Chapin International60175 4 Gallon Backpack Sprayer for Bleach & Disinfecting, Made in The USA, 1-Pack, Translucent White

We have many large trees on our residential lot. Consequentially, we get a lot of black mildew on the clapboards/side of house. I had been using a pump sprayer to apply chlorline/water mix. I needed to use a long extension ladder to reach the top of the house, since the pump sprayer did not project very far. It was very cumbersome to use and repump up on the ladder and my balance isn't what it once was. I was looking for a sprayer I could run from the ground. This Chapin works very, very well for that purpose. It works best on your back, even when standing on the ground. It's just easier to manipulate the pump lever. Ihad to pump often because I needed to reach the 2nd story eaves. I would spray, let it sit for 5 minutes, grab the nearby hose and wash it off. The mildew poured off the side. No scrubbing necessary. When I was done (house is beige in color) it looked like the house had just been painted. I was ticked pink.To do a typical two story home took me about 5-6 tank refills (I was very meticulous). It was a pain to put the tank on my back, being small and older, but I didn't relish the idea of refilling it more often. Perhaps in time, I'll set it in a wagon and roll it around the house.Pros: fair compromise over a $25 home depot sprayer. Very simple to assemble, use, clean and store.Cons: If you are not strong, you may find it hard to put on your back.I'd reccommend this. Don't dis this if it's not the right application for you. It has it's limits and don't expect it to be something it's not. It's not a power washer.

The backpack worked great. It provided a stream of bleach that was about 25 feet. The unit is nicely made and the instructions were accurate. It pumps up easily. The only problem I have with it is the harness. The straps are very,very uncomfortable and really do not hold the backpack in place during the pumping process. The backpack slides down my back and tilts to the side during pumping. Since I used it to clean the front of my house, I simply put it on a ladder and used it from there rather than putting on my back. The unit did exactly what I wanted so I was happy. Redesigned straps would be a big plus and would be needed if you had to carry this on your back for any amount of time. Based on the construction and the parts available, I am expecting this unit to last for many years. Also, it arrived intact and on time.

I realized when buying this item that it was not made for what I wanted. But I could not find what I wanted so I just modified this and it was quite acceptable. I was cleaning my 30 year old cedar siding by spraying on bleach then pressure washing. I wanted a sprayer I could leave on the ground with a long hose and an extended wand that I could take up a ladder. So I strapped this sprayer to a small hand cart/truck and added about 12 feet to the hose. I also had a pressure washer wand set that attached to the wand lengthening it about 8 feet. It all worked pretty well except for the fact that I had to keep going to the unit to pump up the pressure. On your back it would be right there and most of the time But with the long hose and extended wand. I was mostly on the ground just a few feet away.

Good arm exercise. This sprayer doesn't work by pressurizing the whole five-gallon container. It pressurizes a chamber that then powers the spray. You only get a full-pressure burst for about 4 seconds before you have to pump some more. It will spray for several more seconds at lower pressure without additional pumping.It's too heavy for me when filled to its five-gallon capacity. Two gallons (plus cleaner) is about the max for me. But two gallons goes a pretty long way.I'm not sure why the manufacturer doesn't make all their sprayers resistant to bleach. I guess the idea is to give buyers the option to save a few dollars, or to give the company the option to charge a little more for a bleach-resistant one. In any case, if you plan to spray bleach solution, choosing a bleach resistant sprayer is a good idea.There was a little chemical odor from the sprayer when I first unpacked it. I think it was from the sprayer hose. I left it outside for a couple of days and it seems to have dissipated.It does reach the eave of a two-story house, but doesn't as easily reach the highest parts of the gable end. You might need a ladder for that.Assembly was pretty easy. It also comes with a fan spray nozzle.

omg, this is the biggest piece of crap I've ever purchased. I don't even know where to start.lets start with the pressure arm.. it pops out of the tank due to the poor design and plastic parts, you tighten down the nut and it just pops out again when you push the handle down. if you leave the cap loose it works but chemical and water get all over you. the thing is so poorly designed its like wearing a bed of nails on your back, thats if you can get the thing on. It is so uncomfortable to wear and the handle just flops around because it won't stay in the holder.. i could go on.... this thing is just poorly designed and made from end to end. Well, i can say the sprayer itself works pretty good but if you need a new one......... prepare to be taken to the cleaners on cost.. Chapin got me on this one..... never again

This backpack sprayer is constructed very well. The parts and hose are high quality. I used it with 30 Seconds Cleaner on my roof. I was able to adjust the nozzle as needed to spray another 10 feet up from an A-frame ladder. If you need to spray any further than that, you will need to make other plans. Pumping the sprayer is also a breeze. It took me about 5 - 10 minutes to get used to the operation of the unit and it was smooth sailing from there. If you follow the directions for taking care of it, I can see it lasting for many years. I also like the fact that they sell replacement parts if parts wear out.

One of the factory installed bolts at the bottom leaked and we didnt notice until I had leaked bleached down the back of a pair of pants and ruined them. Other than that it does what it says it will
