  • Re: Problem with Hydro II Pump

    This is my first post hear so first of all I would like to say Hi

    I have a hydro II pump on a spit fire
    The pump is not producing any pressure what so ever on the solution line or the gage
    The mixer tank is full and when you take the inlet hose off of the HP pump there is water flow going into the pump
    I have a hunch that it may be the way the inlet hose is plumbed up
    I have a manual but it's not rely enough detail
    Any suggestions on this one most appreciated

    Prime your Truckmount

    Please make sure that you suction prime the pump to remove any air bubbles from the pump head. This is done by installing a blank male QD on the end of your pressure hose and with the machine running, place in the end of the pressure hose in your vacuum hose and close off you escaping air around the pressure hose. If this does not work, change the pressure regulator on the machine. If this does not work you will have to decide if you want to replace or rebuild your water pump.
