Just bought a house with an indoor pool and I am learning as much as I can about pools. On top of all the honey-do's of moving, unpacking, dump runs with cardboard, kids, work and re-re-re arranging furniture. I have to maintain a pool of which I know absolutely nothing about, other than it is like a big fish tank I have to control the water quality of so the fish don't all go platinum blonde, albino, red eyed whining zombie on me. The previous owner gave me a two minute shakedown on what I needed to do to maintain it. "Flip this breaker, Turn this valve to here, turn breaker on, run for a bit, shake this stuff in like this, this goes in there, don't mess with them, Blah Blah Blah.... Make Sense?" Ssssure! Which Pretty much was translated into the, "watch your uncle pull a quarter from behind your ear" Trick when it came time to get behind the green curtain and make the wizard talk.
So a million questions to ask and answer. Google is a b-e-a-u-tiful thing when you need a question answered. Most of them have been asked before so It's pretty easy to get an answered. The only questions I have at this point that my google-fu isn't finding is: The previous owner never used the Spa and said that we could only run one at a time? I have fiddled with all the valves and managed to fill the spa from the pool. Upon doing so I have found that two of the four jets just dribble if that and the other two were very strong. When the spa was filled to a good level I shut the Pool suction and return lines down and opened the spa return line. At this point I should have been filtering just the spa. Right? The pressure gauge on the filter went from around 12-15 PSI to 30 PSI, and the two working jets would pulsate along with a gurgling sound coming from some 1.5" vent line(?) that goes up through the tile and out the wall. The valves took me a second to figure out and I'm still a little unsure I am doing it correctly. The ball valves are a no brainer, the two jandy 3 position valves are where I'm kind of unsure if I have them right. The spa Definitely has some issues with clogged or fubar jets. Why can't I filter both the spa and the pool at the same time? When I try to, the water gets sucked out of the spa and into the pool. Why would somebody set it up that way in the first place? What do I have to do here?
Here are the pictures of the valve setups. This might help eh?
