I'm looking for some help. I'm new to this whole pool thing...we just moved into our new house last week and have a question around our Pentair IC40 Chlorinator.
The chlorinator is reading high salt (excess of 4200ppm) while testing the water at our local Leslie's Pool Supply store is reading 2700ppm (2 seperate tests...different trips) which is actually low. The pool was installed 5 years ago and I'm guessing that this equipment is original from the install.
A little background, last week I took a sample of our pool water into our local Leslie Pool Supply store to be tested. The test results came back with 1600ppm and no chlorine. The IC40 on the other hand was reading 'good' salt levels (3000-4200ppm). The cell status light was blinking at this time, so I cleaned the cell using the appropriate technique. After reconnecting the cell status light stopped blinking. I then added 5 bags of salt (~17k gallon pool) and the high salt indicator has never turned off since then even though the test says 2700ppm. After the shock wore off we are now back to 0 chlorine.
Is this an indication of a bad cell? Is this a calibration issue or a issue with the test done at Leslie's?
The previous owners had a company come out and test the water back in March and the pool tested at 3000ppm and no salt was added since then other than the 5 I recently added...so I have a hard time believing the salt is really above 4200ppm. With the cell reading that high though it's not going to try and produce chlorine.
