Very slow progress!
Came down to Mitras vs. Kessil. Went with the Kessil because of its small size, price, and I like the mounting arm. Knowing me I'll regret my decision in two weeks, but so far I like my choice.
The overflow. I used stockman-like standpipes due to a lack of space. If it doesn't work out I'll try another design.
Cut out a few teeth and fed the loc-line under the eurobrace.
Not quite finished the plumbing. Still need to build something to support it, and I need to finish the return plumbing. The DC5000 has a weird sized outlet, 1.25" and I couldn't find a PVC 1.25"-1" threaded bushing in Vancouver. I have accepted I'll have to use the 1.25"/1" barbed adapter that came with the pump, which I'll attach to hard plumbing with a 1" barb/male threaded adapter.
Still lots to do.
