  1. What is the purpose of this? I read that the thermal relief valve is supposed to allow cooling water into the pump to prevent overheating while in bypass mode.

    I have a NorthStar 110 volt pressure washer. When using the pressure washer, a very slight drip, drip, drip comes out of the thermal relief valve. Is this normal? Is there supposed to be a tube plumbed up to it?

  2. I stored my Homelite UT80516 2200 psi Pressure Washer in my shed last Fall and when I took it out to use it this Spring the pressure was gone. I was all ready to order a new pump from Repair Clinic when someone told me to check the Thermal Relief Valve. Is there any way to tell if the current valve is faulty without ordering a new one? There is a bit of fast pulsing in the water but little more than tap pressure. Also it seems to burst a little pressure out when I squeeze the trigger and the engine revs vary a little when I release it.
    Any help would be appreciated…from anyone.
