A leaking shower can cause water damage to surrounding areas, increase water bills, and create the risk of mold or mildew growth. Identifying and fixing the source of the leak promptly ensures the shower operates efficiently and prevents further damage.
Common Causes of Shower Leaks
1. Showerhead Leaks:
• Worn-out gaskets or loose connections can cause water to drip from the showerhead.
2. Leaking Faucet or Valve:
• Faulty washers, O-rings, or cartridges in the faucet or valve can result in a continuous leak.
3. Grout and Sealant Issues:
• Cracked or missing grout and degraded caulking can allow water to seep behind tiles or into walls.
4. Drain Leaks:
• A loose or damaged drain assembly can cause water to leak under the shower.
5. Plumbing Line Leaks:
• Leaks in the water supply or drain pipes behind walls or under the floor can lead to hidden water damage.
