This is the plumbing scenario nobody wants to deal with: turning on a water faucet and finding nothing comes out, and then finding out this is true all over the house. Usually, this comes as a morning surprise when you step into the shower, and it’s about as bad a way to start your day as you can come across.
What can you do in cases like this? We’ve already offered one suggestion, which is to try other taps around the house to see if it is indeed a problem with the whole plumbing. Once you know it’s a broad issue, we recommend taking the following steps. (If it’s only at one tap, you’ll still need to find out what’s wrong and have it fixed, but it may not be an emergency.)
