I am currently working up a write up on plumbing a tank. I see a lot of post looking for advice on how to plumb a tank. Is this worth my time? If I post it I would like it to become sticky. It would go into head loss, pump size, different styles of drains and how they work, PVC flow rates ect. Other forums have this in there DIY section. I thought it would be nice to have a reference here. RC has a flow rate calculator. It is out of date I am not that smart to create my own. But I am sure someone here is. let me know what you guys think. Any help with this would be appreciated.
