Here is some of the TigerFlex running to my skimmer and low drain. Since I drain it and put it away in the fall, in the basement, I have no problem leaving it on the ground. While I've re-plumbed a few times, this TF came with the pool 12 years ago and is still good. You can see the quick-connect/ball valves at the low drain and skimmer, though the handle on the low drain ball valve is gone. Since I'm rebuilding the pool this winter those ball valves will be replaced, but the TF won't be. It works exactly like hard PVC, just a little harder to cut evenly.

Unfortunately, too many pool installer treat TF like it's hose. It's not. So they put barbed fittings INSIDE the TF with hose clamps...and it inevitably leaks. (the orig installers did that and I had to replace all the barbed fittings because it leaked just after they drove away!) But if you use glue-on Schedule 40 fittings, just like hard PVC, it doesn't leak. I've NEVER had a leak from the Sch 40 on the TF.
On caveat: You cannot bury TigerFlex, unlike hard PVC or the black flexible plastic pipe used for sprinkler systems and wells.
