Solo 475-B-DELUXE 4-Gallon Backpack Sprayer

USA made, very good backpack sprayer,

Solo makes high quality products made in the USA. The one I just bought is replacing one that I have used for 25 years. Can`t ask for anything better than that.

I'm not a fan of this sprayer at all. It works, but that's where my love for it ends. when you pump it up, the pressure doesn't last long at all, you have to constantly pump the thing. the 15 dollar garden sprayer I had actually worked better, it just wore out my arm carrying it around. This thing holds a lot of liquid, but the shoulder harness is a major source of irritation. I have pretty broad shoulders and the straps keep walking off of my shoulders, putting all the pressure on the edges of the straps. After 1/2 hour of carrying this around, I'm actually sore. It's awful. ================ Edited @ 1yr exactly - lowered rating to 1 star I used this thing a total of 3 times. Just got it out this spring to use it and the module at the bottom of the tank leaked more than came out of the nozzle, soaking my back side and pants with weed killer. DON'T buy this POS

I have a large cattle farm and I have owned many backpack sprayers. Some good, some really bad. It was time for a new one and I was very unhappy with my last one, a SOLO piston sprayer. While the overall quality was OK, the amount of pumping for a piston sprayer is way too much for the spray you get. The diaphragm type sprayers I have had in the past have required way less pumping than the piston type. No more piston sprayers for me. Also I blew out several pistons/o-rings on the SOLO which shouldn't happen. I looked over the different manufacturers and saw a lot of very bad reviews due to leaks, hard to pump and overall failures. I bought this because the reviews were pretty good and it is a top of the line model. You have to be careful buying one because like this one, they come in lots of different quality levels but look pretty much the same. The quality on this is pretty good. Here are the pros and cons: Pros: Ratio of pumping to spraying is good. A few pumps and you spray for a while. Also depends on the tip you are using, the bigger the hole the more pumping you will do. Has lots of pressure. I can spray outbuildings with bug spray about 25 feet up. Not bad for this type of sprayer. They also have a high pressure kit you can get to replace the adjustable pressure valve in the tank. Nice sprayer, good quality, easy to use. The tips that come with it are good and of course it takes standard spray tips available at any lawn and garden place. Looks like it will be easy to service the pump and they list a pump rebuild kit for about 15 bucks. No leaks that I can find. My back finally stays dry !!!!! Cons: The shoulder straps are good and comfortable. The waist strap is a joke. Way too thin and the buckle is almost around the back where you cannot reach it easily. Looks like an afterthought. I replaced it with the waist strap from my old SOLO which was nice and heavy with a big buckle on the front. The pump handle was a little short for me, I am average build 5' 7" 185 lbs. You have to move your elbow back about 4" to grasp the handle for pumping. Not comfortable. I used a piece of metal tubing with a rubber bicycle grip and simply glued it over the end of their handle and extended it about 4-5". Now I can comfortably reach out for the pump handle and pump. After using it several times, I found the shoulder straps keep slipping off my shoulders due to the weight of the unit. I have added an upper strap across my chest to keep the straps together. Now it works fine. Belly strap keeps the weight over your hips not on your shoulders. It almost seems like they never had anyone really try this out for a week and give them feedback. So bottom line it is good unit. I would buy it again knowing full well what I would do to it when I get it to make it fit me. Quality is good, pump operates smoothly with acceptable ratio to spraying and good pressure. Parts are available and reasonably priced. When using it it feels natural and is easy to use. But be prepared to possibly make some changes to fit your body.

holds up to commercial use

Great item, glad for purchase.

It works good but don't waste your money on the Deluxe. The arm moves around when your trying to pump it up. It doesn't fold up like it supposed too. I will stick with the original. I use them for Chlorine (Power Washing) and they last about two seasons. I make sure I rinse them after every use to help the seals last. I go through several tips a season. The chlorine eats the tip opening up. The metal tips don't help either.

Works well. I have used Solo backpack sprayers for many years on the farm. A reason to buy Solo brand is being able to replace parts that do wear out. I bought a Tractor Supply 'some other brand' one time, and couldn't find exactly the parts needed to repair the unit (diaphragm, gaskets), so I had poor results and had to discard it. Solo puts more design efforts into ergonomics, too.

It takes me less than half the time to apply foliar feeds with the backpack sprayer. No leaking. High volume so infrequent refills.

I found it heavy on my back when it was full so attached it to a 2 Wheel Dolly and it worked very well.

Liked the back pack. Unfortunately the seat for the o ring seal, where the spray wand attaches to the trigger assembly had a small piece broken and leaks badly. would be happy with a replacement wand but this doesn't seem to be an option. I can buy a new one for about $50 but that's not going to happen, so I'm forced to return the whole unit...very disappointing and a waste of time and energy.

Does not have graduation indicators like previous unit purchased 15 years ago. THIS IS A MUST UNLESS MAKING FULL 4 GALLON MIXTURE.
