This part includes one pump check valve for use with pressure washers. The pump check valve and the piston regulate the flow of water through the pump assembly. It is common for the part to wear out over time, so it should be part of your regular inspection check-list. If you use your pressure washer quite a bit, we recommend having one of these on hand in your tool box.

After a short time running, my pressure washer does not pressure up when I pull the trigger. If I remove the tip from the wand and pull the trigger, I can then replace the tip and the problem is overcome for one cycling or until I release the trigger again.
For model number K2400 HH
Hi Mark, thank you for reaching out. We would suggest making sure the jet pipe is not clogged. If the issue remains, the fault might be with the nozzle, part number FIX10020775. Blocked nozzle may prevent water from escaping, while a worn nozzle will allow too much water to pass through, causing the pressure to drop. We hope this information helps!
