Finally got the chiller installed. I am using a ¾ HP Tradewind chiller. Yes over kill for the tank size, but this will reduce the cycle time and save money in the end. This is the last major plumbing operation needed to start water testing the system.
The chiller is placed in the attic directly above the tank. I had an AC pan building in case there is a leak to catch any water and protect the drywall ceiling. The pan is piped to the AC condensate overflow that leads outside. This way if there is a leak I can see it and take action before too much damage happens. A few simple vales for the by-pass, reduced the pipe size and back down to the tank feeding the returns.
After the install I did a water test. Had a few minor leaks at the unions which a pair of channel locks and a quick turn fixed with no problem. What I did not expect where leaks at the flexible PVC connection. Turns out the Flex PVC is just a fraction smaller than regular PVC hard pipe. This resulted in regluing a hand full of connections. Never had this problem before. So a learning experience for me.
Good news is retested, no leaks, chiller cooled the tank with no problem down to 60 at one point. I did this to over stress test the system. I then ran the tank for a week set at 74, all systems go.
This allowed me to monitor the water levels in the sump, the tank lost around 2 to 3 gallons of water a day. RO/DI is on the list for install.
Hope you all enjoy, feedback and comments are welcomed and reqested.
