Since the timers are at the end of the chain, all the hose segments are under pressure, all the time, and sitting in the hot sun.
Last year one of my 12" segments burst while I was out of town, and the water ran for a few hours before a nice neighbor came up from the trail and turned it off for us. And I went ahead and replaced the burst segment with another of the same exact type.</stupid>
I just turned the system on again for this season, and I'm wondering if I need to replace all the hose segments with something designed for constant pressure.
For the short segments I'm seeing this product from DripWorks:

described as "8 inch spring wound hose." The "spring wound" part seems like it would do the trick.
For the 50' section that closest thing I could find was this 8-ply garden hose from Flexogen.
Or is there a better solution?
I don't want to run PVC (yet) because we're going to tear up the entire yard next year anyway. And whatever solution I use for this year needs to be removable, because when we entertain 3-4 times a year I remove that 50' section so people don't trip over it.
