    I have about six different hand pump sprayers I use for chemical I use infrequently (Four backpack for primary chemicals). The problem I have most often if with the wand either with the nozzle clogging or on some units the nozzle will not spray high enough volume even when not clogged. All units have adjustable nozzles.

    The clogging problem could be solved if I could find a way to put a screen in the line like is used in some of the backpack wand assebmlies. Anyone have any ideas.

    I was wondering if I could just drill a larger hole in the brass tip to get higher flow. Anyone had similar complaints that they have fixed.

    Try using an old window screen to filter products and water when pooring into your sprayers, it works well. Just cut out a square piece and form it to fit into the opening of the sparyer.

    If you are talking about the canister sprayers the dirt and grass is already in the can when you pour in the liquid in. The funnel shaped mouth collects debris at all times, when you remove the plunger the debris falls in the can. I solved this problem by never using a canister sprayer again. Sorry, its a piss poor design. I suppose you could invert it and wash it before opening but if you had that kind of time you could rinse out a back pack and use it.

    I've found that anything with an open pumping mechanism is trouble. Meaning all hand helds that I know of are a problem. The pressure pump sucks up every grass seed, bit of grass and debris that it can find and puts it in the tank.

    Some back packs are a problem if they have a dished lid that stuff can settle in.

    I like Birchmeir back packs that have a remocvable jug that functions as the tank. They are the cleanest I've owned. Solo could be good as well.

    Me to bud. I went through 3 every time buying a more expensive one. I gave up and bought a lesco (solo) Backpack. With as much as I spent on the canisters I could of bought the Solo. Some times I'm so cheap it ends up costing me money.

    I agree that the open pump design stinks. I needed some pump ups because I use so many different chemical sprayers. I think it would be ok if I kept them tops covered when I wasn't using them. The worst problem is when the debris blows in while driving down the road. However, it there was a strainer or screen in the line, it would not be a problem. I just haven't found out where to purchase a strainer for the lines.

    Every problem listed in this thread boils down to dirt getting into the system. I use these pieces of junk too. But every single day you've got to empty, clean, & rinse these units entirely. Put them away only after they've performed well with straight water.
    Next time you go to use it, it will work.
    Pain in the butt, but that's all it takes.

    You can easily adapt a brass B&G handle to your sprayers. It has a screen integrated in the handle. As a matter of fact, you can put different sizes of mesh in there to handle different mixes like flowables or wettable powders. The key to keeping it in tip top operating condition is to backflush with clean water every day after use. Oh, and release the pressure when not needed.
