Pictures of a pump that seized.

We had to cut the pump apart to remove it for replacement.

Most pumps just slide off.

These three holes are were the check valves go. They are broken and melted caused by engine running with water in the pump boiling. To prevent this shut the engine off when not using or squeeze the gun trigger to keep water flowing once every 30 seconds.

Repairs like this will cost over $100 or even a new pump.

Things like this are not warranty.
