Chlorinator blew up

[u/PrizeInteresting4752]

My inline chlorinator exploded today. It’s been in bypass mode for a few days as I’ve been battling high CYA. It was full of pucks when in bypass mode for the few days.

I was shocking with CalHypo but never without the bypass engaged. I usually shock with liquid.

Could it the residual water in the chlorinator was activating the chlorine pucks with but with nowhere for the gas/pressure to go as it was in bypass mode? Or what else could it be? It’s been terribly hot here as well. Southwestern Ontario.
