can anyone tell me if this is normal?
I have an Autopilot Digital providing Chlorine for the pool. For some time now, I have been getting bubbles coming out of one of the return nozzles in the pool. i thought at first that there must be an air leak somewhere in the piping, but various amounts of silicone sealant, smoke sticks and various other efforts to find the leak have come to nothing. What I eventually narrowed it down to was the pool pilot cell horse shoe....But still to no avail to stop the air coming in to the pool.
Finally I decided to disconnect the cell electrics and run the water through without producing chlorine....and voila, no bubbles anymore.
My question (after all this rambling); is it normal for the cell to produce "gases" along with Chlorine? Has anyone else experienced this?
any help would be much appreciated.
