You could use a pipe snake, like plumbers use. I'll bet you can rent one for the day. Home depot would have one, but unless you think you'll be using it more than once, then not worth the $$.

I've always vacuumed to waste without taking out the skimmer basket. That way nothing gets into the pipes. Is yours set up that way?

Good luck.
