Hi again, newbie pool owner from Dallas here. I have a pool / spa combo, and I haven't had time to talk with a pool guy at the house yet. I see 4 vales coming into the pump, so I'm guessing these are:
1) main drain
2) skimmer 1
3) skimmer 2
4) spa drain
They aren't labeled, but one is off to the left by itself. I'm guess that's the spa drain, correct? It is currently off, and the other three are on. Is that how it should be usually? My spa is just overflowing into the pool.
