I have a 3-ton Climatemaster closed-loop geothermal system with two 300 foot wells.
I was in the process of having Sonotube footers dug & in the process, one of my well pipes was severely nicked by a shovel. So I opted to have it repaired. My well guy cut out a 2-foot section and heat fused it in place. The system was purged and topped off & works well.
My concerns is we noted the color of the antifreeze had a dark hue & wasn't blue like it was when the system was filled back in April. I also noticed the inside of the piece of pipe we cut out has what looks to be a rust film. I'm not sure where the rust is coming from. Anyone have any idea(s)? I contacted the well guy. He used water that was process through an ion exchange unit & had a ph of 7.5. He said an additive could be added, but is it necessary in a closed loop system where Charter Plastics geothermal pipe 3408-C-3-
dr-11 was used?
