I'm sure the mods will delete this post if I'm out of line asking a plumbing question, but since many HVAC pro's also work for companies that do plumbing I thought maybe I could get some advice.
I'm going to be taking a vacation in a few weeks. My home has that awful polybuetylene piping and is about 15 years old - right about the time when those pipes tend to start failing. In fact some homes in my neighborhood have begun failing in the last few years. Anyway, I'm wondering if I should turn off the water before I depart. I'm concerned that allowing the lines to dry out while I'm gone might actually be prone to causing damage after I return. Or should I ALMOST turn off the water, allowing just enough to remain pressurized, or just take my chances and leave the water on?
What would you guys do??
