Plumbing design check up

[diablo243]

Ok all drawing up my plumbing design and looking for comments, opinions, suggestions, etc.

Drain is 1" and return is 1.5" there is a 3/4" water change in and out for my auto water change system. The return has a T that adds an accessory or expansion leg with ball valves.
Thanks all for the input!

Kind of hard to really grasp what you're doing from the image. My recommendation is to use gate valves over ball valves, use unions as often as possible, check valves on your returns, 3/4" returns are fine, and always keep redundancy in mind for safety & failure.

Also dry fit before you cement.

I would like to know more about the Auto Water Change you are planning.
