What This Part Does

The 224775 Drain Valve Kit controls the flow path during priming and provides a safe route to relieve line pressure before service or tip changes. Worn seats or stems can cause weeping at the drain, pressure creep, or difficulty holding spray pressure—replacing the kit restores proper sealing and control.

Installation Notes

• Shut down, engage trigger lock, and fully relieve pressure per the GM 5000 manual before service.
• Clean threads and apply the manufacturer-approved sealant where specified.
• Inspect the drain hose/line and O-rings; replace if cut, flattened, or chemically swollen.
• After installation, prime with water/solvent (as appropriate) and check for leaks at low pressure first.
