VIVOSUN 1.35-Gallon Pump Pressure Sprayer

This pump worked very well for what I used it for. I sprayed a cleaner for my wood deck. I would recommend

Purchased sprayer in 2021 and worked flawlessly until august 2024 when the o ring for the pump failed. Being pleased with the product i decided to buy another. When arrived It had an extra parts kit that had the o ring to fix the old sprayer. Now i have two sprayers that work great. Over the years i have purchased several cheap sprayers that did not last long. This product comes with one of the best user manuals. Simple, clear and easy to understand. Good product Vivosun

I've had two of these fine sprayers--lightweight and very functional. Both leaked due to MY over pressurizing. Leaks occur on the bottom, underneath the black part where the seam in the orange plastic is. Cannot repair them from the outside--no seal or glue I know of can withstand the pressure externally. DO NOT OVER PRESSURIZE! When pumping simply stop when resistance to the handle reaches a medium point. If you have to push hard on the handle, you're overdoing it!!! (Play it by ear, so to speak). I've seen same in other plastic sprayers, too. Some have pressure gauges on them to stave overpressurizing--but those are expensive.

I just returned a different brand that was so cheaply made that it blew it’s seal on first use. It was apparent that the Vivosun was a better made product immediately. It has a good range and good pressure.

Bought this last year and the first time I used it, worked great. Second time, the upper funnel part where you pour liquid in, kept releasing air while pumping it up. Had to use every bit of strength that I have to tighten this part down to finally get it to where it would not leak air and lose pressure. Then the third time, pumped it up and noticed when I used it that the manually adjusted sprayer nozzle had changed its pattern of spray without me changing it, but basically thought it was still usable. Then, when I went back to use it again, I noticed that there was a huge puddle, as it had leaked all over the place from the bottom. I noticed that many other reviewers have stated that there was a leak from the bottom as well. I think this is a design flaw and maybe that's the reason for the extra black sleeve attached to the bottom? I originally thought, from the heaviness and what appeared to be the sturdiness of the sprayer, that it was a quality item, but I was wrong. I think if it's going to split at the seam on the bottom from possibly too much pressure, as I can think of no other reason, then there ought to be a pressure limit with a pressure gauge indicator for reference. Spilling/leaking dangerous, toxic and poisonous chemicals all over is a very dangerous situation. I consider this a total waste of money, unsafe and am currently looking for a replacement and have no idea what to purchase as I don't want to get burned again!!! Extremely disappointed!

Works better than most!

It's a great buying opportunity, an excellent product.

Worked great until the o ring in the pressure pump came off. Then the hadke popped off if the internal pump rotating bit. The rubber flap that saves as a one way valve tore apart when attempt to gently remove to push the internal pump portion out to reattach to the upper portion. Worked great fir the few weeks that it worked. Still trying to figure a way to make a new seal. Lots of thistles need dog safe weed spray

Fonctionnement ras leger et pratique

Works great. I use it for seedlings, nice fine mist, easy to direct the spray.

Seems good quality but it is difficult to see how much liquid your putting in though with it being dark coloured held up to light but still couldn’t see .. but did the job I brought it for ..

I’ve been through a few sprayers that have been badly designed and broke after just a couple of uses. This one is in a league of its own - solidly built, at a good price, and works perfectly. Assembly is a cinch and shouldn’t take more than a couple of minutes. Once assembled the sprayer is easy to use, and gives you a consistent and unbroken stream. A nice touch is that they include spare gaskets in the package. I use this exclusively for the garden, although the box lists a few other uses. I doubt this sprayer would be very useful for cleaning a car, but for the garden it’s good value for money and a great sprayer.
