Less back pain-stress with 61900

I work for a major pest control company and have over 30 years experience in the industry. My company has recently switched from power spray units to backpack sprayer units for exterior applications.The company provided solo units that do not have adequate shoulder padding, support and after a day of 6 or more applications my back was killing me. I decided to buy my own unit and when I found your site decided to buy the 61900 model based on the features listed, mainly shoulder straps and padding. I am extremely pleased with my sprayer. As soon as I strapped it on I felt the difference. The back padding, waist buckle, shoulder padding and shoulder buckle make all the difference in relieving back stress. I like the spraying features of the 61900 also. Pressure gauge, length of hose, sprayer wand, and adjustable tip. All in all an excellent sprayer .

Good Service`

Received the Chapin 61900 in a very timely manner. As a precautionary measure, I filled it with water and allowed it to sit for a few hours. Upon inspection, I found that it had a significant leak around the bottom flange clamp. I tightened and retightened the clamp several times until there was no further room to tighten. Still, the leak persisted. I then called the factory and spoke with Linda in customer service. She advised me to follow the instructions in the manual and to disassemble the unit, a task that I found very easy. Upon disassembly and inspection, I found that the bottom "O" ring had been pinched by the plastic reservoir body during assembly. I applied copious amounts of petroleum jelly to all parts and reassembled the unit. No leaks. I called Linda again and advised that the unit was not leaking, but was likely going to leak due to the pinched "O" ring. She made certain that she understood which ring was problematic. She then sent me an entire repair kit with all gaskets, "O" rings and other miscellaneous parts that might be required in the future. So far, no additional leaks. The unit works as advertised. Good, quick service after the sale. I would purchase another Chapin unit.

Works perfectly so far

I have used this sprayer twice for weed control (received it two weeks ago) and am very satisfied so far--it is easy to use, appears well constructed, and not hard on the back. I would recommend it to anyone considering a backpack sprayer.

Chapin 61900

First, the unit I received, the strap was not assembly properly in the factor - and the replacement was no better. What Chapin doesn't tell you is that their backsprayers do not hold pressure and you have to continually pump the unit to maintain the pressure - this is very annoying and not easy to do. In all, I would not recommend this sprayer.

Chapin 61900 Commercial Backpack Sprayer
By Sean on 02/23/2011

Pros: Great product!!! I was able to cut my spray time down to a fourth of the time it usually takes. The 4 gallon tanks eliminates having to stop and remix as you would do with the smaller sprayers and the pump allows you to continue spraying on the go while pumping at the same time. This was a good investment. Cons: the spray wand does not attach securely to the wand holder on the bottom of the back pack sprayer for storage.

The main difference between the two is that the Chapin 61900 Tree/Turf Pro Backpack sprayer has a stainless steel wand, and the Chapin 61800 Pro Series 4 Gallon Backpack sprayer has a plastic wand and nozzle.Typically, if this were to be used for a company at a customers house, they would want the 61900 Pro Sprayer because the stainless steel looks slightly more professional but doesn't necessarily mean it sprays any better.

I understand the difference in wand material - I'm just trying to confirm any additional differences. Thanks.
The 61800 and the 61900 both have a pressure gage. The 61900 does come with the deluxe padded shoulder straps while the 61800 comes with the basic unpadded straps. Below is a link that will allow you to see a side by side comparison of the sprayers:

Typically, the Chapin 61900 Tree/Turf Backpack sprayer can reach only about 10 feet if you turn the nozzle to the pinstream setting which just shoots a thin stream of water. We do carry a Chapin Slide Pump Sprayer which can reach targets over 30 feet away.
