Hi everyone, I am a first time pool owner and we had our pool completed in Aug 2019. I have been managing the pool on my own since October and have come up with a few questions after reading pool school and scanning the forums. Happy to separate these questions into different threads/forums if it helps.
1) Calcium Hardness: When the guy opening the pool at the start took me through all the numbers he recommended that during the "winter" in Charlotte (rarely gets below freezing and so far the water hasn't gone below 45 degrees) to keep the CH around 200, saying if you let it get up to 300 it may cause scaling. The local pool shop paper says a target range 200-350 (though they don't differentiate by pool type). TFP says 350-450 for SWG. Why the difference? And do you think there is a chance of scale when the water is in the 40's if I go up to 350? Also, given how little my SWG appears to be working in the cold (In addition to the SWG I am using 12.5% "Pro Chloronizer" bleach to keep the FC around 2 since we are not using the pool right now) should I consider this a chlorine pool for chemical level purposes during the winter?
2) SWG - I cant find much literature on the temperatures SWGs stop operating at but it doesn't seem like mine is working much over the winter. I run the pump 23 hours a day, mostly on 18% but with 3 hours on 85%, during which I run the SWG at 100% (so the SWG is running full tilt for 3 hours). Any recommendations on if i should increase the amount of time I run the pump at higher speed with the SWG on or given how cheep bleach is should i keep doing what I am doing till it warms up and the SWG becomes more efficient? Does anyone know if SWG stop working all together when water is under a certain temp?
3) Valve install: I am wondering if one of the valves for my pool was installed backwards. In the attached picture you will see the red square marking the inlet of the valve that I think is installed incorrectly. The way it is installed the water is flowing out of this port, not in. The reason this is an issue is because the way the valve is installed I can't divert all the water to the cleaning robot pipe. When I open the valve to direct water to the robot pipe it also goes to the branch that sends water to my pool returns or the spillover of my spa (the lower section of the picture). If I rotate the valve 180 degrees from how it is pictured in the photo I would stop water all together (which seems like a dangerous design since pressure would build up). Right now when I set the valves such that water goes to the cleaner and the spillover there is not enough pressure to get the cleaner wheels rotating fast enough (the cleaner directions recommend 28 rpm and mine is less then 20). I asked my pool builder but haven't received a reply. Anyone agree with my assessment?
4) Heater Display - my Hayward heater is showing an "Sb" which indicates a keypad failure (see second attached pic). I have tried to "unstick" any stuck buttons on the keypad and it doesn't appear there are any stuck. I have also shut the heater down (turned off the electric) and restarted and the problem persists. The heater still works via the Omnilogic controller so its not a huge deal and scanning the forums this seems like a common issue and is resolved by replacing the display panel. Wanted to see if there were opinions on chasing my builder to fix it or if its not worth the hassle given the heater still works and it might break again down the road.
Thanks!
