My immediate thought is PVC expands quite a bit. If it is exposed to the sun check to make sure it has room to expand without binding. Also the UV from the sun will damage the pipe over the years. You may want to paint it or somehow protect it.


PVC (plumbing) is not rated for sunlight exposure and needs to be painted or otherwise shielded from sunlight. PVC (electrical) is not rated for plumbing/pressure use, but is UV resistant. So, if you have unprotected PVC pipe in the sun, expect more problems. And paint it, though already-damaged sections may still fail after painting due to existing damage....


It has not been winterized properly. Enersol FAQs have some great tips regarding "removable end-caps on the roof" that need to be opened. EnerSol FAQs
