I am brand new to this forum, but I just wanted to take a moment to thank all of you for your advice. I was having quite a time maintaining FC chlorine in my inground pool and was worried about a possible leak as well. With your help I've conquered both and couldn't be more grateful, to all of you, for preserving my sanity. Im BBB all the way now. Chemistry is spot on.
I am definitely a novice, I am now the sole caretaker of my pool, half way through my third season, and still learning so much. Im now comfortable with fundamentals, however,I still encounter "Houston we have a problem" moments. Could you give an answer if this situation is a normal occurrence or if I have a problem that needs a professional.
I have a Hayward DE filter,36 sq ft fitted with a multiport valve and 1.5 HP single speed pump. Pump and multiport are both 1 year old. We have been getting hit with torrential rains here in Central NJ that has required me to drain the pool of a few inches of water. The following problem also occurs when I backwash as well.
Whenever I set the valve to waste or backwash water immediately rushes away from the pump basket. I am able to complete the waste/backwash process successfully, however, I need to IMMEDIATELY RETURN the valve to filter, and power on the pump, otherwise, if I let the valve sit on "filter" for more than a few seconds, a big air bubble appears in the pump basket. Then when I power on, it takes a good half minute for water to return to the pump and out of the returns. The water then flows strong, without any air bubbles out of the returns. Last week, after backwashing, I returned the valve to filter, it sat for a couple of minutes, while I retrieved the DE out of the deck box. When I turned on the pump, no water, and it took two "power ons" to get the pump to prime. Needless to say, scared the bejesus out of me.
What am I doing wrong? Which leads me to part 2 of my question. I have three diverter valves, I know what they are, however, I was wondering, on what occasion, if any, would these valves need to be turned off? I recall my husband telling me to make sure they are always in the 12 and 6 o'clock (on) position, but I also recall him turning them off on a few occasions, but cant remember for the life of me, why. Perhaps to backwash? Could that be the reason for my pump prime issue, Im eliminating the step of turning off diverter valves?
Thoughts? THANK YOU THANK YOU
