How to Fix a Leaking Shower Pipe Behind the Wall

Hidden water leaks cause immeasurable damage to the house. Water leaks lead to mold accumulation behind walls which can affect the structural integrity. It also provides a warm, moist environment for household pests to grow. Shower leaking behind the wall can also lead to a high water bill putting unnecessary stress on you. These leaks are not always easy to detect but require immediate attention because they can cause immense damage to your home. Generally, the shower leaks you see have easy solutions. The leaks you cannot see are the real threat to your house, and you need plumbers in Sacramento to fix them to prevent further loss.

Here’s how to fix shower leaks behind walls.

Look for Signs

  • If you have a basement and a shower on the first floor, you might see water dripping from the ceiling onto the basement floor.
  • Water stains are one of the telltale symptoms of a leak coming from a shower valve behind the wall. It is easy to notice dried water stains on the ceiling below the shower. Behind-the-wall leaks from shower valves are generally slow. Usually, a defective valve or shoddy soldering at the valve water connection points causes these pinhole leaks.

How To Fix?

Clean the shower arm’s threads before reinstalling it with a new plumber’s tape (or replacing it if it’s cracked or rusty). Just like a bolt into a nut, the arm easily twists into the elbow. It is advisable to avoid cross-thread the connector when you start twisting. Also, do not tighten the shower arm because this could affect the pipe or elbow.

If a DIY solution seems tricky, contacting an expert for plumbing in Sacramento, CA, is the best solution.
