I'll be using hayward bulkheads for my tank.

1) What is the difference in a PVC, CPVC, and PPL bulkhead? Which material is recommended?

2) For the seals, what's the difference between an EPDM and FPM?

3) For the end connection, which would you choose:

Socket x Thread, Thread x Thread
Socket x Thread
Thread x Thread
