Devilbiss Pressure Washer Pump Leak


I have a Devilbiss Axial Cam Pump Model #PK18219. It has started spraying water out the vent holes on the sides as soon as I turn on the water before I even start the engine.

I took it to a local place and they told me that water coming out those holes means the pump is dead, but after disassembly, I don't see any real wear. I'm thinking about getting the water seal kit, but I'm not sure that's available anywhere.

Can anybody point me at the right parts to replace and where to get them?

Do you need more than just o-rings? Usually you can match up orings at an auto parts store...they're probably metric sizes.

As Mr Cheese mentioned you may be able to pick O-rings up locally.

You can also look at a parts diagram and purchase some parts here;

Just enter your pump model number in the model number box,

M&S Service Company - Parts Search > Search

If it's just O-rings you need keep in mind that there could be a problem with the unloader. The unloader bypasses water pressure when the wand trigger is released, When this unloader fails/sticks pressure builds up in the pump and blows the O-rings.

Good Luck
