This is a drain plug for different models of pressure washers. It is used to seal the check valve for the engine of the pressure washer and features an O-ring that can deteriorate over time. Failing to replace the drain plug can result in water leakage from the pump, potentially causing damage to the pump and surrounding parts, and leading to pump overheating and seizing. To replace this drain plug, you will only need a few tools such as a screwdriver, Allen key, a set of pliers, and a utility knife. First, remove the pump from the pressure washer assembly using a screwdriver or Allen key. Then, disconnect the detergent hose by cutting it with a utility knife. Gain access to the valve(s), which may require you to use a screwdriver and/or hammer to remove the covering plate. Use a set of pliers to rotate and loosen the drain plug and remove it. Apply silicone grease to the new drain plug before installing and securing it. Reinstall the metal plate covering, reconnect the detergent hose to the pump, and reinstall the pump. Monitor your pressure washer for any leaks or other issues with the new drain plug installed.
