Solo 475 Diaphragm Pump Backpack Sprayer, 4 Gallon Solo Hand-Pump Backpack Sprayer w/ Diaphragm Pump The 475™ is a virtually identical to Solo's popular 425® but it has a diaphragm pump mechanism in the place of the 425's piston pump. In practical terms, this means that the 475 is better suited to abrasive materials, since the diaphragm completely isolates the spray material from the inner workings of the pump mechanism. The other major difference is that the diaphragm pump develops a lower maximum pressure (60 PSI vs 90 PSI for the 425). Otherwise, the sprayers share the same features that make Solo backpacks our number one seller, year after year: High-density polyethylene tank with ultra-violet inhibitors allows for unmatched durability and ultra-violet protectionf Large 4.2 in. opening with filter baske Shut-off valve and wand overall length of 28 in. for hard-to-reach places 4 ft. of high-pressure hose Padded shoulder straps for greater comfort

You eliminate the common problem of "over spraying" applications. Another feature is the pressure gage visually shows you the spraying pressure while spraying. No guessing what the pressure is. The fold away handle is a nice feature when storing the sprayer. It eliminates having to take off the handle when storing the sprayer. The Solo owners manual is very complete. The manual incorporates a parts breakdown.

I found the Solo customer service and technical people very willing/able to answer questions. I have written to Solo and suggested they incorporate a carrying handle in the sprayer tank cap. It would make it easier to handle/carry the sprayer. Also suggested they use decal numbers in the gallon levels that are cast into the tank. It would make reading the tank levels much easier. 60" 2 piece brass wand, #TE1252 Nozzle Spray Boom,#4900514 - total width 33", distance between nozzles 24"4 Nozzle Spray Boom,#4900298 - total width 49-3/4", distance between nozzles 16"Shoulder Saver Harness,#4300314There are two shoulder straps for this sprayer.
