Review on Efficient and Simple Kelaro Tankless Water Heater Flushing Kit with Vinegar Descaler by Onur Donovan

Everything you need to flush a water heater except a few gallons of vinegar. Connect, align valves according to instructions, add vinegar and leave to work. It pays for itself the first time you use it because there's no need to call a plumber. Make sure your heater has flush valves (should) otherwise you'll have to install them. In addition, regardless of the rinse, do not forget to clean the cold water filter. If you really want to save money, the pump and hoses come standard and can be purchased separately for even less money.
