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. ## 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? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.fr/products/6172617-solo-475-b-backpack-sprayer-4-gallon-diaphragm-bleach-resistant](https://www.desertcart.fr/products/6172617-solo-475-b-backpack-sprayer-4-gallon-diaphragm-bleach-resistant) --- *Product available on Desertcart France* *Store origin: FR* *Last updated: 2026-09-20*
