Can I use a bleach solution in this sprayer?

How much does it weigh?

Asked by: Pops
I'd just guess that it weighs 10 pounds empty. Fill it with four gallons of water, and it weighs a lot more, of course, but the backpack straps and waist strap fit comfortably. This is a perfect sprayer!

How many gallons

Asked by: Dmoorie
Four gallon max capacity, and the indentations on the side of the tank make mixing small batches really easy--one side is marked in gallons, the other side in liters. This is a fantastic sprayer!

Does it come built

Example: I have looked at the manual and can't figure out what I did wrong.
Asked by: Alex
Yes, almost...you'll attach the pump arm on whichever side you like best--I put mine on so I can pump with my right arm. The bolt and nut is included. Then you'll put the wand onto the spray gun and attach a tip--I used the adjustable tip. It takes about five minutes to put together and be ready to go.

Multi-Use Back Pack Sprayer is rated 4.2 out of 5 by 14.
Rated 5 out of 5 by from This really puts out a lot of pressure when fully loaded. This 3 gallon back pack multi purpose ... This really puts out a lot of pressure when fully loaded. This 3 gallon back pack multi purpose sprayer will cover a large area without refilling. First of all, when I went backpacking in Europe 40 years ago, I got the first "Brand Name" Backpack that had the waist brand, my friends did not and mine was so easy to carry. I did not have the weight of 4 gallons of liquid. This backpack sprayer has the waist band that relieves most of the weight. Thank me later. It came with a few different nozzles, depending on what I am doing will see. I put it together very easily, only needed pliers to loosen the nozzle, the rest was a snap. Many benefits to this model, it comes with a pressure regulator so you don't over shoot, a the pump arm folds away for storage, the internal agitator mixes the batch so there will be no settleing of mix, I have a large lawn and gardens so this will end having to refill.

I just finished spraying 2 gallons of Roundup with this sprayer and thought it would be good time to write a review. Wearing this backpack sprayer reminded me of my backpacking days on the Appalachian Trail. The frame is really fairly comfortable, but just remember that if you fill it to its 4 gallon capacity, you are going to be carrying 32 pounds of liquid plus a 12 pound frame. I think 2 gallons is going to be my limit. The sprayer has a lot of great features: left or right hand pump operation, easy to pump, screen that fits in the top of the sprayer to strain trash, graduations on the tank to show capacity, handle on the top of the frame for storage and easy carrying. A couple of possible improvements: include an inexpensive 13 mm wrench to attach the handle - I have plenty of SAE wrenches, but very few metric. Also, a method to see how much product is remaining in the tank - without taking off the tank - would be very helpful. You can sorta judge by weight, but some sort of gauge would be helpful.

This Roundup multi-use backpack sprayer is reasonably comfortable and the design, quality and no leak down your back sprayer make it very easy to use. I highlighted the measurement levels so I wouldn't have to use glasses to fill the tank. The fold away pump handle can be reversed for left or right handed use.and offers different positions that made it easy to use in a garden cart. It got too heavy for me to carry when I filled it to the 4 gallon mark. Any thing over 2 1/2 gallons is probably OK for you younger guys. An extra long hose and the 21 in. poly wand allows you to reach either side of the tank easily. Comes with 4 different spray nozzles that are easy to swap out.

So you are a DYI type of person and you need to kill weeds, you can mix up your own weed killing poison then this is the back pack sprayer that you can use to get the job done. To build pressure just pump the handle that is at your side and you are ready to spray, like a professional. The unit fits on your back like your leaf blower so no holding the spray bottle in one hand and the sprayer in the other. The spray gun has enough hose to enable you to reach the areas that you need to reach without breaking the connection! the pressure is great and can be used to water or distribute fertilizer to you plants. This works perfect to spray repellent for you flowers and leaves. The container is also very easy to keep clean!

I recently got the Roundup Multi-Purpose Back Pack Sprayer to use on our property. For years I have used the standard 2 gallon cans that spray sometimes and sometimes spit out whatever product you use. The old can method is rough on the shoulder, especially after a few hundred pumps to get product to come out. This back pack unit is easy to prime and can be charged while you wear it. It is not the lightest pump as it weighs a bit over 12 lbs. and you add 20+ pounds of liquid and you have a load on your back. Fortunately it fits comfortably and has good spray patterns that reduce the need for constant pressure pumping. Because of the design and flow it makes short work of the yard. It is definitely a time saver and is well engineered.

If you can manage the weight you'll have enough product for a very large area of spraying and you won't have to be constantly mixing/refilling. Everything works well and I haven't had any leaks yet. The fold-away pump handle also accommodates persons who are right or left handed. There are a variety of spray nozzles to choose from depending on your application. When this thing is pressurized it'll shoot liquid quite a distance. That's very handy in my are because there are some very inaccessible, rocky slopes that are near impossible to walk on. I also appreciate the carry handle and the fact that it's easy to pump up the pressure while wearing this backpack. The filter screen is also a good idea. After using it was pretty easy to clean, too.

I usually use the 1 gal or 2 gal sprayer and decided to try this multiuse back pack sprayer so that I didn't have to refill quite as often. This one works wonders for that, with the large tank, I don't have to refill at all. it was easy to put together and very easy to use. It comes with several different nozzles depending on the spray pattern your looking for. It also has a pressure regulator to help keep the pressure at a constant rate. Its a great feature. It has a fold away pump handle that can be used for a right or left handed person. It claims to have a no leak pump design so that chemicals will no leak on your back. I have had no leakage as yet. It weighs about 12 pounds empty so having it rest on your back when you have a lot of liquid helps keep the weight distributed so you don't fatigue. This has really saved me time in the yard. This is really a great product.
