WE HAVE WATER! Well fresh water anyways, the system passed the freshwater test, I had two setbacks.
Number 1: Dont just take for granted that the manufacturer put the O rings in your ball valves! Mine didnt and I apparently didnt notice it when I was putting them together.
Number 2: Needed to put an extra half turn on the 2" bulkhead
I never realized just how stressful it can be to turn a hose on. Thank god its over. I still probably wont sleep well tonight.
I have a little more water noise than I had hoped for due to the euro-bracing I cant make my durso's quite tall enough to silence the overflow boxes. The overflows themselves are quiet as a church mouse, Ive also got a little bit of a hum from the Sequence but I figure that is to be expected. Not too much louder than a freshwater air pump, kind of sounds like a fan. I figured the flow would be a little stronger but it should be alright for now.
