Customers are dissatisfied with the flow of the pump sprayer. They mention that it sometimes hesitates in siphoning fluid, and the flow pulsates. They also say that the flow doesn't restart immediately when they release the spray grip.

I have been a mechanic for 56 years. I have use very conceivable syphon pressure gun known to mankind! Some decent, some good, but none great - and all inexpensive. This particular model I decided to "go the distance" and pay the high price just to see how well it performs. Folks, I was impressed!!! This unit works flawlessly. It is made with quality materials (as opposed to the cheaper ones I have used over the years). You can adjust the spray tip. The syphon hose does not fall out of the liquid container (because of the weighted end). It works so well I had to write this review. Cannot go wrong with this purchase, although I agree is is somewhat pricey.

High quality tool. Siphons and sprays at a very controlled rate of flow. Does an excellent job of fine detailed cleaning. I'm going to use this one around the house and yard. I just used it to clean my engine bay in the truck. Used a degreaser and then plain water. Worked great and hardly used much liquid both times. It has hundreds of uses. Looks like a machinist hand crafted the thing. Fits well in your hand and easy to maneuver around.
The siphon tube is very tough and durable with a brass dip tube. Smart idea! The tip is adjustable for spray pattern but I'm still playing around with that one. I'll update as projects come up. It requires 100 psi and at least 9CFM of compressed air so make sure your compressor is capable of supplying that.

4.0 out of 5 stars Works well
Reviewed in the United States on August 9, 2019

Before I purchased this, I hesitated because many of the reviews said that it didn't spray hard enough. I think their problem may have been the compressor pressure and capacity. I have a very hefty compressor that let me use 120 psi and keep it going. I used this to clean the thick grime of grease from my old sports that had never been cleaned. It worked as well as a pressure washer. The only thing you have to maintain is a heavy buck to toe around with you as the hose for siphoning the liquid is not extremely long. Also, find a way to keep the siphon rod at the bottom of the bucket. Finally, If you are up above the bucket level, expect the fluid in the mechanism and tubbing to drop down into the bucket. That only means the flow doesn't restart immediately when you release the spray grip.

Updated - I just bought another one as a gift for the mechanic who helped me work on my airplane. He was really impressed with the quality and the performance of it .

****************************************

I was worried that real spray guns had disappeared in the face of political correctness but this is beautifully made, very effective and feels like it will last a lifetime . Many uses for those with a supply of compressed air. Not to be confused with the weak substitutes .

I use it to clean the rims and engine on the car, clean junk off the patio , spray plants to remove dirt, clean bike and a host of other projects.

Nozzle is adjustable Machining of the parts is awesome . A thing of beauty. Great for spraying most anything from solvent to soapy water

5.0 out of 5 stars Used for spraying degreaser
Reviewed in the United States on May 24, 2022

I wasn't sure what to expect when I hooked this up to my 100 PSI compressor. It handled the pressure great, but why wouldn't it. The nozzle can be tightened to adjust the spray, a small amount. The trigger is comfortable and the hose to the liquid is sufficient.
Now when you think of cleaning with it. It couldn't spray the bugs off my bumper but when used with a degreaser it did clean up my old engine block decently. This will by no means replace a pressure washer. Plan to use this for basic cleaning. Like soap and water, with a good brush. Then you won't be disappointed.
I won't use mine too much and it's small and easy to store, great product!

I had purchased this siphon sprayer to aid in cleaning the engine block and other major engine components during a recent rebuild I completed. I had initially bought a cheap Harbor Freight version of this (approximately $11) and it did not work well. I was a little skeptical that this would provide similar results and I was proven wrong. This thing worked great, never leaked, and was a huge help in blasting solvent through oil passages in the block and crank, as well as cleaning water jackets on the block and head. Completely happy with the purchase.
