How do you winterize a pressure washer pump to prevent freezing damage?

When winter approaches, freezing temperatures can crack your pressure washer’s pump, turning an expensive tool into scrap metal overnight. To protect your investment, you must completely flush out any remaining water hidden inside the system. Start by disconnecting all hoses, then pull the starter cord several times to force out trapped moisture. The most critical step is injecting a specialized pump saver or anti-freeze lubricant directly into the water inlet valve until it exits the discharge port. This chemical solution prevents internal seals from drying out, lubricates the pistons, and guards against catastrophic freezing damage. Always store the winterized unit inside a climate-controlled garage or basement, safely away from freezing outdoor temperatures and harsh winter weather.
