## Questions & Answers

**Q: Does it come with water?**
A: What type of water does it come with?

**Q: How to clean the hose?**
A: Cleaning the hose is different from cleaning the bladder. 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. .
