I just noticed I have a junction box marked "INTERMATIC", ~20 feet from the pool/spa, and 18" above ground. Is this for power lines going into the pool/spa lights? How do I test its GFCI protected? In the photo attached, the outlet box has two outlets, but they don't have power. The pool light...

I like to give more flow from pool drain to skimmer, while keeping the filter pump speed constant. Looking at the plumbing photos attached, any suggestions? In the 1st photo, the pump in the middle is the filter pump. It is fed by main drain+skimmer on the left side and the spa on the right...
