The Chapin 63900 backpack commercial duty sprayer is pretty awesome. probably the nicest feature is the dual displacement pump it integrates both diaphragm and piston technology into one and the design also helps eliminate leaking, that nasty feeling when you feel liquid running down your back and leg, the wrong kinda of liquid. Another incredible feature is the lid they put a handle on the lid making it simple to pick up and move. On this sprayer it also has padded shoulder harness as well as a padded back pad and a chest strap. It holds 4 gallons and it's hard for me to carry that much weight but 3 gallons is very tolerable, the padding works great. I love the pump handle too, install on left or right side allowing you to set it up so that you are comfortable and it folds up and away when you want, and when you set it, it will not unset itself. It is easy to pump up and it holds pressure much better than any backpack that I used previously. Meaning after I get it pumped up I can shoot a stream all the way up to the second floor eve of my home or create a very fine mist to cover the ground completely without rapid constant pumping. The control handle has a heavy duty everything and a stout trigger lock, with a filter inside before the stainless wand. The pump handle has a clip for the storage of the wand. The tank feels super thick and rigid with a big open mouth so a big hand can reach inside. Pumping creates blasts of liquid in the tank that keep the 3D filter clean. Then a big filter basket fits in the neck to keep big stuff out of the big opening, totaling 3 filters. The lid is easy to put on or take off one handed. The sprayer will sit up on it's own. I think this is durable, repairable and very capable and the sprayer most likely to not get you frustrated. It sprays great. Just the bullet nozzle has a wide range so while you work you can go from mist to long distance reach in seconds. Includes a wrench for the pump and an alternate spray tip. It's the sprayer to have.

I selected the 4 gallon backpack sprayer combo, for all the neat Features and the Advantages they give me. MY old sprayer [see photo] capacity is 1 gallon and the handle is also the pump. This new sprayer has a long list of helpful Features starting with the dual action pump that increase the psi so that I can spurt higher up my pecan tree. The next is the wide mouth that allows me to fill it without funnels or trying not to spill any chemicals. The next is the large basket filter is the first layer of filtration that cleans the fluid.. Next are the self cleaning jets that eliminate operational sprayer filling. Next the swing away pump handle can be left or right hand so today no one has to struggle using it. A back pad is next on the list and it cushions the back during prolonged uses. The stainless wand with a cushion grip had the 3rd. filter. and these Features give the added Advantages that Benefit me when I use this sprayer. May this help you make an informed decision to own a Chapin Backpack Sprayer.

This commercial duty sprayer by "CHAPIN" is exceptional. Over the years I have purchased, used, and then disposed of many outdoor chemical sprayers when they stopped working. They eventually failed even though I followed the owner's use and maintenance instructions carefully. Immediately upon un-boxing I recognized the high-quality and heavy duty construction of all the component parts. The sprayer is easily assembled per the well-written and illustrated "Use and Care Manual". I was very impressed by the fact there are clear instruction and illustration on how to fix/repair minor problems if they should occur. The sprayer will hold up to four gallons of liquid and comes with three spray nozzles (Brass/adjustable, Poly/adjustable, and Fan). It is my opinion that if you follow the "Use and Care Manual" this will be the last sprayer you will ever need to purchase. See attached photographs. This is the first backpack type sprayer I have ever used. So I did find the instructions and illustrations somewhat minimal on how to attach the unit to your back. It became a two person effort to get the sprayer onto my back and safely secured. Then I needed assistance in removing the unit from my back when the tank still contained liquid. It would also be nice to have a pressure relief value available instead of holding the valve handle in the "On" position until the pressure equalizes.

    I have owned the small Chapin sprayer for years. I thought I would try this backpack one thinking what a great way to water everything (hoses aren't practical here). Had to put the sprayer together, attaching the handle was weird/difficult. I returned this because of the way the handle is placed makes it VERY awkward to use and definitely not easy at all. I'm really disappointed that this didn't work for me because it's a great idea. The Chapin company is a local one and I love the smaller one, will have to buy that one again.
