The problem is that there is a build up of pressure causing ruptures in the water line on the geothermal line. The plastic drain valve of a Rusco filter has split twice. It was replaced with a brass drain valve, the pressure then went on to split the solienoid. The company that installed the unit is going to add in a pressure relief and a hammer(something), and see if this solves the problem. They haven't experienced this before and its the first time they hooked up a geothermal system to a Constant Pressure drive, they normally are used to working with the well tanks.
Has anyone seen this type of thing before? If so can you describe what was going on so I can relay it to the installers? Will doing the work on the geothermal side push the pressure to the water lines in the house causing ruptures there?
Any help would be appreciated, the installers seem pretty good but they are stumped on this one and are calling a few different places to ask around about this problem.
