Questions & Answers

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

Asked by: salosenior
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 4.0 out of 5 by 132.
Rated 1 out of 5 by from DO NOT BUY!!! I am a professional pest control tech for Terminix. But, as any corporate job goes, they don't exactly give you top notch equipment to use. So, I took the plunge to invest in my own backpack sprayer. Echo is "supposed" to be a very good, dare I say, high end brand. Well, not this product. The MS-401 is absolute garbage. The pump only allows for EXTREMELY short strokes, if you can get it to work, so you end up doing 2" - 4" strokes CONSTANTLY!! The instructions are very extremely poor and says nothing about the strokes. Doesn't say that you can only push down a tiny bit. The amount of pressure coming out is disappointing. I'm honestly very disappointed and can't really believe "Echo" made such a piece of s&@t and really, makes me not want to buy anything else from Echo. Don't buy this product. You WILL be returning it.

It IS sold as an assembly for more than the sprayer sells for! Buy a SOLO 475 or buy a pro grade Echo. This one will work you harder keeping the pressure up and once the rubber diaphragm breaks down it's done. It's a high-priced disposable unit. New out of the box, the one I purchased did not have threads to hold the spring return cap on the spray wand handle. I found this out as soon as I pumped the sprayer for the very first use. It popped off and emptied some herbicide mix through the opening. I was a long way from the store and decided to epoxy it in place. Will not buy again and will not recommend.

Works fine sprays well, the arm from pump handle bolt heads rub the tank body, Gona have to replace bolts or it will eventually wear through. Also doesn’t pump in both directions only downward movements, unlike some backpack sprayer, my overall view is typical of echo “between homeowner / cheesy

Rated 1 out of 5 by from Fatal Design Flaws It doesn’t work as advertised so they stopped selling but won’t give refunds. Unlike other tank sprayers, you must constantly pump this one or it won’t spray.
