Chapin 20000 1 Gallon Lawn and Garden Pump Sprayer

It is built from good high quality plastic material. The pump cylinder seal at the top is a thick O-ring that looks to be easily sourced should it ever need to be replaced. You must tighten the pump cylinder into the housing tightly to complete the seal. I own a backpack sprayer made by this same company, which has also impressed me over ten years ownership. At this point I am very happy with this small pump up sprayer too, it has a wand that is easily adjustable, sprays properly to the pattern i have adjusted it for. I don't see anything about this new sprayer that disappoints me in any way. I expect my tools and equipment to work properly, and this one does a great job indeed. I am glad i spent the extra few dollars to get this brand, it is great!

Love the sprayer. It pumps up well, holds pressure, sprays nicely, and doesn't leak. Not messy. I have been buying pre-diluted weed killer that has it's own integrated sprayer. Spraying on those products requires constant hand pumping, the spray pattern is small, and the weed killer dribbles and leaks. So, I bought concentrate and this 1-gal sprayer. I was able to cover a large area in 1/5th the time now. Wow. And, it was just so much a better experience. I highly recommend this product. BTW, the reason I selected this sprayer is that several other buyers had reviewed the sprayer and cautioned that removing the top when the bottle was still pumped up can cause liquid to surge up or the top to pop off. That warning persuaded me that this bottle could be pressurized more than others and would hold the pressure! I was right about my observation and very happy with my resulting experience.
