How many gallons per minute can this sprayer shoot maximum? Minimum?

Asked by Kato June 12, 2015

Answers

The maximum GPM is 1/2 gallon per minute with a standard nozzle at 90 psi. But you must bucket test any sprayer especially when changing out nozzles. Keeping at 90 psi can fluctuate based on how well you pump the sprayer so you can only ascertain proper calibration by the bucket test.

Sprayed with this unit 2 times overs a couple of months. First application was neem oil - super mild - no problems. 2nd application was a synthetic insecticide - unit sprayed fine during rinse - however diaphragm somehow split between rinse spray and application so I ended up with a pesticide spill that started with the back of my legs! Thanks for tricking me into paying you to poisoning me with this terrible product!

This is my second Solo backpack sprayer. I still have my first one after 23 years of use. The old one was beginning to get a little weak. I ordered it online through the Home Depot and it arrived at the Bainbridge Georgia store in just 4 days.

Out of the box, it was missing the bolt to attach the pump handle to the piston. That should have been the first clue. I figured it was no big deal, and just used a bolt I had handy. But the pump suddenly stopped working after spraying only half a tank. Worthless garbage

Bought this about 3 months ago and have used it 4 times. The straps hooks didn't attach to the bars and kept falling off, making it difficult just to get the thing on my back. Today, the pump won't pressurize at all and I will have to buy a pump repair kit for $20. It takes a long time to disassemble and put back together. Engineering and quality are terrible. Regret purchasing it.

SOLO Model 425-101 purchased March 2020. Leaks with Engineering Flaws in Manual Pump Mechanism.

I tested this tank with only water after reading the reviews of leaks. Out of the box, I attached the pump handle and spray nozzle to hose. It immediately began leaking at the bottom of tank above the pump mechanism. The two square foot puddle of water formed within 10 seconds after the first pump. I tightened all screws, but that did not help. Went online to watch any videos that would help determine how the parts are put together and to determine where the leak was coming from. Took apart and gained access to internal parts. Tightened the internal pressure bottle by turning it further 180 degrees, but pump slit opening was on the opposite site of where it needed to be so I installed the hose opposite side of where it was originally. After putting it back together, the leak appeared to stop after pumping. After filling it up with only water and testing again by walking around driveway and using the pumping handle, the leak returned again after 10 minutes. The leak was a lot as I could see it on the driveway and if the tank contained chemicals, my back would have been scarred as my clothes were soaked. Very disappointed in this product. I will return it to the store. Not sure if I want to purchase and experiment with another SOLO backpack product model that looks like a better design. Will try to attach image below to show leak location and design flaw.

I recently purchased this product at HD. I needed 4 gal. sprayer for home and farm. I should have done my homework and looked at past reviews. this product is poorly constructed. I thought I was doing a good deed by buying American. I will never purchase a Solo product again and recommend others stay clear as well.

I purchased this sprayer as a gift for my neighbor who does my lawn care. It handles most every job! It has been a real time (and finger) saver for applying weed killer, fertilizer and pesticides. The wand has a high reach for treating my tall trees. It is on it's 3rd season and doing great. No leaks! I highly recommend this brand.

I bought this a HD figuring I could do a lot of spraying with 4 gal. That is true, but I'm unable to pump while it is on my back and have to unload it each time it requires pumping, WHICH IS ABOUT EVERY MINUTE. This thing is more work than its worth. No human factors engineering in this design. One star is way too much. Used it once. Bought another sprayer
