This part is sourced from DeWalt and is a manufacturer approved replacement part for DeWalt Pressure washers. For full compatibility, please see the "Model Cross Reference List" below. This valve kit contains a complete set of check valves (3 inner valves and 3 outer valves), as well as the rubber o-rings needed for installation. These valves fit in the pump and work together to pressurize the water. If your pressure washer is unable to build pressure or has low pressure, it may be time to replace the valves. These valves are made out of plastic and metal, and each valve is approximately 0.5" in length. These valves are also referred to as Check Valves. There are 6 valves in each kit, which is enough to replace all the valves on your pressure washer.

Installation Instructions

Chance from HOUSTON, MN

Pressure washer would build minimal pressure.

Started by running water to the pressure washer and not running the motor. Started the motor and minimal pressure increase from wand but an increase. Removed the valves which were seated/stuck. Broke 4 of the 6 in order to get them out so really could not see if a spring was broke or damaged. Replaced all 6 valves and it now works great. The most difficult part of the job was removing the valves without damaging the brass. Read more...

This replacement part is a safety mechanism that helps prevent serious damage to you or your equipment. This thermal valve relief is made of metal, and the threads have sealant on them to ensure airtight connection. The thermal valve relief is sold individually. You will need basic hand tools for installation.
