I've noticed a slow but steady loss of salt in our pool. In early August our level was 5000 ppm (recommended by ECO-matic) and now (late November) is down to 3000 ppm. We've owned the house for one year, so we're just familiarizing ourselves with how the seasons affect the pool. I am using the Taylor K-1766 salt kit, so I believe the readings are accurate.
My understanding is that nothing should affect the salt level except for dilution. The sprinkler heads in our sprinkler system do have some overspray on the pool cover, and I believe some water may be getting in by running across the coping. But we only water two or three times a week for about 15 minutes. Based on the salt levels, that would mean we've lost, or poured in, 40% of the water. That would be about 3800 gallons. If it's the sprinklers, that would mean that about 80 gallons of fresh water are getting in the pool during each watering in that period. That seems like too large a number. So, is there a leak somewhere in the system? I don't think I've ever heard the leveler adding water and I believe it's a sound I would have noticed. How does one go about determining what the cause is? Am I overlooking some other possibility? Thanks in advance for your help.
