    we got a few of these 4 gal battery powered back-paks

    handy to have....when it operates correctly

    heres the problem, half of them do not operate corectly. All were purchased this spring.
    this is whats happening, turn on the on/off switch and the things begin spraying automaticly without using the wand lever to turn it on. This is not a huge problem because we only use these sprayers for mosquito control and some shrub insect control. It would be a problem if we used them for herbicides! But regardless what we use them for we would like them to operate properly.
    The other thing is that they continue to 'flow' even with the power switch off. Gravity siphons material out of the backpack, so we need to keep that wand up over our heads while walking and when storing them in the truck the wands need to be secured up higher than the backpack itself or we lose product.

    So, whats happening? What do we need to do to fix this?

    You know, we try out these new technologies to help make the job easier and to get things done quicker...but all they seem to do is cause more aggravation.

    that's diappointing to hear - that was/is going to be my backpack sprayer of choice for manual applications. What is a viable alternative - hand pump-free like the Shurflo?

    Dman, these Shurflos have 4 spray settings. I'm not sure of the output of these settings but you need to hit the on/off switch to increase output (on/off switch is located on the bottom of the backpack, so you got to reach your arm around yourself to get at it) In other words we have to hit the on/off 5 times. The first time is the lowest output, second time increases output, so on till the fifth time shuts it off.
    When we are using a mosquiro control or an insecticde for shrubs its not that big a deal to have to keep hiting the on/off till it finally shuts off. And the gravity siphoning is aggravating but not damaging to plants though a definate concern for operator safety.
    On the other hand, If we were using an herbicide....well you can see how this could be trouble?

    The wand has also been a disappointment. Again half of our units have wand issues. The spray tip comes loose where it connects to the aluminum (sp) wand. We have re-glued them...but that is only a temp. fix. Evidently we dont have the correct type of glue?

    The other thing I really dont like is that you need to recharge the batteries using AC current. Would be nice if DC were used, we could just recharge from the truck. Sure a converter in the truck converting its power to AC would be a solution. Just would be nice if Shurflo gave an option to charge AC or DC

    I bought one in June with no problems to date. Use it strictly for herbicides and given the considerable cost, it would be great if Shurflo would get a handle on their quality-control and/or design. I was apprehensive about buying it since the weight is quite a bit more than a conventional "walk and pump" but I was sold on the consistency of flow volume. I normally discard cheap hose attachments and use stainless worm clamps. The small Oetiker style clamps just won't stand up to daily use. TSM, I also got rid of the cheap aluminum wand and replaced with a brass one. The adjustable tip is ok for insect/disease app.s but I needed something I could put a flat-fan tip for a true band type spray pattern. A Tee-Jet 8004 works well.

    I returned my 2 - 3.5 times to the factory in Calif. for problems and they sent me new ones each time ,
    The redesigned the hose connection because of me .
    Just return then for new ones , no problem .

    TSM, I bought one this spring as well, I had no problems at all, nothing, its worked great. I dont like the different speeds, I think it would be best to just have a on/off . I only used it for mosquito control
