Questions & Answers

This unit comes with four tips for sprayer. How do you change them?

Asked by: Daniel
In my bag of nozzle-tips the retaining nut was already attached to the nozzle body and nozzle cap assembly. Attach that nozzle tip (which has the retaining nut) to the spraying wand. Once it's attached you will be able to unscrew the nozzle cap from the retaining nut. Unless it's attached to the wand you won't be able to unscrew the nozzle cap. Hope this helped.

how far will the sprayer spray the fluid?

Asked by: Buddy
The sprayer will project four feet in front of you, the same with most pump sprayer that I have used. It is not made to treat tree tops I am very satisfied with mine.

I have narrowed my purchase between 2 ECHO products: the 4 gallon diaghragm sprayer and the 4 gallon piston sprayer. Can you explain the difference. t

piston sprayer. please explain the difference between the two
Asked by: peter
Diaghragm pumps can handle wettable powders and soluble packets better than a piston pump. Piston pumps have smoother action but are not as robust. So it really depends on the product you plan to use.

4 Gal. Diaphragm Backpack Sprayer is rated 3.9 out of 5 by 180.
Rated 5 out of 5 by from The good quality, durable sprayer, in new user friendly technology. The Echo Diaphragm technology sprayer is better than the conventional piston pump, since I do not have to unload it from my back to pump air. I can go all the way until the tank is empty; just keep on pumping air occasionally, while it is still on my back, when the pressure is down. It is a heavy duty sprayer, well made , with all durable materials, and easy to carry on the back. The Diaphragm-Pump Backpack Sprayer is designed for use with powders, liquids and water-soluble solutions., but not flammables, caustics or bleach. (do diligence) The pumping handle liver can be used for left- and right-handed application. I have tested the sprayer and I am very happy with its performance. The spray is powerful, no leaks anywhere and very easy to pump and pressurize when on back. Please see my video to see the spray in action and also the diaphragm technology at the bottom of the sprayer. Thanks Echo, for the good quality and durable sprayer in a new user friendly technology.

After unpacking the sprayer and taking it home to do some weed control, I filled the tank with herbicide and got set up to spray. I attached the spray wand to the hose and noticed there was no tip. When I looked at the owners diagram I notice the tips that were suppose to come with the sprayer. They were not in the box. Upon further investigation I noticed that the box containing the sprayer had been re-taped, (apparently a returned box or at least, a box that had been opened.) I did not return the sprayer because I had already filled it with herbicide. I am ashamed to say that I merely relented and just decided to buy an identical sprayer, making sure the box had it's original packing tape. Now I own two sprayers with one set of tips. The product itself works very well.

I’m 5’4” and 115 pounds, my husband is 6’2” and 215 pounds so it’s difficult to find product that will work for us both but this one does. We have a big yard so I filled the tank to the top and was still ok carrying it for the full job (about 2hrs). The nozzle options are great and simply explained on the blue paper instructions. The straps are comfortable and the pump is easy to use. We’ve done a few treatments and it’s working really well with no clogging. It’s easy to get back into the box for storage. Highly recommend.

Has worked perfectly, however developed some sort of leak in the tank at the end of last season. Manufacturer honored their warranty and helped me with a replacement. It was one of the main reasons I chose this specific backpack sprayer and I wanted one the was durable, but with a brand name and reputation to go along with it just in case... I have owned less expensive and less quality sprayers in the past and I'll just say, you kind of get what you pay for. I would recommend this product.

Rated 1 out of 5 by from Poor pump design This is a decently built sprayer but after the first use I found the pump stroke to be extremely short. After further investigation I found the diaphragm arm hits the plastic shroud that covers the diaphram. This requires lots of short strokes to pump the unit excessively to keep pressure. Of course this resulted in a worn out arm by the time I finished the first tank of spray application. After looking for the receipt which was gone months ago I opted to take my Dremel tool and cut away the plastic that was impeding the pump arm which made the unit more user friendly. After reading some of the posts here about "clicking" and "popping" during use I can only assume this is a design flaw rather than a one time incident. I have since relegated this unit to weed killer as I don't apply much of that and have purchased another brand for my heavier spraying jobs.

Only fault is there should be a chest strap. Pumping up and down with one arm, and moving the spray wand back and forth with the other arm, the sprayer straps slip off my shoulders. I use a bungee cord on the straps just above the pads to keep the sprayer in place. I have about 1 1/2 acres and long gravel driveway that requires weed abatement. So much easier than a pressure pump carry around bottle/jug sprayer.

This Echo sprayer has poor pressure for TONS of extra work (pumping) due to the diaphragm pump design. Each pump doesn’t increase that much pressure in the tank so you have to pump many more times per volume of spray compared.

This is the second one I have purchased because the first one became clogged and I needed to spray right away. Product is awesome, company has great customer service and warranty. I was able to repair the original one I bought and now have 2.
