Have used an offline Chlorinator for years. Now, all of a sudden, I can't seem to get it to feed chlorine into the pool through it. Have just replaced the unit with a new unit, including all the tubes and fittings. Chlorinator turned all the way up. Still experiencing drop in chlorine in the pool even through the chlorinator is full of "pucks" and does not seem to be using them. Water does seem to be circulating through the chlorinator as I can certainly feel some pressure in the pipe on the inbound side, and slight pressure in the tube on the outbound side. Any ideas? How can I test if the chlorinator is working at all? Have just shocked the pool and placed some pucks in the skimmers to get rid of the algae and stabilize, but don't want to have to get into this situation again.
Lost a chlorinator this winter when the entire unit froze, so replaced with a new one, and as far as I can see, replaced all the parts that were damaged by the freeze. Prior to this event, best I can tell, chlorinator was working fine.
Would appreciate any ideas on how to troubleshoot the chlorinator to get to the source of the problem. Don't believe it is the chlorinator anymore since I have just replaced it with a new one yesterday. Am taking daily chlorine readings now and am waiting for the shock and the pucks in the skimmer to be used up to see if the chlorinator can sustain a chlorine level in the pool by itself.
Thanks for any advice you can offer.
