there's a really great 2 part epoxy i've used to fix hoses, and it has lasted a long time. I got it at home despot, one side is baby blue, and the hardener is yellow. On the hose i slapped some on, then wrapped it with black plastic from a trash bag, and a couple zip ties, it lasted at least two seasons till we sold the pool. last fall I used the same stuff to fasten the end on my vac hose for our new IG pool, after cutting out a split near the end. This stuff stays flexible, and I've had great luck with it.
