Where to get Flex PVC in vancouver area?

[Rogue951]

So I've heard of it.... where can I get it in Van?
What is it called?

I'm trying to plumb in a frag tank into my system and because of the way my set up is it's easier to use something flexible than to make solid pvc angles.
I did find a short bend length at Home Depot with unions already glued to the end but it's bloody expensive and although it would cover my needs I'd rather just make the whole connection flexible.
