Hose Barb Outlet Advantage:

The hose barb outlet allows a discharge hose to be connected directly to the relief valve. This provides better control over discharged water and allows it to be routed away from the operator, electrical components, burner, and other areas where unwanted water could cause problems.

What it does:

The safety relief valve provides backup protection against excessive system pressure. If pressure rises beyond the valve's preset adjustment, the valve opens and diverts water through the hose barb outlet, relieving pressure within the high-pressure system.

Safety Relief Valve vs. Unloader:

A safety relief valve should not be used as a replacement for the pressure washer's unloader valve.

The unloader manages normal operating pressure and bypass operation. The safety relief valve serves as a secondary safety device if system pressure rises beyond the predetermined safe operating limit.

Why it matters:

Excessive system pressure can contribute to:

• Burst high-pressure hoses

• Damaged fittings and valves

• Pump damage

• Seal and packing failure

• Equipment downtime

• Unsafe operating conditions

The General Pump 100722 Safety Relief Valve with Hose Barb Outlet is an excellent choice for compatible pressure washer systems requiring a 1/2" MPT connection, up to 6 GPM, and an adjustable 1000–6000 PSI pressure range.
