    How to connect VBM to under bench water bottle?

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hi CS
    I have a VBM super with a rotary pump.
    Looking to have a large water bottle under it to draw water from instead of the tank.
    I haven't plumbed it in previously and it is too far from the water/waste in the kitchen.
    What would I need to do it and any suggestions how?
    I'll also connect a bottle up for the waste, but that is easy as it has an outlet.

    Thanks in advance

    Flojet bottled Water Dispensing System | Talk Coffee or have a tech add a non return valve to the inlet. You will need to adjust pump bypass accordingly.

    Great thanks.
    In regards to the non-return valve - doesn't it have that already? Under the machine it has a brass connection that I can connect the hose to - is this what you mean?

    The brass connection will just probably be a fitting to allow the connection.

    The issue is that the rotary pumps aren't good at sucking, especially if there is air in the line. If the water source is lower than the pump then this will be the case.

    The non return valve will prevent water draining back down the feed hose under gravity.

    The flojet will provide a positive feed to the pump and solve the issue.

    Another solution is mount your water tank higher than the machine pump and have the tank feed water from the bottom of it. This way gravity will provide the initial feed to the pump and you shouldn't need anything as it will always have water available under slight pressure.

    You don't want to run your rotary pump when it's dry.

    Cheers

    thanks... I've noticed that the pump does struggle when air is in the line. I have had to turn the machine off and wait for it to "reset" and then turn on again after 5 mins. It then sucks water from the tank.

    ok, so do I need both the flojet and the non return valve?
    the water will be under the machine, as there is no option to put it above.

    This is pretty easy on the vbm - the manual says that I turn a lever (which is under the machine) 180 degrees to the left. That's it?

    No. I would say the lever you are referring to is to select tank or plumbed feed for the water supply.

    Chris was referring to adjusting the brew pressure. As you will be supplying pressurised water to the pump it will need adjusting.

    Cheers
