A few small setbacks last night. Drained the sump:
I guess I cracked another bulkhead. In the sump this time. One of the returns was leaking at the bulkhead.
To save on space - I am plumbing the Waveline DC12000 returns like this: 1.5" threaded Bulkhead / 1.5" Close Nipple / 1.5" Threaded Spears True Union / Waveline DC12000 / 1.5" threaded / Slip Spears True Union. I must have over-tightened the 1.5" Close Nipple into the bulkhead and split it. The biggest surprise though - the 1.5" threaded union threads perfectly onto the outside threads of the DC12000's inlet.
I also plugged in the Tradewinds 1/2 HP chiller to get the settings done last night (after first purchasing it on April 2016). The Temperature controller wouldn't work. Called up Tradewinds last night for some technical support and they said they'd ship me out a new controller. Got to admire that awesome support. Anyone having thoughts about a chiller - do consider Tradewinds.
While I have the sump drained - I think I'm going to plumb in a 1.5" street 90 on the recirculation pump bulkhead so I can draw almost all water out of the sump for water changes. The bulkhead sits about 1.5" above the bottom of the sump now and leaves about 20 gallons in the bottom (I know because I bailed it out last night Haha).
I'm also thinking about re-building the return outlets on the seaswirls. I had pre-drilled the side outlet 90's for siphon break with the old internal box. I added an additional 1/2" height to the internal box so the sipon breaks sit too low. Rather than drill an additional hole - I think I will extend the outlets further into the water and drill a siphon break further up.
