I visited our local Lowes store today and an could not locate "Water Whiz flexible pvc". I did see 3/4 flex tubing, but it did not list it as pvc and it seemed a little thin. They have 50’, 100’ and even 400’ rolls. I tried 3/4 schedule 40 fittings on the end of the flex tubing for comparison and the coupling was too big.

What are the specs…Inside and outside dia, pressure ratings, etc.?

Thanks!
