I've been buying Chapin sprayers for more than 3 decades. For both home and commercial use, and have been, with very few minor exceptions, quite pleased with their products. I bought this sprayer as a (upgraded) version of the many junky Round up models that rarely survive from season to season. I don't believe I had unreasonable expectations, but at twice the price, a good quality light sprayer, ya know? I ordered the 3 gallon model. The one I received was a match for the one pictured. It was a bit top heavy. The handle and trigger was small, really small(maybe 60% of the mentioned Roundup sprayer) The wand was very lite (once again, small diameter) and it wobbled. It assembled normally and I filled it with glyphosate. I pumped on it and it didn't spray. I pumped again and listened. Air was leaking profusely. I removed and recrewed the pressure valve, and tightened it up. Same result. I called Chapin and told them I had a bad valve. They were cool and sent me one a month later(ug). I unboxed it and went to install it and (ug), wrong valve, Needing to spray, I got a pvc plug and defeated it. I made a mental note to not over pressurize it. I pumped it up, nothing. I rechecked the pump and repeated the process. Same result. Being top heavy, the cannister fell over, and being old and slow, by the time I stood it upright, I had lost 1/3 gallon of spray. Emptying the spray into a bucket, I pumped it up a lot. On the side of the neck, right over the pressure valve, the pump neck is warped. I called Chapin for replacement parts. They sent them, 3 weeks later. Wrong parts. Another call, and they sent me a new sprayer. This time however, they took an under engineered product, and further under-engineered it more. The hole in the neck is now 70% of the size of the other one, making it not only top heavy but hard to fill(you have to set the sprayer in a 5 gallon bucket to keep it from falling over). The pick up tube is smaller. Okay, what the heck, spraying season is almost over, why not. So fill it I did. I put 3 gallons in it and went to town. Heh, new problem. When you twist the handle to lock it and start walking, the locking mechanism cant hold the weight...it won't support more that one gallon without falling out. So I'd walk a little, put the can down, spray, repeat. But it did hold pressure. By the time I had sprayed 2 gallons, the wobbling of the wand increased. Bad enough, but where the brass tube connects to the trigger mechanism started dripping, like a cup every quart. So I had grass killer dribbling all over when it shouldn't be. Yay! called Chapin again. This time, I got the woman I had gotten like my second call and she had no sense of humor. "What do you want us to do?", with a tone. I want a sprayer that works. I will box up all these parts and ship them to you at my cost. I'm not trying to take advantage of you After much accusational tone. She talked to her supervisor. "Were sending you a sprayer. Don't call us again. Don't call us again. Don't call us again." They have obviously changed manufacturing plants, deep in the heart of china. I really liked this company and have spent many hundreds on them. But I don't know about buying a product from them without holding it in my hand first, like we have to over the net. I would not, under any circumstances recommend this sprayer. I got my new (different model)sprayer in less than 2 weeks and am pleased.
