The cell and the flow switch are obviously installed correctly.. This means the flow switch or the cell itself must be bad. I say this based on the fact that you said you had good flow back to the pool.. Is your spa overflowing into the pool ok?
Got a new SWCG today. Working perfectly. It was reading 2500ppm. The tech used his meter and it read 2600ppm. I use the Thomas test kit on Saturday and it read 3000ppm. I assume the SWCG and the tech's meter are more accurate than the Thomas test kit? Anyway, added 2 bags of salt and now SWCG reads 3000ppm. 13,500gpm. Add another 40lb bag?
Sorry, yes I have the Taylor kit. Don't see how it can be more accurate than a digital reading. The salt test kit measure in increments of 500ppm. Each drop is 500ppm. So if you actually have 3050ppm of salt, the Taylor kit will say you have 3500ppm, correct?
Thanks....as just setting up trying to get a good base. Water temp 59 and SWCG reading 2850 so I will go ahead and add another bag this morning. Trying to get to magic 3200....PB coming by Friday and we will test everything and add stabilizer.
