A friend of mine has one that is used with a 28K gallon pool. The product literature says it's for pools up to 12K gallons. He runs his pump 13 hours aday with the chlorinator set to 100%. Is there any situation where this is OK? Did the pool builder know something I don't? I told him I thought this was wrong but he has a ton of faith in the builder so he's reluctant to take my advice. Pool is less than 2 years old with all Jandy equipment. Is there a 3 year warranty if you buy all Jandy equipment? I think he got hosed on this.
