I have an Intex Sand Filter and I need to replace the to electric cord. The GFCI end on the cord leaks and is no longer waterproof so sometimes it gets water in it and will not work unless I open it up and let it dry out. The cord says "Caution - Replace only with cord set number SJTW". I looked on Intex's website and could not find a replacement cord so I need help finding the correct cord for my pump. Anyone got any suggestions?
