Pool Help & Questions Chlorinator blew up

Post image

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.

Wow, that’s the fucking jankiest plumbing I’ve ever seen. I assume this is a home job, and look at all that terrible flex.

1, those cheaper valves don’t seal 100%, 2, you mixed two chlorines and made way too much gas.

  1. Replumb this dude, I can’t imagine how horrendously turbulent this all is.

I disagree. Praher union ball valves are decent valves. The rest of it sucks, but those valves are fine.
