Geo-Flo Products’ new ETL-listed flush cart may be used on a 120-volt 15-amp circuit and is listed to UL standard 778. The flush cart is compatible with common antifreezes such as propylene glycol, ethanol and methanol. An optional 1-micron filter now is available for installations where clay and fine sand may be present in water. The additional filtration typically would occur after the ground-loop system has been flushed with the standard 100-micron filter in place.
