SOLO 475-B BACKPACK SPRAYER, 4 GALLON, DIAPHRAGM - BLEACH RESISTANT

Pump sprayer is very well made . Easy to use and assemble . Spray is very consistent and works extremely well . I highly recommend

Super happy

Works good, the hand pump is not bad but not great Make sure to clean it out before winter or gunk will build up when you pull it out in the spring. Wish it was easier to disassemble to clean up

great sprayer

I’ve had a solo sprayer for years & recently purchased another for church property use. I find them to be well built and dependable. I offer a couple of suggestions however. First, there are no instructions included, although it’s fairly easy to assemble, it wouldn’t hurt to include a little one page instruction sheet. Two, it’s difficult to see the gallon indicator on the tank, as it is the same opaque color as the tank. Having the gallon indicator marked in black would offer a contrast, making it much easier to hit your tank fill mark. I colored mine with a sharpie.

Easy to use, well built, good materials. This beats little squeeze bottles all hollow. You work the the lever a few times (very easy, no strain, comfortable) and the unit sprays for a long time. Really, it is effortless and you can cover a large area fast. There is no leaking whatsoever. They could have made the various tips for the nozzle easier to put on and off; you have to disassemble the tip a bit and a simple screw on/off would have been far better. That said, I think there is only one nozzle you will ever need, the one that sprays a flat fan shape. Don't know why, for example, anyone would want to spray a _stream_ of weedkiller. I fill the thing with it sitting on a table so that I can slip into the straps easily and walk away with it instead of bending down to get into it. For what it's worth I bought a knockoff of Roundup from Amazon and it gives excellent results. That would be Compare-N-Save Concentrate Grass and Weed Killer. The products are virtually the same chemically.

This backpack sprayer is not one I would consider worth the money. I received a damaged one right out of the box. Amazon replace this with a new one. The new one worked for ONE use and on the second use, the connecting rod cracked and broke. This repair, even if Solo warrantied the work would require me to disassemble the diaphragm to fix. This i completely unacceptable. Solo was contacts over email and phone and no response was received. I never got in contact with a person. This is generally light duty plastic junk. I don't recommend this unit.

After starting, decades ago, with a metal 2-gallon pump sprayer, I bought a Solo piston sprayer and loved it. Unfortunately the piston system wears and begins to lose functionality, so I bought the diaphragm model and love it. It has given me many years of dependable service. However, I'm getting older and the straps became uncomfortable on my shoulders so I bought a replacement "harness" with better shoulder padding and cross straps to align the shoulder straps. Problems solved and at age 72 I'm still going strong with it.
