Tap valves are prone to a variety of issues over time, but many of these problems can be resolved with simple repairs or part replacements. Here are some common problems you might encounter:

Leaking: A leaky tap is often caused by worn-out O-rings, washers, or a faulty cartridge. To fix this, you'll need to identify the source of the leak and replace the damaged parts.

Low Water Pressure: If your tap has reduced water flow, the aerator or cartridge may be clogged with mineral deposits. Cleaning or replacing these components can help restore normal water pressure.

Difficulty Turning the Handle: This could be due to a worn-out stem or damaged handle. Lubricating the stem or replacing the handle can make it easier to turn.

Temperature Fluctuations: Inconsistent water temperature can be a sign of a faulty cartridge or improper installation. Adjusting or replacing the cartridge may solve this problem.

Noise or Vibrations: Unusual noises or vibrations when using the tap can indicate loose parts or water hammer. Tightening loose fittings or installing a water hammer arrestor can help resolve these issues.

By understanding these common problems and their solutions, you can maintain your tap valve parts more effectively and avoid the need for costly repairs or replacements.
