OrbitWaterMaster Underground 37112 Multi-Flex Riser, 1/2-Inch by 6-Inch

In southern california, i used a few of these in my yard where they were above-ground and exposed to daylight. After about 2 years, all started to crack and leak. I didn't expect such poor performance from an outdoor sprinkler pipe! Perhaps they'd work better underground? Regardless, I do not recommend.

This type of plastic doesn't generally age or weather well, I'm still using it but not on anything production/ mission critical

These are not flexible at all. If you bend them, they literally break in two. This is no improvement over a piece of PVC.

Good quality

Works fine
