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.
Review Summary (Based on 6 Reviews)
I purchase this sprayer fom A.M-Leonard on 08/06/1990 and have used it a couple times a year, every year. It's starting to leak a little so time to order seals. 22 years and still can get parts and they make the unit. Nice.
Lever on piston broke right after warranty was up.
A.M. Leonard: The customer was contacted and send a new part for the sprayer.
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.
