Plumbing shopping list?

[rishu_pepper]

So far I have these in mind, as far as shopping list goes:

3x bulkheads (two for drain lines, one for return)
4' PVC pipe (for the two drain lines)
4' flex PVC (for return line, I want to go this direction to lessen horizontal travel)
2x true union gate/ball valve (for main drain line flow adjustment, and one for return flow into refugium)
1x tee valve (for teeing off flow from return to refugium)
2x union (one for return pump, one for emergency drain line)
PVC glue
teflon tape for threads

I do not plan to have a manifold at this time, since I have decided not to run biopellets, so I don't have any reactors other than a TLF for RowaPhos, and I'll just run that on its own.

*stupid question* 1.5" size for all the bulkheads/pipes related to the drain, and 1" size for the return pump line?

Let me know if I'm missing things
