MTD Pressure washer leaking water
Is your MTD pressure washer leaking water? The most likely cause is a worn or damaged pump assembly, especially if the pressure washer is more than a few years old and used often. A pump rebuild may correct the problem on a newer or lightly used machine, while an older pump may need replacement. If the leak is coming from the pump, inspect the pump seals and related components for wear. The pump itself may also be cracked or damaged and require rebuilding or replacement. Another possibility is the thermal release valve, which can open during normal operation if the pressure washer runs without spraying water. Water trapped in the pump heats up, and the valve releases it to prevent overheating. This can look like a pressure washer leaking water or a pressure washer leaking from the pump, but it should stop once the machine cools and is used correctly. Shut off the engine and water supply before inspecting parts. Enter your model number to find the exact replacement pump assembly, pump, pump seals, or thermal release valve for your MTD pressure washer.
01 - MTD Pump Assembly
You may need to rebuild or replace the pump assembly. If the pump is more than a few years old, and you use the pressure washer fairly often, replace the pump assembly. If the pump is relatively new, and you don’t use the pressure washer often, either rebuild the pump assembly or replace the pump seals.

03 - MTD Thermal Release Valve
The leak could be due to the normal operation of the thermal release valve. The thermal release valve allows hot water to exit the pressure washer if the water temperature becomes excessively high. If the pressure washer is left running while it is not spraying water, the water in the pump will begin to heat up. When the water temperature rises above the acceptable limit, the thermal release valve opens to allow the hot water to exit the pressure washer.
