Drains wtih Poly
I am running 1" poly in my yard and was told by a contractor that drain valves were not needed. Their basis, I beleive, was based upon:
1. Running poly and poly will flex if any residual water is left
2. I am running off of a secondary water supply which is typically turned off on October 15th.
3. My lines are about 8" - 12" deep.
What are your thoughts... I plan on installing the lines this weekend.
