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

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 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.

I received this item and one of them had a factory defect. Their customer service sent me a replacement right away. great product and great customer service as well.

Good quality product. However one of the bags had a hole and leaked. Had to throw/discard one bag. Hope the bags are tested before packaged/sale. Ended with one bag short. Had to stop by local pool store.

Using these for pool cover and as I began to fill them with water 2 of them immediately started leaking because the seams between were not sealed. If the seams hold up they’ll probably last for a few years just leaving out a few months. My biggest disappointment was when I reached out to the manufacturer they wouldn’t just replace the 2 defective ones, 3 of them already have water in them. So now I’ll have to get a replacement order… 3 out of 5 stars because 3 of them held water..

I was looking for something to hold down my pool cover. I bought these and they did the job. They were easy to fill, sturdy, and came at a fair price. I would definitely buy again.

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.

All perfect but one of the product was not good I filled it with weather it doesn’t hold the water. I don’t think they will send me one. Nowadays no one cares if the product is good or bad and I’m not gonna cry for a bag I put a few bricks holding the cover. Thanks anyway disappointed

Bought this in two diff ent lengths and both are damaged and leaky. Waste of money. This shop should not be allowed to sell on Amazon.

Brought 6 and 5 leak at the seams so all the water leaks out

Lasted one season. Stored correctly bought six three punctured year two.

I ordered the 5 packs. Upon arrival 3 out of the 5 water tube leaked. Amazon sent another 5 quickly for replacement. I handled the new pack with extra care due to bad experience from the first pack, but First 1 from the replacement 5 pack leaked again. 2nd one from the replacement pack was ok, and since I only need 3 in total I did not bother to try the last three from the new package. They are pretty fragile and probably will only last one season.2 stars because well, out of the 7 I tried only 3 worked. At least Amazon replacement was quick.

Warmth???The bags, made in China, seem thinner than our previous purchases. I expect this means they won’t last as long. Hopefully long enough to make the value-price ratio reasonable.
