One of the most important steps in installing a closed-loop geothermal systems in the flush/purge process. This is the point where we circulate water using a temporary purge pump and tank to remove all air and any debris that may have gotten into the system during construction. Trapped air and debris in the system can potentially cause damage and cause the equipment to operate inefficiently. Our experienced technicians know what to look for before calling the system clean. We can perform this service on new or existing systems.
