there is blue spa flex, I don't know where to get it though, Dean? any links for blue spa flex?cali_reef said:The gray PVC pipes and fitting are SCH80 stuff, much heavier duty than white PVC. Lowes here on LI does have some limited gray stuff but I can never find the right piece . SAVKO.com carries those HD SCH80 true union valves.
The blue pipe in the picture looks like blue tape over spaflex, never seen blue spa flex before.
