standard everyday pressure washer pump is not designed to pump hot
water. Pumps are cooled by the incoming water. Most pumps can
tolerate water up to 63°C (145°F). However at these inlet temperatures
there is no room for water heating while the pump is on bypass.
Overheated pumps will
chatter as the water reaches excessive temperatures. Seals and valves
will melt and ceramic pistons will crack. It's always a good idea to install a thermal
relief valve on your pump. Installed on the inlet side of the pump
they open up when the bypass water reaches at 63°C (145°F).

pump will last longer. If you need hot water to clean get a hot
