I love this Chapin Pro 4 gallon sprayer, it has been the best one that I have found. I have used a lot of sprayers,and this one has been the best by far!! Only thing I would like is the option to add an extension to the wand.
I live in coastal GA, which means an unrelenting assault by palmetto bugs (giant cockroaches for those fortunate enough not to know), sand gnats, and ants. Before buying this sprayer it took me 3-4 hours to lay down a barrier around the house, garage, and workshop as well as the interior of the garage and workshop (I forgot to mention the nasty spiders lurking in those places). My smaller sprayers have limited pressure, making it a real bother getting around the shrubbery. The frequent need to refill chewed up a lot of time as did that to set it down and pump it up. From start to finish I got the job done in a little over an hour with this sprayer. I had to refill only once, and the pump lever let me effortlessly maintain maximum pressure. The sprayer delivers a wide stream, even into the rafters. The only problem I had (and it is a minor one) was getting the thing on my back when filled. Next time I'll set it on a table first. The rig is surprisingly comfortable once the straps are adjusted - even with a bad back I barely noticed the weight. There is a right tool for every job. For my money, this is precisely that.
This Pro Series 4 gallon is a nice unit and it makes quick work of my needs when spraying my property as i use it for weed and grass killer. Saves me time from doing refill and the adjustable pressure is a nice feature. I don't think anyone could go wrong selecting this unit.The wand is easily adjustable and the hand pump is both very accessible and effective. There is great filtration to help keep junk from getting into the tank or wand and it's easy to clean when done. I've used it both full and with just only 2 gallons and have been delighted with the results from using the Chapin.
How far does the Chapin Slide Pump Sprayer reach? A second story home?
This backpack sprayer only reaches about 10 feet high. For higher areas we recommend the Chapin Slide Pump Sprayer which can reach up to 30 feet high. We also have a video that shows the slide pump sprayer in action on the slide pump product page.
Almost every sprayer i've had leaks or drips chemicals in my trailer. Makes cleaning out the trailer rather pointless. Will this one leak if I leave chemical sitting in it, and it sitting in my trailer?
You cannot store chemicals in sprayers as it will weaken the gaskets and other portions of the sprayers and cause leaking. Leaving chemicals in sprayers for more than 24 hours at a time will also void any and all warranties offered by the manufacturers. For short term use (for a few hours) stored product in the sprayer should not leak out as long as the sprayer is kept upright.
Hand held sprayers have the pump on the lid that you hold. If you notice in the picture there is a rod that extends from the bottom of the pack. On backpack sprayers since you where it on your back, the rod extends out from your side and you pump the rod up and down to pressurize the tank.
How far will the Chapin Pro Series 4 Gallon Backpack sprayer reach horizontal (craw space)?
Most hand pump sprayers including the Chapin Pro Backpack sprayer will only spray about 10 feet at the most from the end of the sprayer wand. If you need to reach further, we do sell the Chapin Slide Pump Sprayer which can reach up to 30 feet away.
