VRT 3 Unloader

VRT3 Unloader

What it is: A valve (unloader) used in pressure washers.

Purpose: When the spray gun trigger is closed, this valve diverts water flow back (bypass) so pressure doesn’t build up and damage pump.

Specifications:

Max Pressure: ~ 4500 PSI

Max Flow: ~ 8-10.5 GPM depending on variant

Inlet / Outlet Ports: 3/8″ female threads in many models

When to adjust / replace:

• If pressure doesn’t drop when trigger is released (meaning unloader isn’t diverting).

• If pump is noisy or feels overloaded.

• If leaks are visible around unloader.
