    The question arises again. I'm looking for feedback on the Sump Buddy (municipal water "powered") as a backup or auxiliary pump for use in power failures (save me getting up every twenty minutes and literally BAILING for twenty minutes, all night!

    Windstorm and rainy season is on upon us.............. :eek:

  3. they are all junk

    dont trust them


    the water operated ones are pretty wimpy,



    water operated ones seem to wear out in
    the controll valve switch that is triggered
    when the water rises....

    no one ever gives them exercise,
    and you should turn them on at
    least once a month to give them exercise

    so when they stand dormant for a long time
    the switch seems to not work or the bottom of the
    controll that is in the water is totally clogged up with
    silt and wont "spin" and pump out the water....

    itis some sort of "venturi " type of fitting that sits down
    in the water with the water hose tied into it and when the
    water makes the fitting spin it pumps out the pit too....

    its prretty wimpy......

    I have put a few in and am not impressed




    BUT
    If you absolutely have to have anything
    but the best I suggest you at least set it up
    on a separate line going out of the house.....

    DO NOT tie itinto the regular sump line becsuse sometimes the
    head pressure is too great for it to overcome and
    actually pump water out of the house....depending on what
    is going on outside at the other end of the pipe......


    just put another pipe out the side of your house
    for the emergency back up pump


    look at this one, its the best

    I can't find any specs on the Sump Buddy but there is quite a bit on Basement Buddy. They seem to spec the water requirements based on only 5 ft of discharge head. At the water supply requirements shown it would cost about $5 per hour for water and sewer charges in my town. Sewer charges because we get charged for sewer based on amount of water used.

    The mechanism is not described but it looks like a venturi system and purports to remove 2 gallons of water for each gallon used at 5 ft of head. At 15 ft of head I would guess it will use about 1.5 gallons of water at 50 psi for each gallon removed.

    They don't mention backflow preventers but I can't imagine that any public water supplier would want that thing on their system without backflow prevention.

    It requires too much water for a well system.

    I would go for a battery backup.

    Bob , if it is like the ones I have seen it is basically
    just a "glorfiied ballcock" with a vaccuum breaker
    build in jsut like the old palstic ballcocks have.....


    it just sort of has a weight on the bottom of it
    hanging down into the pit full of water holding the valve in the off position.

    when the water rises the weight or " bouey" lifts
    up and trips the spring loaded switch and then the water starts
    rushing through the venturi
    fitting......

    Its almost like a flushing a toilet...upside down??? I guess?
    bacisally its about the smae principle.


    I have seen a couple that accidentially ran for a a few weeks

    because their is no alarm on most of them to tell you they are

    running up your water bill sky high.........


    but with the head and all, its just best to put it out on
    its own drain line stubbed out of the house a few yards
    into the grass....I suggest about a 1 inch or 1 1/4 pvc drain is all
