Frequently Asked Questions

The piston valve controls fluid movement inside the lower pump section, enabling smooth upstroke and downstroke operation. A worn valve causes pressure loss and uneven spray performance.

Check the model number of your pump lower. If it is an L072C0 lower or an Xtreme/XP lower in the 36cc–72cc range, this piston valve assembly is compatible.

Common signs include fluctuating pressure, poor atomization, difficulty maintaining spray consistency, or internal leakage in the pump lower.
