    Water Tubes

    1. 4 years ago
      Finally a good water tube !
      I purchased 7 Ultimate single water tubes in September and none of them are leaking so far. I have had bad luck with poorly made water tubes,but the Ultimate single tube has lived up to it's name so far.

      Does the job
      I have a safety cover and these help prevent debris (leaves) from getting underneath. It definitely helped keep the pool cleaner when I reopened in the Spring. 4 out of 6 tubes (purchased in 2017) have lasted into season 2. It might be the tubes and weather - it might have been my darn cat! Regardless, buying more.

      Best time saver yet
      After 2 off-seasons with water bags, I just got enough of the aqua blocks to cover about 3/4 of the perimeter, thinking I could use the remaining bags that had not already broken for the rest. I loved the 3 sides that got aqua blocks, and cursed the entire time on the side with the bags because it took twice as long as the other 3 sides combined, and got me all wet! I have already replaced 2 bags due to leakage in the last 2 months. Next year, it is all blocks, all the way. Any money spent on ... read more the blocks will be made up in time savings with your first install and spring takedown - definitely a must purchase for people like me who HATE pool maintenance!

      Awesome replacement for water tubes!
      Bought these last year for pool closing after being tired of the tubes losing water all winter. waited to post this until winter went by us. We just opened pool yesterday, they all survived full of water with zero cracks. Drying now to be stacked and stored for next year. Love this alternative!

      Finally, something that works
      With living in the windy north its very had to find something that actually works and holds the winter cover down securely. Those blue bags need to be replaced every year and get costly. The Aqua Blocks worked wonderfully. Lids don't snap on well but we used large zips ties to solve the problem. Through all the wind and snowstorms the Aqua Blocks didn't move! Nice to open the pool and have hardly any worms. Buying another dozen this year.

      They Work Great!
      I had bought some of these plugs when we first set up our 18' above ground pool and they worked great. Now, 8 years later they finally got weather cracked and needed replacement. You can't beat the price considering they kept water from leaking out during the winter for many years. The only change is that the wing nut is now plastic verse metal from 8 years ago. The new plastic wing nut worked great and should last as long as you keep it out of the sun during the summer.

      Perfect fit
      A simple thing like plugs often give us fits - the wing nut turns the screw and they don't tighen or the rubber cracks - not the case with these, installed them out of the package - perfect fit and operation

      Good selection with quick service. Good value for money

      Good Sturdy Water Tubes
      I like the thickness of these bags and feel confident they'll hold up nicely during our Northeast winter weather not to mention so far they are immune to the squirrels that run over them trying to get a drink of rain water that accumulates on the pool cover putting little rips in them as has happened with lesser quality bags. I also like the double sided feature just in case something unforeseen should manage to tear one side the other side still holds enough water to keep the cover securely in place.

      Better Water Tubes
      Just installed 6 of the Ultimate Water Tubes so I can't say how long they last. In the past I used the cheaper water tubes and some of them leaked right away. Most of the cheaper tubes didn't last a full season and I decided to get the Ultimate Water Tubes to avoid regular replacement. The new tubes are heavy duty and heat sealed on all edges. They appear to be far less likely to leak especially on the corners where to cheaper tubes tend to leak the most. The caps are a lot easier to close than ... read more the cheaper tubes and they appear to seal very well. After trying these water tubes I think they are well worth the extra expense.

      Great Customer Service!
      I ordered a dozen of the 10' tubes for my 20' X 40' pool. I used to use sand bags and various cement block to hold downy winter cover. These take a little more to set up but once they are set up my cover is locked down tight. Of the 12 I ordered 2 of them leaked on one side within a couple days. I sent a quick email to In the swim with my order info and pictures of the faulty tubes and they immediately sent me two replacement tubes. I didn't even have to send them the faulty ones in order to get ... read more the replacements. That is awesome customer service. I will try to remember to update after the winter to see how these tubes hold up in the elements.

      Corner tubes
      We bought 4 of them. They worked out very well but the next day when I checked, one of them was leaking. There's a hole somewhere but I can't find it.

      Recently purchased water tubes for my pool cover product is awesome and the speed that you receive what you ordered is beyond words. Ordered a few times from in the swim and am amazed how quickly I receive my order. Great company to deal with.

      Good Product - Good Price
      Just closed the pool today and did use a couple of the new corner bags. Easy to fill and the caps closed first time. Bought extras becase the Lab cuts the corners too close some times when chasing his frisbee.

      water tubes
      this was the second batch of water tubes I ordered this year, was a bit disappointed as the 10' were a different shade of blue and did not seem to be as sturdy as the first batch I had got, checked and it was same order number so not sure what happened. But overall am happy to use them on the pool, they hold the cover great and are easy to use.

      A Pool Necessity
      I have tried several different methods for keeping my pool cover from caving into the pool over the winter. I have found that the single tubes work the best. I have used the double in the past, but when the single tubes are more flexible for my irregular shaped pool, and when it does leak-and they all do- it is easy to spot and replace.

      Great purchase
      We had some of these previously which we used for 15 years and we liked them because of their efficiency so I was very pleased to find them in the "In The Swim" catalog. I ordered them now so that we are ready when it comes time to close the pool. They do the best job of anchoring the winter pool cover down.

      Great Service and Product too!!
      These tubes were exactly what I was looking for. I have used these tubes for years and they work perfectly for my pool closing. The delivery time was unbelievable. The tubes were on my front door step in no time at all. I ordered 8 tubes and one was manufactured incorrectly. I contacted customer service and a replacement was here within 2 days. Now that's service! I do wish the individuals who pack the tubes would be more careful to not crimp the red rubber stopper for filling. The crimps made ... read more the initial connection difficult but the next time the holes will be re-formed and should be no problem.

      Returned item
      Even though I use clips with my above ground cover, I purchased this item to help with the north winter wind. I could not keep the water tubes from sliding off the pool caps and down on top of the cover or sliding over the pool caps out on to the ground. These would work well for an in-ground pool where surface was flat and even with the ground. Therefore I returned this item. Did not work well for me.

      Durabilaty of water tubes
      The water tubes for stablizing the winter cover for my inground pool were priced reasonably, easy to place and very durable. Heavy rains fell before the snow season, and the tubes held well. None of the tubes broke down as others I have had did. Accolades to your company from a satisfied customer!

    In The Swim Knowledge Pool: Pool Cover Water Tubes

    In The Swim's Dr. Pool

    More about Pool Cover Water Tubes

    Water Tubes are an affordable way to secure your solid inground pool cover or winter pool cover. Water Tubes are vinyl water bags filled 2/3 full of water and laid on top of the edges of your inground pool cover.  Double tubes lay flatter than single tube water bags to avoid rolling on sloped pool decks, and are still usable if one chamber gets popped. Pinholes or tears in water tubes can be repaired easily with Flexible Sealer

    Winter water bags work as pool cover weights to hold your cover down against snow, rain and wind to prevent debris from blowing into the water. Water tubes can also be used with safety covers, to keep debris from blowing under the edge. As an alternative to pool water bags, see our unbreakable Aqua Blocks, plastic containers that will never leak, and stack for easy summer storage.

    Please contact our pool experts at In The Swim if you have any questions regarding how to close your inground pool and we can help you find the right winterizing supplies for your swimming pool! Call us at 1-800-288-7946!
