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 4.1 out of 5 by 122.

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.

I bought this sprayer about 3 years ago and it worked well...I find it much better to use than the hand-held type of sprayer. What I don't like is that the diaphragm pump went bad and the replacement pump cost $68 +$7 in shipping. Note that the only place I found to buy the part was directly from RL Flow Master, who is actually the manufacturer (not Echo). I've not been able to find the part anywhere else. What's "funny" is that I went to Home Depot looking for a replacement pump (which they don't have) and the box for the Echo MS-401 says "Lifetime Warranty" for consumer use. When I spoke with RL Flow Master, they indicated that the warranty does not cover seals and gaskets, which of course means that the diaphragm/pump assembly is not covered. So, buy a new one for under $100 or spend around $75 for the pump. I think I'm going to find a unit that has a pump that can be rebuilt at a reasonable cost.

Bought this because the reviews seemed pretty good over the Solo 4 gallon diaphragm sprayer which I've owned before. The Echo weirdly has a right hand pump right hand spray wand. Makes it awkward and more time consuming. I spray a lot!! Would choose the Solo over this next time I need a new spray

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

I became clogged and would not spray after 2 hours of spraying the first time. I expected a good product since it is made by Echo and that it should not become inoperable after only 2 hours of spraying.

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.
