## Description

The SOLO® 425-DELUXE, with a connecting rod-actuated piston pump, can produce a wide pressure range of up to 90 psi with an optional plug # 4200215 (not included) and is capable of performing virtually every spraying task. Easily and effectively handles liquid disinfectants, fertilizers, herbicides, pesticides and formulations for tree, shrub, and plant protection. Built for comfort. Built for convenience. Built to last. SOLO's ergonomic design contours to your back for greater comfort. With a proven piston pump, you will be reliably equipped for applying spray liquid or insecticides in your garden. A low number of wearing parts and sturdy technology ensure a long service life and minimum maintenance. The large filling aperture for convenient filling of the tank and smooth-running pump make spraying pleasant work.

Review: Solo backpack a winner - The Solo 425 Deluxe is a great performing sprayer. Glad I got the deluxe model as it has a pressure gauge, a brass nozzle, and padded shoulder straps. I use it for herbicides and it reaches far enough to spray blackberries with enough volume that I otherwise could not reach with my old small hand-pump sprayer. The hand pump works really well and is easy to operate without taking the backback off. Obviously it is heavy when filled to capacity, so I only put 2 gallons in which lasts a long time. Finally, the Solo is easy to clean. Great tool!

## Questions & Answers

**Q: I want to reach the top of my roof. Does 60psi reach 25-30 feet?**
A: Yes, the 425 models will reach out to the 25-30 foot range using a stream spray pattern.  When longer distances or greater height is needed, Solo also offers a variety of extension wands of up to 8 feet in length to accomplish those tasks.

**Q: What runs the pistons or diaphragm?  Gas or battery?**
A: Neither one.  Pumping the handle gives you the spraying power

**Q: Where can I get all the parts names. I have one part cracked and have to replace**
A: You can find part names in the instruction booklet or on the website.

**Q: Can I use bleach in this sprayer**
A: I think that would be OK as long as you thoroughly clean the sprayer after its use.
