This the 2nd replacement pump I have put on my pressure washer. The original pump froze and cracked the pump, although I had attempted to ensure it was drained before winter. Since then I have had to store it in a room where it does not freeze. The replacement pump worked for 2-3 years before it seized...assume it got some kind of contaminants in the input line. Replacing the pump every 2-3 years is much cheaper than buying a new pressure washer.
