Thats good.I wasn't sure if you were going to use unions and then tighten them up again.You can also cut the pipes and use couplings(Would cost less) Unions are better though cause at least you don't have to re glue everything.If your not removing the bulkheads than you can place a bead of silicone on them the first time.Don't over tighten the bulkheads.You are supposed to tighten them by hand.
