The only catch is the 3 RD3's would cost as much as 2 A100's... But I like the idea of running the A100's controllers as they were meant to, in tandem working together. I could easily work the return plumbing to maximize what the programming could allow for.

Also, I plumbed some spa-flex between the overflow and returns and am getting a slow drip from both bulkheads on the top sump. I am going to cut out the spa-flex, grab a female/female 2" coupler and new bulkheads and remake the connection with 2" rigid. That should alleviate any weird stress on the bulkhead gasket. Any objections?

One thing that I have found.
If you install the bulkhead gasket dry, quite often it will end up leaking ( dripping ).
I usually pop the whole fitting into a bucket of water just before installation.
You get a way better seal on the gasket and won't have the dripping problem.
