Been using this almost 9 years - still works perfect
Style: 4 Gallon, Euro Style
Well, I recently bought an electric backpack sprayer, because I wanted to try something new without the need of manually pumping my old sprayer, which is this sprayer. While I love my new electric sprayer, I am still totally impressed with this older one. The straps on my old one were nearly worn through, so I also bought a new replacement strap for it (this sprayer), and that was a little difficult to find. If you look at the pictures with this review, you'll see my original strap and how it is now only shredded threads holding the top and bottom of each side. At first glance, you may think I am making a negative statement of some sort about these straps. On the contrary though, I couldn't be more impressed with them. I just filled this thing with 4 gallons of water last week and took off spraying with no issue. These straps are made with some sort of super strong material. My goodness they are almost 9 years old, and have been carrying countless loads of 33+ pounds over and over, year after year, and they are still holding up though they are shreds at this point. Regardless, my review of this sprayer is that this thing has been a workhorse since I bought it in 2015. I have used it every year to spray all the weeds around the yard and fence line around our home, which is 2.5 acres, as well as my Mother's home, which is nearly 4 acres. It works amazingly well. It does require pumping it pretty frequently to keep a good amount of pressure on it, but I have no complaints. It is what it is. I have never had to change any of the seals on it. Somehow I did manage to break the big seal that goes around the top filter, which goes in first before the cap. I did that somehow right after I got it. I took super glue, and glued the seal back together, and it still works perfectly to this day, with no leaks or loss of pressure. I don't even remember how I managed to break it, but somehow I did. Regardless, a little super glue and patience and it was as good as new. The most important thing I can say about this sprayer is this. When you get finished using it, every single time, rinse out the tank with water and empty it a couple of times, as in use your garden hose sprayer to get down in it and spray around the sides and top and bottom to get all of the chemicals out, then empty it (2-3 times). Then fill it with another 1/4 to 1/2 gallon of water, pump it up several times, and lock the trigger in the on position with the wand pointed down at the ground, or in my case, gravel. Obviously do this in an area where the spray won't kill anything you don't want to kill. Keep it in the locked position spraying until the pressure is gone, and then empty the remainder of water in the tank. This will just flush the wand out really well. The point is, rinse it out well after every use (including rinsing off the big seal around the top filter) and this thing will last forever. What normally causes seals to go bad in these types of sprayers, is when people leave chemicals in them for a period of time, even if it's overnight. The longevity of my sprayer speaks for itself; almost 9 years old and still going strong. I am really digging my new electric one though. Still, I'll not be getting rid of this one anytime soon as it has proven itself to be extremely reliable year after year. I'd say this one will still be going strong long after my electric sprayer's extended warranty runs out and the battery goes kaput. The weed killer that I have been using with this sprayer, which is the best weed killer that I have ever found, is right here on Amazon called "Compare-N-Save 75324 Herbicide". It is far cheaper than name brand weed killers, and it kills everything. I mix 2-3 oz per gallon of water, and it kills everything. Weeds...poison ivy....everything (not trees though). It takes 7-10 days after you spray to see the results, but then it turns brown....because it's dead. Well, it kills everything except Yucca plants. Nothing kills Yucca plants. They come from another dimension or something and have root systems that go down 200 feet and spread out for a mile in every direction. Other than those though, everything else stands no chance with that stuff. This sprayer is definitely worth the money, and if you take care of it, you can pass it on to your great grandchildren. I did make a modification to this one. I took Gorilla tape and taped the hose around the right side of the tank, so that the hose is always there and doesn't get caught on anything. I didn't like it flopping around all loosey goosey. That's the only modification I made though. In fact I have had to change the Gorilla tape a few times over the years, as it wore out before the sprayer ever has. ... show more

Really good value - works a treat!
Style: 4 Gallon, Euro Style
A robust, well made and well designed home or semi-pro sprayer. Assembly was fast and easy; I was spraying within a few minutes of un-boxing the unit. The Chapin 61500 is super easy to fill and use. I am thus far pleased with the performance of the sprayer; it provides excellent pressure and good coverage. The pump mechanism is smooth and sturdy. This sprayer does exactly what it claims to do and will save you time, multiple refills and potential back pain when a large area requires spraying (verses a smaller hand-held unit). At right around 50 bucks at the time of this review, it is a bargain. Keep in mind that when full (4 gallons), this unit will weigh over 35 lbs. As such, I suggest filling it first, then placing it on an elevated surface (a deck hand-rail for example, which is close to the height of the tank bottom relative to your back when worn. Simply get one arm into one of the shoulder straps when elevated and then the other; snap the front cross strap together and you're ready to go. You can mix your solution by simply twisting your torso side-to-side once the tank is secured to your body. I also suggest freeing up the pump lever and the spray wand before you wear the tank so you can grab both easily once it is on your back. As others have mentioned, you will want to keep your left hand working the pump lever pretty much constantly as you spray to maintain pressure. After the first few minutes of operation, it will become completely intuitive - definitely the way to fly. I as well suggest when pumping that you raise your left shoulder as you push down on the handle to counterbalance the constant downward force on your left side. This simple maneuver will help you to avoid fatigue and possibly a sore shoulder or back. ... show more

Get the Old Model While You Can
Style: 4 Gallon, Euro Style
The thought of toxic chemicals dripping down my back didn't appeal to me. That's why the Chapin 61500 ProSeries Backpack Sprayer seemed to be the ticket. Even though it looked like a rinky-dink sprayer, both the pump and the spray valve originate at the top of the reservoir. Gravity wouldn't allow it to leak. Most of the Amazon Ratings rave about the sprayer. But, there's a twist. If you search for Chapin 61500 on Amazon, it will direct you to the new version. The new version has the pump and the spray valve on the bottom. I suppose that's why recent reviews complain about leaks. However, as of 3/17/23, they are still offering the old design. That's the one to select; not the "New Design". I do like the Chapin, but it's not without its faults. The unit has plastic grips for both the pump handle and the sprayer so they aren't flopping around when you're not using it. The sprayer grip holds it to the pump handle. Unfortunately, the grip holds onto the sprayer, but not the pump handle. I had to drill two small holes and ziptie the grip onto the pump handle; otherwise the grip would be sliding up and down the sprayer wand. The sprayer wouldn't shut off completely when I first used it. It would dribble out of the sprayer tip; a common problem with dirty valves. When I disassembled the valve, I found what appeared to be dried up lubricant around the valve stem. It must have been old stock A quick cleaning solved the problem. The sprayer worked well. It didn't require much pumping as another reviewer reported. It discharged a generous stream, so you may be going through product faster than usual. Even with the lightly padded, thin shoulder straps, the unit was comfortable on my back; even when full. You may have trouble getting the device on your back because of the weight. I placed it on top of my recycle bin before strapping myself in. Chapin had a good thing going with the old model; I wonder why they changed it. If you want a great leakless backpack sprayer, you better pick this old model up fast. ... show more

An unimaginable relief to have this
Style: 4 Gallon, Euro Style
I haven't actually used it yet, but I will within the next few weeks. I did assemble it, and having only used hand-held, top-pump sprayers before, this thing is a god-send; I will upload pictures on the updated review, so you can see it in more detail than what is provided on the Amazon site. But here's what I can tell you: THIS IS VERY, VERY WELL CONSTRUCTED. The pump action is very natural, and is a smooth rotation on the parts, instead of a harsh up-down impact action. The wand itself is extremely well manufactured, with a hose that I can't envision every kinking, wearing, becoming brittle, or otherwise breaking. The shoulder straps ARE padded, as advertised, and at least while it is empty, sit comfortably on my shoulders once adjusted - and there is a strap that goes around your waist/stomach to hold the tank in place while you pump. Adjusting the shoulder and waist straps is incredibly easy. So far the only issues I see that I'm going to have with it are: 1) it's going to be very heavy with 4 gallons in it, and therefore difficult to get from the ground to my back - I imagine I will have to have it on some surface (table, counter, etc) in order to get it on; and 2) the base which the unit sits upright on is going to gouge in to my back, very uncomfortably so. I am 6 feet tall exactly, and rather lanky; the bottom of the base, which has a ridge around it, sits on the bottom of my lumbar back an inch or two above my hips, and digs right in to the skin/muscles there. So, I'm going to have to either A) put some padding on it, B) put some padding on my back (I'm thinking my ribbed elastic back brace will work well for this purpose, which I might want to wear anyway), or C) both A and B. If you are 5'9" or shorter, I imagine there would be no digging in to the back, as it would sit comfortably on your butt. But given that using a 2-gallon hand-held sprayer caused my back to go out for 3 days every time I used it (and it took two fill ups to get my whole yard), I can only imagine that with this, I will actually be able to spray my entire yard and my back will be fine when I'm done. An unbelievable relief, as I have significant back problems (and a family that I like to spend time with, instead of laid up in bed). Once I use it, I will update this review and post some pictures. ... show more

Thompson's WaterSeal - A perfect sprayer
Style: 4 Gallon, Euro Style
I bought this to seal my fence using Thompson's WaterSeal. Before I start, I understand that Thompson's WaterSeal is a hot button topic on the Internet amongst people looking to protect their outdoor woodwork. I appreciate those opinions, but, for my purposes, I decided on Thompson's for my project, and if you have as well, this sprayer is nearly ideal. Thompson's recommends brushing, rolling, or spraying- but it is not recommended to use a high dollar paint sprayer. These pump-style chemical sprayers are the most-used option for spraying. I ran 20 gallons of Thompson's through this sprayer using the included fan tip, and it surpassed my expectations in ease of use and quick coverage. I sealed nearly 400 feet of 6-foot privacy fence, both sides, in about three hours. That was doing a thorough job, making sure to get all sides of the cross members and posts. I refilled the sprayer about six times as I didn't quite put in the capacity four gallons each time. As far as the spraying goes, this unit worked wonders. It does give your pump arm a bit of a workout, but I didn't find it excessively strenuous. Thompson's is a solvent based product, which concerned me as to how it might degrade the rubber o-rings, seals, and other components. I did spend nearly an hour after I sprayed cleaning the unit. I ran a gallon of clean mineral spirits through the sprayer making sure to slosh it around in the tank to dissolve all the residue. I followed that up with warm, soapy water run through the sprayer, at least one gallon. I then disassembled the sprayer and pump (it's relatively easy to disassemble and reassemble, and instructions are included) and washed all components in warm, soapy water, followed by a rinse. After reassembly I ran a good two gallons of clean water through the sprayer to get the remaining soap out. That brought my total project time up to four hours - a time bargain! Yes, the clean-up was time-consuming, but I was using the sprayer for a non-sanctioned purpose, and afterwards the sprayer is good as new. I look forward to using it again when that time comes, which, as Thompson's critics know, will be before I know it! ;) ... show more

Works well - for me, meters at 1.3 gal / 1000 ft sq
Style: 4 Gallon, Euro Style
Sprayer works really well - very happy with my purchase. Just some tips that may be helpful to some Tip#1 You'll need to understand the rate/area of spray. Rope or measure off a 10'X10' square on the driveway. Fill up the sprayer with water, and pump it up - spray the grass with water until you get all the air out of the system. Now time how long it takes to cover the 10X10. Take the sprayer over to a measuring cup and fill the cup or vessel over the same elapsed time it took you to cover the 10X10 area on the driveway - this is your coverage (oz per 100 ft). You can then multiply that by 10 to get 1000 foot coverage. My sprayer does 1.3 gal per 1000' sq, or .13 gal per 100' sq. This number is important when trying to figure out the mixing rate of various chemicals - they usually are oz per 1000' squared. Tip#2 If you live in a cold climate, you can easily winterize. Make sure the unit is empty - remove the cap on the bottom of the valve/trigger (dont lose the spring or the valve components - incidentally, this is also how you clean or fix a drip/leak on the nozzle - I've had debris get in the valve and flushing it clears the debris) Pressurize the sprayer to remove any water from the line, then add a good splash of RV anti-freeze (the red stuff - not the green stuff). Tilt the sprayer towards the pump side and pressurize the sprayer again until anti-freeze comes out the valve. Reassemble and bleed off the remaining anti-freeze through the wand. When turf season opens up again, just flush with some water and you're back in business. 3/28/2020 - I'm at it again, turf season is open, and the Chapin is right there with me. It works as good as new, and I'm just thrilled with this sprayer. No leaks, almost no maintenance (beyond winterizing). I'm betting this could be a 15-20 year sprayer. Heck, I'll probably be using the same sprayer when I arrive at the nursing home. ... show more

This sprayer is pretty darn big-- but exactly what I needed. No more refilling!!
Style: 4 Gallon, Euro Style
Very easy to assemble with simple hand tools-- such as your hands. It is bigger/heavier than you might think; ~35-40 lbs. full. Roughly a 12" x 24" footprint, 24" tall. (Not the greatest fit on most garage shelves, hence the four *s for Maneuverability) Nonetheless, once you've wrangled it onto your back it sits quite comfortably and is much easier than schputzing around a 2 gallon hand-held tank. Not very lefty-friendly, but any of the great apes should be able to figure out how to use this off-handed. This sprayer really works well. Just a few pumps (4-6 to start) and you can get up to a 15 ft. spray if you need it. (The bull thistle in the greenbelt HATES this thing-- just don't tell the HOA...) The pump arm easily controls the pressure, too. Efficient because you never have to stop-and-pump that puny 2-gallon junker 20 times. Everything is heavy plastic except the frame and pump handle. I'd suggest keeping away the dirt/grit (inside and out), wash it out thoroughly after each use, and apply a tiny bit of light grease to the moving parts, pump piston, and threads every 3-5 uses. (SuperLube O-ring works great.) I expect a good 15-20 yrs. out of this sprayer with typically 1-2x monthly use (bugs, weeds, neighbor's cat, etc.). Thus endeth the sermon... ;-) ... show more

Decent Prototype; Needs Iteration
Style: 4 Gallon, Euro Style
It technically works, and to that point it is slightly more convenient than pulling a bathtub behind you. 1) The clasps do not grip well, giving the tubes a tendency to decouple and rotate behind you. You will regularly have to remove the apparatus, reclasp the tubes, and then go through the ordeal of hoisting it all on your back again. 2) The instruction booklet is terribly written and missing useful information (like swapping spray mechanisms). 3) The straps were assembled backwards and twisted about a dozen times each, as if intentionally so by a disgruntled factory worker (whose name I did not curse, but only for the simple reason that I do not know it). 4) Water is absurdly heavy. I'm not necessarily blaming Chapin for that (though I'm not not either), it's just worth noting if you hadn't previously considered it. ... show more
