    Sturdy build, but

    By Joshua on 12/03/2021

    "The Birch" has a good rep when it comes to manual pumps. So our branch decided to field test their battery operated version. We were looking for a back pack that can take a beating and survive the Texas heat. Pros: Its well built, hard plastics, good straps, relatively fast charging battery, battery is protected via its location, fits perfect in our trucks. Cons: wand loosens and could use some plumbers tape, no visual gage on how much product you have in the tank(you have to just feel for it), spray pressure is lacking and not as powerful as the Flowzones, and cone spray pattern only. Field testing still in progress...

    Disappointed with the Birch.

    Verified Purchase

    Had a few techs use the Birch, as well as myself. We all agree this back pack does not live up to the reputation Birchmeier had with the pump action. Battery will not last the whole day. The pressure is lacking compared to the flowzone. The wand comes loose constantly, even with plumbers tape applied. The hose is not very flexible. The wand handle is not agronomical, if your doing continuous spraying your hand will cramp up. I'd recommend sticking with the Flowzone Typhoon.
