What it delivers
The SafeTech STTE-2080 Tankless Flush Kit is a flush kit for descaling a tankless heat exchanger.
The pump circulates vinegar or a descaling solution through the heater from a bucket for about an hour, connected to the service valves on the hot and cold lines.
Rinnai's flushing guide uses 4 gallons of undiluted white vinegar and up to about 45 minutes of circulation, at least once a year; its SENSEI bulletin asks for at least an hour at 3 to 4 GPM. Other makers set their own interval.
Listed details: features: Limescale Removal and Descaling; material: Metal, Plastic; model: STTE-2080.
The listing gives a weight of 12 lb and bucket in the box.
