Vrt100-190d Unloader 26GPM 2465PSI Yellow W/Dual B is a professional-grade pressure unloaders from GP rated at 2465 PSI and 26 GPM. In stock and ships same day from Sun Brite Supply in Gaithersburg, Maryland.
Product Overview
Unloader for GP systems.
The unloader valve controls what happens when you release the trigger gun. It diverts water flow back to the pump inlet (or to a bypass) so the pump is not dead-heading against a closed system. Without a working unloader, the pump builds pressure with nowhere for the water to go. That kills pumps fast.
A bad unloader also causes pressure spikes, surging, and difficulty pulling the trigger. If your pressure washer surges between high and low pressure, or if the trigger gun is hard to squeeze, the unloader needs attention.

Compatibility
Unloader valves must match your pump's PSI and GPM ratings. An undersized unloader cannot handle the flow. An oversized unloader will not regulate properly.
- Match the PSI rating to your pump's maximum PSI or lower
- Match the GPM rating to your pump's flow rate
- Match the inlet and outlet port sizes to your plumbing
- Some unloaders are pump-specific (built into the pump head). Others are external and inline.
If you are not sure which unloader fits your pump, call us with your pump model number. We will match the correct unloader.
Applications and Use Cases
- Pump protection by preventing dead-head conditions when the trigger is released
- Pressure adjustment to set your working pressure for different surfaces
- Replacing a failed unloader on a machine that is surging or spiking pressure
- Upgrading from a lower-rated unloader to match a pump upgrade
Installation and Maintenance Tips
Install the unloader on the pump discharge port, before the high-pressure hose. Use Teflon tape on all threaded connections.
To adjust operating pressure, turn the adjustment knob clockwise to increase pressure and counterclockwise to decrease. Make small adjustments and test with a pressure gauge. Do not exceed the pump's maximum rated pressure.
Common unloader problems and fixes:
- Pressure surging: Worn piston or seat inside the unloader. Replace the repair kit.
- Hard trigger pull: Unloader set too high or piston stuck. Adjust pressure down or rebuild.
- No pressure: Unloader stuck in bypass. Check for debris, rebuild, or replace.
- Pressure spikes: Bad spring or worn seat. Replace the spring and seat.
Frequently Asked Questions
Why is my pressure washer surging?
Surging is almost always an unloader problem. The unloader is not transitioning cleanly between bypass and working modes. Try adjusting the unloader first. If adjusting does not fix it, rebuild the unloader with a repair kit. Replace worn springs, pistons, and seats.
How do I set the right pressure on my unloader?
Start with the adjustment backed all the way out (lowest pressure). Squeeze the trigger gun and slowly turn the adjustment clockwise until you reach your target pressure. Use a pressure gauge at the gun to read the actual working pressure. Do not exceed your pump's rated PSI.
When should I replace vs rebuild my unloader?
If the unloader body is cracked, corroded, or the threads are damaged, replace the whole unit. If it is just surging or leaking internally, a rebuild kit with new seals, springs, and a piston usually fixes it for a fraction of the cost of a new unloader.

Before You Order: What to Check
Getting the right part the first time saves you a return trip and more downtime. Before you add this to your cart, check these things:
- Model number: Find the model and serial number on your equipment data plate. Write it down before you order.
- Port sizes and thread types: Measure your connections. A 3/8 inch fitting will not thread into a 1/4 inch port no matter how hard you try.
- Pressure and flow ratings: Make sure the replacement part is rated for your system's PSI and GPM. Under-rated parts fail fast.
- Old part comparison: If possible, remove the old part and compare it side by side with the product photos and specs listed here.
- Still not sure? Call us before you order. We would rather spend 5 minutes on the phone confirming fitment than process a return because the wrong part showed up.
