You can clean the hose with a long handled, narrow bottle brush. The hose unclips from the bladder which means you can directly clean as much of the hose as your bottle brush will reach. There are several suitable bottle brushes available on Amazon. Searching for "Munchkin bottle brush" will return some good options. **Q: What proof is there that this is pba free and will it fit in my walmart ozark trail outdoor equipment backpack?** A: the test report release by SGS, Report No. is GZHG1411043611SP.and we don't know if WACOOL 3L bladder will fit in your backpack,you can measure the backpack`s interior space and then compare it with our bladder's flat size. **Q: What's the trick to make this thing stop leaking? Carried it hanging in my ruck, and the bar separated from the bag. Screw top also leaks...** A: Make sure you slide the bar tightly against the bladder's plastic top, doubled over. Don't touch the bar while hiking. I don't know why the screw top leaks. Make sure you tighten it securely. . --- ## 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/63843824-wacool-3l-3liter-100oz-bpa-free-eva-hydration-pack-bladder](https://www.desertcart.pl/products/63843824-wacool-3l-3liter-100oz-bpa-free-eva-hydration-pack-bladder) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-06-03*
