Chapin G390 Hose End Sprayer for Water Soluble Materials, 20 Gallon, 32 Ounce Tank, Finger Control and Backflow Prevention, for Spraying Lawns, Weeds, Insects, Fertilizers, Translucent White

The sprayer is absolutely amazing and so easy to use! I used it for my natural soil amender and it just took minutes to get all of my front yard! No leaking, it was light weight and super easy to put on!

Just what i wanted - able to spray a tree..

Spraying ability: Has a good spraying ability and is easy to use, no leaks and good price. My issue after first use is that it didn’t appear to use any of the fertilizer concentrate that I had in the reservoir. Could have been a user error so I will withhold any sort of negative review until I use it again. It does work very well, trigger is easy to use and it sprays nice and evenly.

We have a guy who comes out to check on our HVAC twice a year - May for AC, September for furnace. For the last two years he has told me I needed to clean my evaporator coil fins. I knew enough not to use a pressure washer but was still doing it wrong. This year he said it was bad enough I needed coil cleaner. He said I could buy foam in a can but added "Ours comes in a gallon jug that we put into a sprayer." He was trying to point me to the right stuff while not endangering his job. His company would have charged me $600 to clean my unit. I searched for the can foam and this came up too along with the Simple Green Foaming Coil Cleaner. Bingo! Application is super easy. Put the cleaner in the sprayer bottle, attach to your hose. The first pass was both amazing and disgusting. Globs of dirt coming off my coil fins. I was shocked at how much better this was than my previous attempts with just "thumb on the hose". I ended up doing the worst side 3 times and the second worst twice. I used 1/4 of the gallon to do that. You will notice a change in how much foam is produced that indicates when you have run out of cleaner and are just spraying water. Attach the sprayer to the hose first then unscrew the bottle to fill it. The hose connector does not rotate so you want to attach it empty because you are going to be rotating the entire unit. The coil cleaner is very slippery so be careful about spilling on the sides. The sprayer tip is designed to let you get between the slats. Part of what made my previous attempts fail was that the protective slats for the unit protected too well. This solves that. You get under the slats and just blast crud off your coil fins. If there was a smell, I dont remember it so it must not have been strong. The value is through the roof. $30 for the foam and $7 for the sprayer. I should get 4 cleanings out of that. Call it $6 a cleaning vs $600.

I rarely leave negative reviews, but this product deserves it. The overall design of the Chapin 20-gallon lawn sprayer is frustrating and unsafe. The bottle does not stay securely twisted on, no matter how carefully it’s attached. During a single use, the bottle fell off five separate times, each time spilling chemicals all over me. Not only did this damage my clothes, but it also got directly on my skin, creating a serious health risk — all because the twist-lock system fails to stay sealed under basic use. The plastic construction feels cheap and flimsy, and clearly wasn't built for repeated use with real-world yard applications. For something designed to hold and spray hazardous lawn chemicals, you'd expect a higher standard of safety and quality. Extremely disappointed — I would not trust this sprayer for any application where safety or durability matters. Do not buy.

Well, it works and comes with clear instructions for use. However, the screw-on cap is a problem. First, the threads on the bottle and cap are molded too shallow so that they don’t engage very well. Second, the screw-on cap and the bottle have less than a full thread, meaning that when you screw on the cap, it barely turns a full revolution. Result: the cap comes off very easily, it fact it will literally pop off the bottle when it’s bumped during use (especially a full one bottle). Causing the bottle to fall off and spill the solution you’re spraying. If you try to tighten the cap, the shallow threads allow the cap to just pop off instead of tightening securely. This situation doesn’t make the sprayer useless, it just requires some care in assembly and handling/use.

The Chapin hose end sprayer is a must have. Actually I spray my yard with Dawn dish detergent it kills fleas, ticks and more. My dog hasn't needed any treatment for them in years. I spray it every year.

Small but effective.
