Looking For Pieces of

[TripleT]

Just picked up a 1.5" ID bulkhead to build a prototype surge tank. One side is threaded and the other is slip joint.

Does anyone have a piece of 1.5" ID threaded about 20" long that they have as left over?
Cheap or for future dibs...

Also, need a piece of 3" ID with cap, about 20" long.

And for the piping back to the tank, where does everyone pick up their fish safe plumbing in Calgary?

Thanks,
Terry
