Penguin glycol chiller question?

Systems, Gear, & DIY
1

I’ve had the penguin glycol chiller for years. Just turned it on and the pump didn’t work. I pulled it out and fiddle with it and put it back in and then it started up and worked fine. I realized I haven’t changed the glycol in years and it’s getting pretty thick and disgusting. Just wondering:

How often do you guys change the glycol?

What’s the best way to empty the reservoir?

Thanks

The maintenance manual suggests pumping white vinegar through the system, so I would guess pumping out the glycol?

I hope that helps.
