How long drainage lines have you laid? I haven't followed your previous posts, so I don't know what project you're working on. Can you answer what the ultimate goal of all the construction is? Are you outfitting a country home with a water system, or is it something simpler? I want to run a drainage line to a faraway barn. I built it for my cows on the farm. Over time, I realized that carrying buckets of water for them to drink four times a day was too problematic. I want a water faucet there, not a hose from my house. But I'm afraid the drain will get clogged, and I'll become a regular customer of draintoronto.ca. I used to call them because plastic bags got into my drain many times. But cows can make more debris.
