I purchased my home 3 1/2 years ago with the pool and it's equipment included. I have been able to find, troubleshoot, and repair most of the equipment through online research. However, I cannot find my chlorinator listed anywhere online! It is leaking from the back retainer area. It appears that this in considered the Control Dial Locking Pin (according to a newer model, the 6700, I found online). I think I just need to replace the rubber o-rings and find a replacement locking pin (the one that does in there went missing recently somehow). Any advice?
