So far so good.
Size: 1-Gallon
So far the rubber is holding up. No leaks. The pump works well and is easy to pump. The spray is strong and steady. With just the turn of the top of the sprayer hose you can easily change the stream from a thin line to a wider spray area. It's large enough to be able to spray a very large area before running out but not so large that it's heavy and exhausting to carry around.

I love this sprayer!
Size: 1-Gallon
Who knew you could love a lawn sprayer so much? The size is great and can hold quite a bit if liquid. It's easy to use and sprays nicely. We used it to kill weeds that grow in our rocks which are impossible to pull without using spray. I would recommend for weeding but this can be used for so many different purposes. I also have one we put an all natural bug spray in to spray around our patio and it works great.

What a WONDERFUL Pump Sprayer!!!!! 😄👌
Size: 1-Gallon
The Chapin pump sprayer has quickly become one of my favorite gardening tools 😍. I use it to gently water delicate seedlings and to fertilize plants with a controlled application that avoids waste and overwatering. The adjustable spray nozzle is a great feature. The pressure works well, and the clear instructions and diagrams made setup easy. The handle makes it simple to pump and carry around, and the durable one-gallon translucent, chemical-resistant tank is easy to fill, with a funnel top opening that minimizes splashes. The ergonomic pump handle adds comfort with ease, making watering plants and grass effortless. I highly recommend this efficient pump sprayer for keeping your flowers 🌼🌹🌻, vegetables🍅🌽🥒, fruits 🍎🍋🍓 and seedlings🌱🌱🌱 well-nourished in your garden or private nursery.

Great little sprayer, but a pressure-release valve would help
Size: 1-Gallon
I bought the CHAPIN SureSpray 1-Gallon Pump mainly for using backyard chemicals, especially weed killer, and it has worked great for that purpose. It’s easy to pump up and holds pressure well, so I don’t find myself constantly having to stop and repressurize it while I’m working. The nozzle is another thing I really like. It adjusts easily from a more pinpoint spray when I want to target a specific weed to a broader spray pattern when I need to cover a larger area. I’ve also had no issues with leaking around the nozzle. My one real complaint is that I wish it had a pressure-release valve. When you’re finished using it and there’s still pressure in the tank, opening it up can be a bit of a task. You have to deal with the pressure before you can easily open it, and a simple release valve would make that process much easier. Overall, this has been a reliable little pump sprayer for the backyard. It holds pressure, pumps easily, the nozzle gives you good control over the spray pattern, and I haven’t experienced any leaking. Bottom line: A good, straightforward 1-gallon sprayer that does what I bought it to do. I’d just like to see a pressure-release valve added to make cleanup and storage easier.

Quality Has Gone Down Significantly
Size: 1-Gallon
bought the same CHAPIN sprayer about two years ago and was very satisfied with it, so I decided to purchase the same model again. Unfortunately, the quality of the new one is noticeably worse. The plastic feels much thinner than my older one, and some of the edges are surprisingly sharp and poorly finished. More importantly, the connection between the hose and the spray nozzle leaks water during use. It's disappointing to see such a big difference in quality compared with the same model I purchased two years ago. I expected the same quality as my previous CHAPIN sprayer, but this one feels cheaper and has a leaking connection right out of the box. so need to refund!

No more Incredible Hulk!!
Size: 1-Gallon
So I was informed by a handyman that I could use a sprayer and a mixture of concentrated bleach and water to get rid of the green stuff on the side of my home (cement siding), and eliminate the need for a pressure washer, which has no regard for the siding, and can actually damage it overtime. I opted to find a good rated sprayer on Amazon, and I was on my way. It arrived in good condition; no damage to any components. The directions were somewhat helpful, as I've never used one of these pump-action sprayers before. However, they were not streamlined. I spent more time looking at the 'manual' and guessing which one I ordered to make sure there were no missing components (wand extension, etc. etc.). =/ However, when I finished reading the instructions and assembling it, things got better. The opening for the container is wide and good for a spill-proof encounter. Also, there are markings on the side telling you how much of what you've used. Of course, I needed to make sure I was using the correct amount of all liquids suggested (total of 4 liters, which is equivalent to 1 gallon... 3.785). I went for a heavily stained surface (per the bleach instructions), and I'm glad I did. Key points I learned were the following: 1). When you're using the mist function, you don't have to pump as often (it tells you to pump until you can't anymore, essentially, but for me, average was between 12-15, depending on the amount of liquid remaining in the container. Less liquid=more pumps; up to 20+ at times). When I used the streaming function, I had to pump more frequently (obviously because more liquid was being discharged) 2). When you're releasing remaining pressure from the chamber after most of the fluid has been used, and it's time for a refill, do so ever so gently... that exhaust could get ALL over your beautiful face... or explode if not done appropriately! LOL! It's not a fizzle... it's a booming FFFFSSSZZZZHHH!!!! But it doesn't go upward if done right... it's going outward. Phew. =) As for the statement the handyman made, he was right! This stuff helped me get rid of ALL of the green stuff growing on the side of my home. I just followed the instructions provided, and I was truly pleased. Nothing like a neat house. Also, I have a one-story home, but the ceiling is arched, and definitely the height of a two-story home. This thing got the mixture ALL THE WAY to the highest point of my home!! No ladder or nothing?! YO!! I couldn't believe it!! I mean it truly blew me away! I set it on stream, of course. I did it just by rotating the nozzle clockwise (facing away from me, just like a regular handheld spray bottle), pumped the crap out of the container, making sure to never stand over the container while doing so, pressed the handle on the wand, and voila! No more Incredible Hulk!! I did follow up with a water hose and rinsed the siding... it's just so nice. As for the container, I added water and a little soap to flush the lines prior to storage as recommended, though I'm assuming they'll stand the test of time. I had an overall great experience with this container. Oh! And I'm glad I didn't need the extension wand. When I pull it out again, I'm sure it'll not disappoint. 5 Stars. Hoping this review helps you in making your purchase. I guess we all like it when things go right for a daggone change. (= Have a wonderful day! Z.

Perfect size

Nice sized sprayer. I've used it for grass/weed killer, mulch glue, pest defense and wood stain. Worked well with each product. Just clean well. Sprays evenly. No complaints.

First sprayer, very handy but lacks some functionality
Size: 1-Gallon
Aug 2025 update - I found a Chapin 2 gallon sprayer at Walmart for $15 that has a pressure reduction valve and comes with the standard spray head and a multi-function head that has 4 different spray types. The "shower" (like on a hose) spray has been very good. Being able to release the pressure before opening the tank is sorely missing from these models. The wand also has a bend in it, more like how a 'deck sprayer' does. I don't shop at Walmart often so you might check to see if they still have it. Also, not sure if I mentioned below, but this sprayer and the Bleach / Disinfectant sprayer are the same. The pumps are the same as told to me by Chapin. I bought both because I keep the Bleach one as a 'clean' sprayer with no pesticides. My 3 Chapin sprayers: 1 gal - this one, for pesticides and chemicals; insecticides and weed killers 1 gal - the bleach version, for house and siding cleaner that's bleach based (works great); for washing things down with soap and water 2 gal - from walmart; I'm using this for non pesticide garden and lawn products like fertilizers and pre-emergents. I'd recommend the walmart one over this one because the wand options and pressure reducing valve make it better. ---- 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.
