When one wears out, the machine stops holding steady pressure at the gun, which is why it is a common replacement part on pressure washer skids and pump systems.\u003c\/p\u003e\u003cp\u003eThe VRT3-310 is a black spring unloader rated to 4,500 PSI. Check that its pressure and flow ratings match your pump before you fit it. For several guns on one pump, use the VRT100 multi-gun unloader instead.\u003c\/p\u003e\n\u003cp\u003eRunning several guns on one pump?
