Blue Wave 10-ft Double Water Tube for Winter Pool Cover - 5 Pack

The tube's were delivered on time as promised. They do the job of holding the pool cover in place. Two of the tubes had small leak. The vendor was very helpful and promptly sent replacement tubes.

I bought these hoping to use them to hold down the cover of my pool and not do something janky like using old pavers and bricks... Oh well. The valve/openings are poorly manufactured and are misshapen making it almost impossible to close them. I'm a reasonably strong person and had a VERY hard time getting them to close. If you don't put them down like laying a baby in a crib, they burst open or the bottoms completely blow out. Over the course of a few days at least 90% of the water leaked out rendering them completely useless. My back yard is now littered with broken and deflated tubes frozen to the ground. As soon as it warms up, I'll get them into the garbage. Thankfully I have enough old pavers and bricks around to hold down my cover. The one (out of 10) that has not exploded or leaked out, may make fun pool toy if filled with air next Summer.

They work great around my pool.

I have been purchasing these for years. Generally, a few of these fail by the end of the season. I do have a few that have lasted for several years. Most times, only 1 tube fails, so it is still usable, but not as heavy as both tubes filled with water. This year, I replaced all the old tubes with new ones. Hopefully, most of them will last. I am keeping the old ones that have both tubes that aren't compromised, just in case. Fortunately, they are pretty cheap, so just call it one more cost of owning a pool. These are very effective. They do the job they were meant to do. They are just very fragile. Don't drag them on the ground if there is any amount of water in them. When they are brand new, the caps are a hard to deal with. Closing them can be a hassle. After they harden up though, they are easy to open and close.

The water bags do not hold up. this was the first year I put them down and four of the 10 got holes in them over the winter. The tubes need to hold up better.

This was installed last Saturday. 3 of the tubes leaked immediately at the seam, located at the end of the tube furthest from the infill. Two of them double tubes leaked at one tube; and the other tube leaked at both tubes. it appears to be a mfg issues when the ends are seamed together. I don't have time to return with 22 degrees tonight, We are trying to glues them to get them to stop leaking. But other than that, this is a great idea. It held down the cover and up to the 50mph winds we get.

I purchased these on October 30th, as a five-piece set, well in advance of my winter above ground pool closing, so I'd have them available when I was ready to close my pool. Unfortunately, that meant that I didn't unpack them and fill them with water until this past weekend. Quality/Useability: Two of the five (20 feet of pool cover tubing) were duds out of the package. The first 10' tube had a split (>3" long) in one half of the two-tube system, right at the center vinyl-weld seal, the other 10' tube has a seeping leak around the outside, best I can determine, at the filler neck. I was very careful to open all of these on a heavy tarp to ensure they were protected while I test-filled them with low-pressure running water, before un-filling them and placing them on the pool ledge - so it was immediately apparent that these two issues were due to a manufacturing defect. Since these are designed to "counter-balance" each other, over the pool cover and on top of the pool ledge, having only one of two tubes filled with water makes this pretty much a non-starter when only one tube-side is functioning. Not sure the seller will help here, but having 2/5 of a product non-functional, out of the package, isn't the way to sell product. Caution: Above-ground pool install, with some or no decking, is not for the weak. My pool is 18'x35' (~100 circumferential feet) x 55” to the top of the ledge. Only 1/3 is decked and the remainder is open-sided. Water, in quantity, gets heavy, and these tubes are very flexible when filled, so forewarned is fore-armed. Having done this by myself, I strongly recommend doing this with two people for ease of install. Otherwise, plan on a full-body workout before you finally get these settled into place on the pool ledge. :) Install: Lay these out flat on the pool ledge, put two tube sets, with the filler necks adjacent to each other so you'll be able to fill both tube sets (four tubes) from the same location. You want to gently fill these, not flood them quickly - a 1/2" stream of water seems to work best. Make sure you have some way to turn-off the hose at the hose-end - it just makes it a lot less "wet" - then fill them to 1/2 capacity (recommended to ensure that they don't burst during freezing periods). If you're doing this by yourself, be prepared to stop filling, and catch/shift the tube so it remains on-ledge. As water ebbs and flows back and forth in the tube, it will cause the double tube to shift, and in many cases, to drop-off into the pool and cover. It can also go the other way and fall off completely so be prepared for either eventuality. Having an extra helper would definitely help to keep the tube on-ledge, and to help shape the tube to the ledge contour as you’re filling them. Alternatively, with two people, you could conceivably fill the tube with water, then, together, hoist it into place and adjust it on the ledge. Final Thoughts: While these are made in China, I had hoped for better quality control on the end-product. It was frustrating that two of the five tubes were bad – it took 1/5 of the coverage out of my winter cover protection system until I get these replaced. In the interim, I’m using bricks wrapped in towels. If these last through this season, I’m going to re-think using these, as the utility just doesn’t seem to be there. Note: I also purchased a 5-pack of 8' double tubes from another seller, those were perfect.

After fighting winds for years in my above ground pool, I finally lined the inside with these tube's. They work great, but I had to tie them to the sides all the way around so they don't slip. I wish there were grommets on the tubes.
