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.

Frequently Asked Questions
It is specified for the GM 5000 (Convertible). Do not assume universal fit—always match the part number in your unit’s parts list before ordering.
Persistent dripping from the drain line, pressure that won’t hold steady, difficulty switching between prime/spray, or a valve handle that binds are common signs the drain valve internals are worn.
Follow the GM 5000 manual. Typically, NPT threads require an approved sealant; avoid excess that could enter the fluid path. Torque to the specification in your service guide.
Some aftermarket assemblies list compatibility with Graco 224775. If you choose one, verify dimensions, pressure rating, and warranty implications. OEM is recommended for best fit and longevity.
Not always, but it’s wise to inspect the hose and clamp. If the hose is brittle, cracked, or swollen, replace it to prevent leaks at the new drain valve.
