GravityWorks Replacement Reservoir Kit

I parced out a gravity fed kit versus purchase an entire one because I did something slightly different with it. I didn't need a clean bag, and wanted the tubes to flow directly from the filter to a Platypus Plus Bottle. We carried two of the Plus Bottles, and this worked perfect for our travels through central/south america for the last 8 months. It is compact, light, no pumping required, no iodine or chlorine, gravity fed, and fills a liter bag in less than 2 minutes. Here are the parts we purchased to make the kit work: - Platypus GravityWorks 2.0L Reservoir "Dirty" (https://www.amazon.com/dp/B00AZVMS72/ref=cm_cr_ryp_prd_ttl_sol_33) - Platypus GravityWorks Hose Kit (https://www.amazon.com/dp/B00453ULP2/ref=cm_cr_ryp_prd_ttl_sol_32) - Platypus GravityWorks Filter Cartridge (https://www.amazon.com/dp/B00453ULCA/ref=cm_cr_ryp_prd_ttl_sol_35) - Platypus Plus Bottle 1L (https://www.amazon.com/dp/B002EQDP96/ref=cm_cr_ryp_prd_ttl_sol_43) - Platypus Drinking Tube Kit (https://www.amazon.com/Platypus-07045-Drinking-Tube-Kit/dp/B000J2H8OA/ref=sr_1_2?s=sporting-goods&ie=UTF8&qid=1466879474&sr=1-2&keywords=platypus+drink+tube) The Plus Bottles took abuse, and were fantastic due to: - having a loop for a carabiner or hook to hang - water wouldn't 'glug' out of the bottle as with a rigid plastic bottle when it needs to fill with air, as this didn't need to refill with air - it took up only as much room in a bag as you had fluid in it, as you could compress the air out of it The down side to the system: - the bottles are difficult to clean, especially in third world countries where you can't find the typical items to clean them and due to it having a small opening - the bottles are showing sign of destruction (after much abuse) where the bag is adhered to the opening I would absolutely purchase this system and all parts again for lightweight traveling - it was perfect and saved money when we didn't have to purchase bottled water.

I use this as a dirty water bag with a DIY gravity filter based on a Sawyer mini and I LOVE it. I did replace the strap/buckle with 1.8mm Reflect It cord with a brummel loop splice and a dutch hook to reduce the bulk and because the strap seemed to hold water when wet. The wide mouth opening makes scooping up water from a shallow source really easy and the placement of the outflow means you can easily get most or all of the water out, easier than a bladder that has the outflow located on the front face (like most CamelBak bladders do). Platypus does make a 4L version of this but it's unnecessarily large and bulky. Normally I don't need more than 2L of water at a time and if I do I'd rather just fill up the dirty bag twice

Good system for filtering water. The zip opening makes it easy to scoop up water from a stream or lake. Great system for plugging in the tube which starts the flow. Concerned the clamp will eventually damage the tube. The zip closure is relatively strong but I’m Always worried it will open and leak when in my backpack.

This didn't come with caps even thought they are shown in the pictures. like other reviews, it's not even clear in the description it doesn't come with it.

This bag is the sorta soft and "stretchy" material found in the PlusBottle. Much better than the "krinkly" stuff Platy makes the regular 2liter soft bottles out of. I use it as a squeeze bag for the Sawyer Mini (or gravity-feed for same when I have time). Works great, as the zip closure allows the bottle to be filled in one dip, and hasn't come open despite much squeezing. I had to buy a male CPC fitting (search AZ for "Katadyn Quick Fill Adaptor") and re-purpose some hose, but now I can dip the bag, do some hookups, walk away, and come back to a filled 2l clean bottle. I have filtered about 20l using this system so far. FYI- Sawyer uses industry standard threads which match water and soda bottles, whereas Platypus uses proprietary threads on their Soft- and Plus-bottles (to lock you into buying their caps etc). That's why I bought this bag and connectorized it to feed the Sawyer: the 2l SoftBottle wouldn't seal against the standardized threads on Sawyer filters.

Bought this product to use on a series of 3-4 day backpacking trips climbing 14ers in Colorado. It was the perfect solution for our large family (7). We also bought an extra 8L set of bags to pair with the 6L set reviewed here. Our primary water sources were high alpine lakes and streams but occasionally we would need to use it at water sources around 8k in elevation. Generally, the sources were clear. The water passes through the filter quite efficiently and the stated 1.5L/minute seems accurate for our experience. We only used the “clean” bags on our first trip after which we ditched them and just filled our respective water bottles directly from the hose. Having two “sets” of bags ensured that no one ever had to wait for water.

I used this bag as part of my water system on an Appalachian Trail thru-hike in 2016. I kept it in the side pocket of my pack and attached the filter inline to a bite valve. This allowed me to quickly fill the dirty bag and filter "on the run" as I sucked through the bite valve. I had a quick-disconnect near the bite valve so I could gravity filter into a 1L Nalgene at night for a Nido (Whole Milk Powder) + Whey Isolate shake. Eventually, the female quick disconnect got stiff and would not allow the tube to turn. I didn't want to risk it breaking on me in the field. I ordered a new one and had it sent to me in New York (more than half way) to be safe. I still use the second one today (pictured).

I carefully read the item description about the 2l bag and it said I one place that only the dirty water bag was in this "kit." In another place it said you get both the dirty and clean bags. I can verify that you only get the dirty bag.

You get: one dirty bag with female quick connector (no male) and one clean bag with no cap whatsoever - just a threaded opening. You need to also buy the GravityWorks Replacement Hose kit for the cap and elbow fitting for the clean bag and the male elbow quick connector for dirty bag. It also comes with: one long hose (cap and male elbow elbow fitting on the one end with shut off clamp) and one short hose with male quick connect elbow fitting.

Price was expensive but items are quality.

Note the other reviewers, this kit only comes with bags. There is a quick connect on the dirty bag but the clean bag is capless.

Disappointed that there isn't a cap with fitting on it. For the money I would expect to get a cap on the clean bag. It's shown in multiple photos. But not included?
