Chapin 20004 Made in USA 1 -Gallon Lawn and Garden Pump Pressured Sprayer, for Spraying Plants, Garden Watering, Weeds and Pests

The Chapin 20004 1-Gallon Sprayer is well-built, simple to pump, and sprays evenly. Perfect for lawn treatments and weed control. Made in the USA and works exactly as expected—great value!

I used this for weed killer because it’s so much better than those stupid weed killer bottles. This plus concentrate weed killer was 100 times easier and about same price as pre mixed weed killer and better on your back. Filled up to the gallon mark then poured 24oz of concentrate. Few quick pumps and i had enough to finish driveway, sidewalk and couple of flower gardens. The spray nozzle has adjustability for a nice wide spray. The wand length was good so I wasn’t bending over. Definitely recommend

This 1-gallon sprayer exceeded my expectations! It’s lightweight, easy to carry, and perfect for a variety of tasks like watering plants, spraying pesticides, or cleaning around the yard. The pump builds pressure quickly and smoothly, and the adjustable nozzle lets you switch between a fine mist and a strong stream with ease.The tank feels sturdy and well-made, and the trigger lock is a nice touch for longer spraying jobs. No leaks, no fuss – just a solid, dependable tool that gets the job done. For the price, the quality is excellent.

There's one model below this one for a few bucks cheaper and I had trouble finding a model better that seemed reasonably priced above this one, so I settled for this as my first ever sprayer. I had no issues putting it together like other reviewers did but I think there is a definite possibility that some units may not be 100% based on this is really an entry model and probably not made for constant use or years of service. Some of the plastic materials reflect that.My tasks were to spray pesticide and lawn/garden products but I've found it useful for more.* The wand feels cheapish like you'd expect on something disposable as you do when buying RTS (ready to spray) bottles.* The container on the other hand seems pretty durable and made from quality plastic. It really baffles me that people complained about leaving pressurized liquid in the container and it failed. If you leave it full in your hot shed or garage then that's really your fault since the instructions are pretty clear that you should always depressurize and it is highly recommended not to leave any solution in it.* The pump, the pump action, the container sealing, the handle locking and the handle to hold while using it are all integrated and so you have 1 fail point for all those tasks. I expect something to fail or break at some point and I could not find where to purchase a replacement for it for when it does. The handle can easily become unlocked so when you go to pick it up the handle pulls out. The locking mechanism seems to just be a friction tab or something that will wear away.* There is no pressure relief valve which many others stated and it is a feature you will want, especially if you are making several gallons during your treatments as each time need to open the container you must let all the pressure out by spraying the hose until the liquid or air stops. An empty container will still be pressurized so you have to blow the air out first then you unscrew the pump/seal. If it is still pressurized you are going to get sprayed in the face as the air/solution leaves the chamber.* The unit doesn't come with any accessories such as a spray shield which would be just an extra piece of plastic over the nozzle to keep your spray where you want it. For being such a critical part of what you likely want the sprayer to do, it should be included.* They tell you to oil the pump occasionally but don't give you any or really direct beyond that what to buy to do that with. I don't want oil contaminating solutions. There is no diagram for where to even put the oil. Why not silicone or similar lubricants?* I plan to use bleach for an outdoor application and even maybe a monthly spray down of the showers/bathrooms but it is expressly incompatible with this unit. The problem is something to do with the seals in the pump reacting with bleach and so I have on order the bleach specific model. It's a confusing mess to figure out if you simply bought the bleach one will it also serve all your other needs or not so now I'm going to have 2 of these things to store and deal with. Why you simply can't purchase the bleach pump and swap it out for the standard pump based on your application seems like this company wants to bleed you slowly.* Extra things I've used it for are simple plant waterings so I don't have lug my 100' hose over the hard to reach shrubs. Fill a gallon of water and walk over and you get a perfect mobile watering station. Also some of these house plants like being misted and you can get a good fine mist while sparing your carpel tunnel. Toss a little Miracle Grow in the tank and fertilizing is better sprayed in than poured in.In all, this is handy and will be durable enough. It is missing features and the lack of replacement parts or interfunctionality with other products makes think I may have been better off with another brand or paying way up for the more expensive models. There's just something wrong with a product that is easier and cheaper to replace than to fix.

They work perfectly, and got two! Well made, nice pressure build up, even spray.

Definitely was a huge help with many applications. I had bought bug spray with a sprayer attached and it failed multiple times in attempts to purchase various ones. Plus I make my own natural fertilizer for my gardens and this product works great! This is my second time around buying it for various purposes. Spray nozzle has adjustable flow; which is also great. Definitely worth the investment in owning one or I highly recommend buying the 2 pack. I’ve also seen a recipe for deer deterrent by mixing1 tablespoon of baking powder1 egg yolk1 litre of waterblend gently, put in sprayer, spray all plants every 2-3 weeks (regardless of rainfall), or when thoughts of deer come to mind ..you'll be so happy …Definitely has kept the creatures from eating my vegetable plants and other plants on my property.Definitely happy with this purchase.First time around I bought 1 to test. 2nd purchase was for the 2 pack. Now I have 3 bottles and glad I have all of them.

This is a great pump sprayer. I use it for spraying pet odor remover, which is mixed with water, on our artificial grass. It works really well. I like the size. Not too big so it isn’t heavy to carry around. You do need to pump it every couple of minutes to ensure a good continuous even level of spraying. I liked it so much I bought a second one to use with a scent we bought to use for spraying indoors.

This 1‑gallon sprayer gets the job done for watering, applying weed killer, or pest control around the garden. The pump pressurizes easily, but the seals can wear out with frequent use. The nozzle adjustment is basic—they could’ve added more spray options. Good value for light to medium yard work, but heavy-duty gardeners might want something more robust.
