Our pool was completed in June and when the PB installed the chlorinator it appears they crossthreaded the body of the chlorinator where the valve screws into it to control how much chlorine enters the pool and it had a slow leak. They tried to fix it a couple times but they were unsuccessful. And instead of replacing it they just put the valve on the top of the choloriantor instead of the bottom where it was originally. Seems like ever since that happened I have had way too much chlorine entering the pool even when the valve is turned down to 1 or 2. Is this ok to be on the top of the chlorinator or should I have them replace the entire thing? Sorry for the terrible explanation. Please let me know if more info is needed.
