Why Use an Unloader Block?
Mounting an unloader directly to the pump outlet can place additional stress on:
- Pump manifolds
- Pump outlet fittings
- Plumbing connections
- Pressure washer frames
- Unloader valve assemblies
Using a dedicated unloader block allows the unloader valve to be mounted securely to the frame, helping improve durability and reduce vibration-related wear.
