I see people (even professionals and manufacturers) connect solar pool panels with Fernco flex PVC DWV couplers. My question is why is this done when they are rated for max PSI of 4.3?
Fafco solar panel headers are 1.5 inch female threaded (other manfacturers have MALE thread). So to connect rigid PVC to the Fafco it will have more resistance (smaller hole) compared to using a Fernco flex PVC coupler (larger hole and less resistance). This may be small and trivial but maybe not.
