Simpson Cleaning 7104223 Replacement Valve Kit for Pressure Washer Pumps, White

Works good same as home light style pump check valves

Excellent quality product. Fit exactly in my Simpson AAA pump. No problem, very easy installing and works very well. Definitely very happy with the price and quality of this product and saved me having to buy another pump. Thanks so much for the deal.

Worked great

Fixed my Simpson 4200 Pressure Washer pump to run like new. Easy to install and exact fit for pump. Great maintenance item to keep on hand, as this is the "wear" point for these pumps.

Not the correct part for the water pump. Upon installing them and starting my pressure washer I had No water pressure. Took the pump back off and opened it to inspect the valves I just installed and all 3 inside were broken apart and smashed. They are not the same as the original that came out and seem to be larger in height. Fitment claims fits pump model 520006. Waste of Money amd not the correct fitment for these pumps

Valves fit perfectly in my pressure washer pump. Easy to install.

Quedo muy bien

I have the Simpson MSH3125 3200 PSI power washer with the Honda GC-190 motor, but none of that is relevant. What is relevant is that it has the OEM Technologies 90029 Replacement Pressure Washer Pump kit attached to it which is where these valves go. There are 3 valves on top which can be seen covered by brass caps with the pump on the motor, and 3 valves inside which cannot be seen unless you take the pump off the motor. To take the pump off the motor simply use a hex wrench to remove the three outermost silver bolts, do not remove the 4 matching bolts behind the pump unless you want a mess on your hands (you cant remove 2 of them unless you take the pump off first anyway). Once the pump is removed, remove the caps on top and youll see the valves at the bottom of the cylinders. Flip the pump over and youll see 3 more easier to see valves. Theyre hard to get out, use spray lubricant and long needle nose or a long 45 degree pick and be patient. Once all 6 are removed clean up the cylinders gently to remove any residue from the previous valves. Often they go bad due to heat (running the unit without spraying with the wand) so having residue is pretty common. Then apply a little plumbing grease and slide the new ones in. Re-assemble caps on top, Re-mount pump to motor and off you go. Easy, fast, cheap fix to save a 400 dollar power washer unit!
