6" PVC PIPE
 

Find a local Plumber the smallest one you can find that does commercial
work. He might have a couple of pieces of scrap.

Try an ag/irrigation outfit.

Try your local city water/sewer department. they probably trash pieces that
small every day.

BTW, You never said whether you need schedule 40, sched 80, 3034 or what. If
you need to have fittings, joints etc.

Good Luck

this, in spite of the trouble it's caused me. Being shot out of a cannon
