You know your chiller is strong when...

[Aquattro]

So my chiller pump was crapping out, low flow, etc. I picked up a new pump tonight after work, installed it, but no water. Figured the chiller was plugged with crude.
I disconnected it (a big job, it's plumbed outside) and tried to back flush it. Nope, nothing.
On closer inspection, I discovered the entire cartridge that the water flows through was frozen solid. One big block of ice. Crazy!! Had to flush it with hot water for 10 minutes to thaw it out. Now that's a chiller!!!
