Check valves are to keep water from back flowing into the pump, you want a ball valve to adjust the flow rate from the pump.
I think the stand is level overall. but where the tank sits on the stand the front left corner is slightly suspended, i know that could possibly cause the tank to break. i should be able to shove a shim between the plywood surface and the frame. i am kinda worried that might creat a pressure point though.. Any thoughts?Do you need to shim the stand? Or the tank? It's okay to shim the stand -- mine is shimmed to make the tank level.
Thank You! i was honestly not sure when i started this project if i would finish it. Ive never done something like that before.Wow! You did an amazing job with that!
