[Help] PVC T/Resevior Project

I need a bit help with my PVC T/ Resevior project

I saw this...



but its size is 3/4" Clear PVC Adapter MPT x Slip

I know what is NPT... and also pipe size...

NPT: National Pipe Taper Thread
A sealant compound or Teflon tape must be used for a leak-free seal.
FPT: female (internal) National Pipe Taper threads
MPT: male (external) National Pipe Taper threads

what is that 3/4"? for the length of the PVC? or it is 3/4" NPT?

The way you wrote it and also judging from the picture, it's 3/4" Male pipe thread x 3/4" slip fitting. That's for a 3/4" standard (pvc size) pipe to slip into and glue into place, so that would make it about 1" ID (to fit a 3/4" pipe's actual Outside diameter).
From the pic, I'd say that cavity on the right is about an 1 1/2" deep.

My vote too.

If you mess with this stuff long enough, you just know.

Diggrr is right on.

I also built several airtraps using PVC fittings, and "3/4" indeed has an ID (inside diameter) of 1". You can find actual specs on those at McMaster.com .
