The .. blue? Oh you mean the hose from the pump to the skimmer? That's not spaflex, that's some ribbed tubing that matches the 1-1/4" skimmer intake. The skimmer came with it, I don't know what it is or where Chin even got it from. Suppose I should ask him. Looks like vacuum hose to me, the last time I used something like that though it leaked like crazy no matter what I did with it. Hopefully this stuff doesn't.
In the picture the 2" pipe that leads to the Dart and the 1.5" pipe coming out of it is spaflex, as is the 8" section that leads to the first elbow on the skimmer feed. From a distance it looks the same as white PVC but if you see it close up you can see it's a spiral of soft white plastic PVC. It's not as flexible as clear vinyl (which you have to use hose barbs for) but it does have a fair bit of give and it just cements into regular PVC fittings using regular PVC cement. BTW at Western Pump you can get clear primer and clear cement for PVC - makes for much nicer and cleaner plumbing work than the usual purple and grey stuff.
