/2" male fitting that is supposed to screw into a threaded pvc pipe sticking out of the pool wall.

The old one has a similar fitting and the specifications indicate it to be 1 1/2" also.

However, when I removed the piece and measured it, it measures 1 3/4"??!!??

I'm confused. Is this one of those 2 by 4 things where it really only measures 1 1/2 by 4 but they call it a 2by4?
