This is for a leak that was noticed last week. Jeff Bartlett noticed a large puddle forming under the chillers. When I went to investigate I noticed that the X chiller water level was low, I pulled off the panels and saw where a small leak had been dripping on top of the radiator for quite some time. I think this explains the difference in the refill logs for the past couple of months of operation. You can also see how there is sediment forming where the leak was evaporating. I pulled the motor and water pump from the chiller body, separated the water pump, and got the seal where you can see the ceramic seal had become chipped. I will try and find a suitable replacement so this chiller will be a functional spare. Meanwhile, the spare is waiting on some new quick-disconnects to arrive as the previous ones had been cross-threaded and I didn't trust them to hold a good seal.
