Another professional drawing of the return plumbing. Rough idea anyway.
Here is the plan for the manifold off one of the return pumps. I am using 2 x Vectra M1 pumps @ 2,000 gph.
1. Carbon
2. GFO
3. Chiller (optional)
4. Fuge
5. Open / Extra
6. Open / Extra
7. UV
In regards to the UV, I've seen it done both ways. What is the downfall of running a UV off a manifold? I know they require a specific flow rate but I'd prefer not having another pump if possible.
