This genuine OEM sourced replacement part is designed for use with pressure washers. If the pressure washer runs too long with out the release of water from the sprayer, the water will heat up inside the pump. Once the water gets to a certain temperature the thermal valve will open and release the pressurized hot water, to protect the pump. If this happens too often you have a greater chance of damaging your pump. This valve consists of one (1) metal and one (1) plastic piece. To complete this repair you will need a wrench.

after doing all the simple part changes, the washer still didn't have pressure.
Following the directions on the videos at e- replacement parts
I then took the pump off the washer.
Dissembled the pump, cleaned everything
Changed a few o-rings.. Use o ring grease
Reassembled the pump and attached it to the base of the pressure washer.
Works like new now.
I'll be looking for broken pressure washers at garage sales. Now that I know how to fix them it will take half the time.
Some things to look for before disassembly.
1. Debris in the water inlet, especially if you don't have a screen, get one.
2. Debris in the valves after disassembly
3. Take note and mark with a sharpy the direction of how to reattach the pump to the base. On mine, theirs only one way it will go, but you also have to get the key lined up when inserting the drive shaft. This will save some time and frustration.
4. Take everything apart and lay everything out on a clean rag in order for reassembly
Good luck, this was a relatively easy project.
