    Changed valve...

    Posted by Logan Wilder on Feb 11th 2021

    I bought 2 of these a couple years ago and they have been great. After getting 3 new ones I noticed immediately that the qd valves have been changed and are no longer compatible with any of my qd fittings from other brands. I had not planned on even using the included fittings because they seem a little cheap quality wise and I wanted to use my valved fittings. Now I have two different sets of bags that are incompatible with each other. My only other complaint is that the valve is placed a little higher on the bags than I would like (it's to prevent sediment from entering the filters) I think they would ideally be about an inch lower. Other than that they are absolutely worth it and are by far the best value for a gravity filter.

    Love it!

    I am so excited to have this on hand. It's great for emergency situations or for general water filtration. I now don't have to worry about having clean water.

    Bought the Hydroblu gravity bag system, and two weeks later the town's water main broke! We were ready and didn't have to boil water. The system works well at home if hung from a sturdy closet rod with a plastic tub underneath it for spills.

    Great Filter...

    Purchased and used the versa flow system on a recent camping trip. It worked like a charm. The 10L bag made it easy to collect water and the gravity feed made it easy for everyone to get water for their drinking/cooking needs. I highly recommend this system.

    Flow rate is better than similar products I have owned. Love the capability to backflush in the woods.

    A year or more ago, I got a couple of the Go Flow Water Gravity kits for myself and one for my best friend and her family. They went camping, used the Go Flow, and loved it; her husband, an experienced camper, was very impressed with it. This year I got Go Flow Water Gravity kits for another friend and for my mother, since they both live in hurricane country and the season is starting. My other friend is a single mother, and my own mother is on a small fixed income; neither of them would be able to afford one of these kits on her own, and both were very glad to get one. Giving a water filter as a gift says more eloquently than words can, "I love you and I want you to stay safe." And for someone who doesn't have a lot of money, being even a little more prepared gives a peace of mind that nothing else can. The Go Flow Water Gravity kits make great gifts.
