      Winterize Without Having To Drain Your Pool

      This revolutionary pool valve has a unique one-way design to keep water from entering the return lines. There’s no longer a need to partially or completely drain your pool to clear the water out of your pipes — instead, replace your “eyeball” return fitting with this one-way valve, drain the water from the lines, fill them with antifreeze and rest assured that they won’t refill with water and freeze over the winter.

      Compatible with the Aquador skimmer cover for winterization, this valve lets you blow out the return lines while it’s installed. Featuring a durable, Buna-N O-ring, this winterization valve fits 1-1/2-in. threaded wall returns and pool cleaner fittings and won’t deteriorate or move like rubber plugs. Great for in-ground and above-ground pools alike, this winter pool valve will save valuable time and water during your winterization process.

      Rated 5 out of 5 by from One way valve. This valve works very simply. I have been using it for several years. Just ordered my second one.

      Rated 5 out of 5 by from Still Works great 5 years in! Purchased two of these 5 years ago. Both fit perfectly and make blowing out the lines a simple task. Never once had a leaking issue or functional issues with these. I clean them off nicely before each years installation and gently coat the rubber parts with pool lube just to be sure. Have them in my hand ready to install for a 6th closing, very impressed with this purchase!

      Rated 3 out of 5 by from Will soon see how good it is Replaced eyeball with this and had lack of suction at the skimmer. Will only install to winterize this weekend and hope it works to avoid draining pool.

      Rated 1 out of 5 by from Won't hold water back Bought 2 of these for my 2 outlets... Got everything closed up and they will not hold the water back.. I have a steady stream coming though I have to get the pool guy back to undo the cover and pump water off the cover just to get to the plugs and exchange them for solid plugs so I don't loose all my water all winter long ...not only wasted my money on the plugs but spending another 100 or so to get them changed...

      Rated 5 out of 5 by from Super impressed with this product After years of struggling to get the water blown out of the return lines in my in ground, often by myself requiring all kinds of rigs to hold the blower secure while I tried to get the plugs in before too much backflow into the lines, I came across this product. Its like having another person available to help, without having to actually find another person to help when you are ready to close the pool. I have used them for several years and boy has it saved me hours and hours of time and trouble. I used to dread closing the pool and worry all winter if the lines actually had been blown clear enough to avoid freezing and cracking something. There ARE caps that snap on after you are done using the one way valve to blow out the lines too, to prevent water or ice pressure from seeping back into them over the winter months. Somehow I neglected to put them on last year and one of the valves got damaged but still didn't let water into the lines and fittings themselves, so I'm back to buy another. It was my fault, though, not failure of the valve itself in any way. I cannot begin to tell you how happy I am with this product. Yes, it does work and yes, I never want to have to close my pool again without them!
