    5 of 5 stars  Birchmeier Sprayer
    By Brier in Elmwood, WI on 08/25/2010

    4 gallons is just right for the larger jobs, yet not too heavy smaller jobs. Good to go all day on a tank or two. I've worked with Birchmeiers before and know how easy they are to repair and maintain if needed.

    2 of 5 stars  Straps and pump handle too short
    By Lance in Washington, Utah on 09/22/2012
    Verified Purchase

    When I received the Birchmeier Iris sprayer the quality looked great. When I put it on with the straps fully extended it fit to tight on my shoulders. If the straps where about two to three inches longer it may have fit. I'm not a heavy person just have wide shoulders. The other thing that needs attention is the pump handle was to short. Between the tight straps and the short handle it would have been very uncomfortable to use. They do make a Senior model which may have been larger?

    I was told by our pest control man that this was what he preferred and had used for years. I purchased one for some job sites I work on and am completely satisfied with this unit. The client was spending $500/month for a landscaper to do just the weeds. It will cost him a 1/5th of that now.

  • 3 of 5 stars  Not the best I've tried
    By Gary in Burton, MI on 11/08/2016

    The trigger assembly and flow control is great, but I did have to purchase gaskets for area that the wand attaches to the trigger within 3 weeks of use. Also the plastic nut at the same attachment point gets loose and leaks daily. Might want to use locktite but if the gasket goes bad again that might be a problem. Comfortability is less than many cheaper sprayers. I can barly reach 2nd floor peak on a calm day. Overall disappointed and will be going back to my previous brand.

Pump leaks , wand leaks, I called Domyownpestcontrol and the gaskets are ridiculous , i called Birchmeier and they said they would ship me some over a month ago which didn't come.

    By Chad in BESSEMER AL on 08/27/2015

    After using all other back packs sprayers over the years this is the best. It will not leak on your back like others will even if they say they will not. You can get all parts to fix it and easy to work on.

QHow far can a Birchmeier backpack sprayer spray? Looking to spray insecticide on my house.

ALike most backpack sprayers, the Birchmeier backpack sprayer can typically spray 10 to 15 feet.  There is one hand pump sprayer on the market that can reach up to 30 feet which we happen to carry called a slide pump sprayer.

QWhat is the most common tank size?
How large of a tank is most common with the pest control companies? Your professional opinion is appreciated. If the pesticide solution is mixed in the am, is it alright to keep it in the sprayer for an 8 - 10 hr work day? Will the solution have an effect on the sprayer if left in the tank too long?

AFour gallon tanks are common for backpack sprayers applied by professionals. We recommend discarding any mixed solution after 24hrs. It is also important to rinse your tank, wand and nozzle to prolong the life of your equipment.

QWhat is the difference between the standard cone nozzle and the other nozzles?
This will be my first backpack sprayer purchase. Going to start of using it for a couple of applications of bug juice and log wash for a log home. Then going to use it for general pesticides. Would the nozzle that came with it be acceptable? If there is another nozzle that may be better could you link to that please? Thanks.

A

When choosing a cone nozzle, it is dependent on the drop size you are wanting and what you are spraying. The adjustable cone nozzle that comes with the Birchmeier 4 Gallon Backpack Sprayer is a hollow cone nozzle. This nozzle gives you a wide cone spray with medium drop size. Please look at the two guides below to help chose the right nozzle for you. Please let us know if have any further questions.

QDoes the Birchmeier come with the fog to jet adjustable nozzle?

QIs the Birchmeier 4 Gallon (15k) Backpack Sprayer (109600001) capable of spraying concrete sealer?

A

No, standard Birchmeier sprayers such as the 4 Gallon (15K) Backpack Sprayer (109600001) should not be used to apply harsh chemical such as concrete sealer. Neither the seals nor the other components would hold up to these materials. We do sell other sprayers that can be used for concrete sealant, such as the Chapin Concrete Sprayer 3.5 Gallon (1949). The Chapin Concrete sprayer can be used for form oil and curing compound applications, but not for acetones. If you are only needing to spray a chemical like this one time, you could use an inexpensive sprayer such as the Chapin 1 Gallon Pump Sprayer†20000, and then discard the sprayer after use. (We encourage you to check with local waste disposal agencies for proper disposal.)†Please let us know if you have further questions.
