Tankless Hot water Heater Flushed Clean

Largo Green (LG) flushed this Tankless Hot Water Heater (HWH) from years of built-up grime & residue. LG first disconnected the water lines, then attached a battery-powered motor, & setup a closed system of hoses for flushing. LG used 2 gallons of white vinegar run through the closed system for 2 hours. LG achieved a super clean result.
