I dont know if my chlorinator is working correctly. I put 9 pucks in it on the afternoon of July 10th. They are still in there. (They have shrunk some) When I take the top off there is water in there. So today I started taking the tubes off. On the outlet the water from the pvc came out. When I took off the chlorinator tube (outlet) no water came out. I figured the pressure would be pushing it out. So then I took off the hose from the inlet and again no water. I thought this was normal because the pump sucked the air in losing prime. Do these things run on vacuum pressure. I really think these pucks should be gone by now. Since it was new I was doing a test run because I am leaving for the weekend and was gonna count on it to chlorinate the pool. Now I'm not so sure.
