Easy to use and assemble . Spray is very consistent and works extremely well . I highly recommend Review: Very good sprayer, but a few suggestions. - 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. ## Features - Top Quality Material - Easily and effectively handles disinfectants, bleach solutions, fertilizers, herbicides, pesticides and formulations for tree, shrub and plant protection. - High-performance diaphragm pump for use with wettable powders, liquid and bleach solutions.

I called for over a month, everyday, was told everytime that the warranty person is unavailable and that he would call back. 2 weeks after that, some kid called and of course I was in the field unable to answer the call and that was his only attempt to call me. Due to the decline in quality of this once great product I can not recommend it to anyone. **Q: Does this sprayer produce up to 60psi or 90 psi? It says 60 one place and 90 in a other.** A: Unsure how to measure the psi. And sprays really good that’s all I know **Q: Does this 475-B come with a back strap with a waist belt?** A: It has a chest strap no waist belt **Q: Will the diaphragm last longer than the piston pump? My piston pump leaks all the time.** A: Diaphragm pumps tend to last longer, create more pressure and can be used for wettable powders, etc. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Pump and spray !!! *by O***Y on August 13, 2025* Pump sprayer is very well made .

The sprayer arrived in good condition, added the spraying solution and went right to work. The he sprayer works great. ## Frequently Bought Together - SOLO 475-B BACKPACK SPRAYER, 4 GALLON, DIAPHRAGM - BLEACH RESISTANT - Solo 4900170N 28-Inch Universal Sprayer Wand And Shut-off Valve, Black - Solo 0610406-K Diaphragm Sprayer Pump Repair Kit,Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/6172617-475-b-backpack-sprayer-4-gallon-diaphragm-bleach-resistant](https://www.desertcart.pl/products/6172617-475-b-backpack-sprayer-4-gallon-diaphragm-bleach-resistant) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-27*
