Identifying the Cause of a Leaking Shower Tap

Determining the exact cause of a leaking shower tap is crucial for effective repair. Common reasons for leaks include worn washers, damaged O-rings, corroded valve seats, and loose or faulty fittings. Begin by visually inspecting the tap for obvious signs of wear or damage, then proceed to more detailed diagnostics as necessary.

  • Worn or damaged washers: Washers are the primary sealing components that prevent water flow when the tap is off. Over time, they deteriorate, causing drips.
  • Faulty O-rings: These rubber rings seal the tap spindle and may degrade or become misaligned, resulting in leaks.
  • Corroded valve seats: The valve seat connects the tap body to the washer. Corrosion or mineral buildup here can prevent a tight seal.
  • Loose or damaged fittings: Connections within the tap assembly may loosen or break, leading to leaks.
