I have a 5 year old salt water pool with all Jandy equiptment. DE filter 60sqft, 13000 gallons, IG, Plaster. The salt cell is not producing chlorine. The PDA shows (no flow) much of the time (although the flow seems to be good). I have narrowed this problem down to 2 possible causes. 1) The sensor when installed was glued in place. This makes it near impossible to clean or service. Could this sensor be too dirty or defective? 2) My pool is under a pine tree and is therefore very dirty requiring very frequent filter cleaning (every 4-6 weeks uggh although I have gotten it down to about 20 minutes all told). There was no backwash valve installed so the only way to clean it is a complete cleaning. The grids look to be in good shape but when cleaning they hold water longer than I think they should if I put water in the water inlet.
Which is the most likely solution to this problem? 1) install a backwash valve so that I can get a backwards flow thru the grids providing a thourough cleaning of the grids. (I know I should probably do this anyway) 2) Replace the grids providing for a better flow rate. Although the water seems to flow thru my waterfall well (this is my main indicator that filters need to be cleaned) and the pressure in the filter seems to be okay. But the grids do clog up quickly (even adding conditioner is an exercise in patience). 3) Replace the sensor hoping that there is not really a flow problem.
I beleive I have had this problem intermitently struggling to keep the chlorine level high enough. But now I dont think it is working at all. The cell is only about 2 years old and I cleaned it recently. Even with the chemistry balanced out I am still struggling to have a stable situation.
Do any of these theories make no sense or which order should I try these solutions?
Any help would be appreciated.
Thank You,
