Chapin 20000 Made in USA 1 -Gallon Lawn and Garden Pump Pressured Sprayer, for Spraying Plants, Garden Watering, Weeds and Pests, Polypropylene, Translucent White

I had an electric version of this from different manufacturer, but that seems clogged all the time -- I was upset and decided to go back to basic pump action. I was right!! This works great, never had any issue. I used one bottle for insecticide/weed-b-gon, and the other for soapy water. I use soapy water to clean windows + kill bugs on contact.These are very simple bottle which works great, never fails.

For years I've been spraying my garden vegetable plants with hand spritzers. I apply water-diluted sulfur to my squash and melon leaves so they stay green and fresh, and water-diluted fertilizer to my tomato leaves. I need to spray both the tops and bottoms of leaves, but haven't been able to. I kept encountering the same problems with hand spritzers: spritzers that stop working all too soon; spritzers that will spray on tops of leaves, but not under leaves because they don't work when the nozzle is pointing upward; spritzers that can't fit in where I need to spray, so I can't get to the center of the plants; and spritzers that can't hold enough liquid to spray. I finally gave up and bought one of these. Before buying I could see I would be spraying with a wand, and that turned out to be ideal! I can spray in any direction (down or up) and I can reach in where I could not reach before. I'm not going back to hand spritzers!The included assembly instructions seemed confusing because they are for a number of different models, which made it difficult to figure out what I was supposed to do with this specific 1-gallon product. Turns out assembly and use are easy if you follow these steps:1) Rinse out the jug. It may contain dust and bits left over from the manufacturing process.2) Insert the filter-end (perforated cylinder end) of the white plastic tube. This will go to the bottom of the interior of the jug.3) Secure the white plastic tube you just inserted, on the outside of the jug, with the threaded-fastener that's captive and sliding on the outer hose, put there for this purpose. You're making a water-tight seal, so make sure everything is first seated right, then twist the fastener snugly in place.4) Attach the wand on the other end of the hose. You are again using a threaded-fastener that is sliding on the hose, and you are again making sure everything is first seated well before twisting snugly in place.That's it for the permanent assembly! For first-time use and to get a feel for how things work, fill the jug about 1/3 to 1/2 full with plain water. Drop the black pump into the top of the jug, with its handle on the outside. The handle is used to screw the pump into the jug so make sure the handle is down, into, and engaged in the top of the pump. Screw the pump in tightly since this has to be air-tight. Then unscrew the handle just a little, until it is loose and can be lifted up. Pump that handle to increase the pressure in the jug, and do it for longer than you might think necessary. Listen for leaking air where the pump is screwed in, and re-engage the handle into the pump to tighten it more if necessary.You want a lot of air in the jug so you can pressurize it for a lot of spraying. If you fill the jug too high there may be too little air to pressurize, and you won't be able to spray that much since not a lot will come out. You'll have to interrupt with more pumping sessions to get the pressure back up along the way. There's no law against this, it's just inconvenient. Filling half way or less makes the whole setup lighter for use, too.The wand has a handle you can squeeze, like at the gas pump, to get the spray going. Twist the end of the wand to change the shape of the spray, as you would with a garden hose.When you are done spraying, re-engage the pump handle into the pump, unscrew the pump and see and hear the pressure get released at the top of the jug around the edge of the pump.OK, you've gone through your practice session. Let's spray for real! Add water that dilutes what you are going to spray (use markings along the side of the jug to see 1-liter, 2-liters, quart, half gallon levels) and add your ingredient(s) to the water. You can shake the jug after it has been sealed and pressurized, then spray to your heart's content!Done for the day? Empty the jug and start again with plain water, then spray to clean everything out. I use this plain-water spray to water plants that could use it. Why waste the water?I am happy with my purchase, which is not something I always say. Of greatest importance? I see the effect on my plants!. Reliably getting to the undersides of leaves, and deep into bushy plants, are now easy, and really make a difference. They will for you, too.

I buy these every season and they do last a full season sometimes two. I use them to spray weed killer and insect killer and they do a great job at that. No leaks, easy to assemble. Over time though the seal where you screw it down gets corrupted. I do wish they came with replacement seals as it would cause a lot less waste of tossing them, but they would last a few seasons.

What attracts me to this Chapin sprayer is its fully-round gasket. So many other models deliver a flat gasket that way too often dries up too soon, rendering the sprayer no longer usable. This Chapin sprayer with its rounded gasket pumps easily and holds good pressure with no leaks. Make sure you never store your pump while it is still under pressure, or for sure you will quickly flatten and ruin your gasket seal.Hey Chapin and gardeners, make note of how I am utilizing storage space by looping a few inches of the long-enough spray hose with a bit of duct tape, and then securing the hose at the bottom of the sprayer with an old bicycle inner tube, like a holster.I regularly use three different sprayers at home (roses, spiders, weeds) so utilizing storage space is essential, because sprayers with attached nozzles take up a lot of room.

I wanted different sprayers for different applications, for instance, this one is going to be used exclusively for RoundUp. I want a dedicated one, because, hey, RoundUp KILLS stuff, and I don't want to have to try and clean it out so well that no vestiges remain of the RoundUp.The only assembly required is to screw the wand hose to the nipple on the tank. Works great!

I have been using this sprayer for two seasons now. I have had no problems with its function and the pump is still working well. The chemicals I use are water-based and clean up is a breeze. Even if I have to disassemble the pump, it is quite easy and the clean out is simple. i have not had to regrease any seals, o-rings, or other parts.

I was so tried of spraying with a spray bottle and they often broke, leaked... So I tried this out and really love it so far. It is new and I have only used it once, so I can update over time. here is what I like:Easy to useEasy to pump for pressurePressure lasted a long time before needed to pimpGood quality materialsSpray was perfect!I hope it holds up over time!!

This is the third one I have purchased and it seems they last for a season as I looked back and the last one I bought was exactly one year ago. But to be fair, I can’t say for sure if it was ever over pumped or stored without the pressure being released. I know it was not rinsed out before storage, so that is definitely on me. Works great right out of the box.
