FAQ
QUESTION: Can you spray wettable powders through a 425?ANSWER: No, WP's are too abrasive for a piston type sprayer. For wettable powders we recommend the Solo 475.
QUESTION: Will the plastic material last?
ANSWER: Only high density polyethylene is used. The material is chosen for high molecular weight, high impact strength, and excellent resistance to chemicals and stress. Ultraviolet inhibitors are used in the material to reduce deterioration caused by sunlight.
QUESTION: Can I use weedkiller and insecticide in the same sprayer?
ANSWER: In theory you can, if the sprayer is thoroughly cleaned out with an ammonia:water solution of 1:25. In practice, the use of both types of chemicals in the same unit is not recommended as the risk to plants can be high. Use caution when handling any type of chemical and when cleaning your sprayer.
QUESTION: Does the unit require constant pumping?
ANSWER: The well-designed lever action greatly reduces the pumping effort. The pressure cylinder within the tank has a hydraulic effect. Liquid from the pump compresses air in the pressure chamber which allows irregular pumping action, yet results in steady spray at the nozzle.
QUESTION: Can you use bleach in this sprayer?
ANSWER: No, the vendor says it ruins the o-rings.

Customer Reviews
I bought it to help me with big spraying jobs. The good thing about it is that you don't have to stop and pump a hand-held sprayer, you can just keep going. The thing I don't like about it is that it leaks on me right where the hose connects to the tank.
I really like the sprayer as far as I can tell. I really won't use it until spring.
21 years ago I bought this sprayer off of A.M. Leonard back in Aug 1990. I have used it spraying every year Round Up and Crossbow. The best sprayer I have owned.
Even with a few flaws it is the best I've used for the dollar spent. 1) When pumping the handle, any hardware I carry on my belt is sometimes in conflict with the handle. 2)When I received the newest unit (I have 4) the plastic piece holding the bottom of one of two straps was broken, but quickly replaced by AML. 3)As long as you triple rinse the piston with clean water it will last for years. 4)After several years of use it may be necessary to add hex nuts to the handle bolts and there is some difficulty with space to accomplish this. 5)I've run diesel, suspensions, WP's, and soluables through this sprayer. As long as you do a good clean up it will work.
