FYI - it is Code to paint all exposed PVC in Clark County, NV. Due to sun degradation. The building inspector would not have passed the install if not painted.
Also - you have a tube turn immediately before your SWCG. Pentair recommends 12-18" of straight pipe before the SWCG. I had to re-pipe mine as it was also installed with a tube turn a few inches from the inlet and thus required a much higher (~2100 RPM) flow rate from my VS pump to run the SWCG. By re-piping I got the flow rate down to ~1500 RPM needed to run the SWCG. A large power savings.
Have fun! Has been over a year since our install and still working through minor issues. But great to have a pool to jump in to!
