Frequently Asked Questions

Yes—if your sprayer’s fluid section is the GM 7000 with pump model 236533, the Graco 236565 Pump Piston Valve is the intended replacement. Always confirm with your parts manual.

Hard or failed priming, pulsing/uneven pressure, leaking back through the pump, and inconsistent spray pattern typically point to a worn or damaged piston valve or seat.

It’s recommended. Worn packings can affect sealing and check action. Replacing the valve with fresh packings helps restore performance and extends service intervals.

Yes. Some catalogs use the dash format (236-565); it refers to the same Graco part number 236565.

Follow your service manual for torque values and orientation. Correct seating and alignment are critical to maintain check action and prevent premature wear.
