There was no water shut off valves under the sink! #diy #helpingothers #plumbing

What happens here

Before commencing any plumbing work, it is imperative to shut off the water supply to prevent leaks or flooding. First, locate your home's PEX manifold (if applicable). Use a PEX manifold key to turn off the water supply to the specific area where you'll be working (e.g., kitchen sink, master bath tub). The video highlights that older manifold valves might be stiff or breaking. Following this, locate the main water line coming into your house and fully shut off the main water valve. This ensures no water pressure is present in the lines you are working on.

Goal: Ensure no water flow to the work area and main house.

What they say

We're going to be using these stainless steel crimp rings and this Apollo crimp gun. Once you get your crimp, it actually has a little blue light that comes on. Let you know that it's good. I bought this little key for a mana block pecs manifold. I have to go back deep into a closet. Shut that off. It is so hard already breaking. This is the main water line coming in. You can just shut that off right there. The water's off. So you want to grab a crescent wrench or a basin wrench or some kind of wrench.
