Thermal Relief
”
Definition:
A technique used to reduce the buildup of high-temperature water within a powerwasher pump caused when the spray gun trigger is closed. Cycles water through the pump when water reaches maximum water temperature. Some of our models have pumps designed to work with the water temperature of 145ºF, 160ºF, and some as much as 180ºF. Warm water will discharge from the pump onto the ground. This system prevents internal pump damage.
