I read many reviews on these intex pumps, and the problem that seems to plague them is a cheaply made plastic impeller that moves (pumps) the water. So listen up folks... if you buy a replacement pump, or even buy a pool set for the first time, BEFORE you even use the pump for the first time, take it apart until you can remove the impeller. This is pretty simple requiring only about 4 or 5 screws be removed... just make sure you pay attention to how it comes apart (especially the washers around the impeller). Then go down to walmart, home depot, lowes, or any autoparts store and buy some EPOXY. This should be two different liquids (or gels) that come in two different tubes that you must mix together. This stuff is SUPER STRONG, and most are rated for 2,500 to 3,500 lbs per square inch of strength... like steel almost. So what your going to do is get a small paint brush, and "paint" the impeller with epoxy, making a SUPER STRONG coat over the cheap plastic. Just make sure you don't get any on the inside of the hole in the center of the impeller where it slides onto the metal rod. Allow it 24 hours to dry (depending on what type of epoxy you use), and then reassemble the pump. I guarantee this will save you money and headaches in the long run. Also if any other plastic parts break on the pump, you can use this epoxy to fix/repair/strengthen them as well.
