Here’s how I successfully replaced the main water shut off valve for my house on the weekend (higher plumber charges) — I probably saved $500 here in the Washington DC area!!
I learned from the water company that even a licensed plumber is NOT allowed to turn off the water to my house. And the plumber can’t call to have my water shut off or turned on, only I can. So I thought, “why don’t I try to replace the valve too?”
It felt REALLY good when he turned the water on and my work didn’t leak!
