Plumbing issues are something every homeowner in Cardiff and Caerphilly will face at some point. While some problems are minor and can be fixed quickly, others may require the help of a qualified local plumber. In this article, we’ll cover the 7 most common plumbing problems in South Wales homes, how to spot them early, and when to call in the experts.

Bathroom in Cardiff

1. Leaky Taps and Dripping Fixtures

  • Wasting water, increasing bills, and causing annoying drips.

  • Often caused by worn washers or faulty cartridges.

  • DIY tip: Turn off the water, replace the washer.

  • When to call us: If the tap continues to drip, or you’re unsure about dismantling it.

2. Blocked Drains

  • Slow draining sinks or unpleasant smells are early signs.

  • Food, grease, hair, and soap are the usual culprits.

  • DIY tip: Use a plunger or eco-friendly drain cleaner.

  • When to call us: If water backs up or blockages keep returning — we provide full drainage services in Cardiff.

3. Low Water Pressure

  • Weak flow from taps and showers is common in older Cardiff homes.

  • Could be caused by pipe corrosion, leaks, or faulty valves.

  • Solution: A plumber can diagnose the cause and restore normal pressure.

4. Boiler Breakdowns & Heating Issues

  • Cold radiators, strange noises, or no hot water are all warning signs.

  • Boilers should be serviced annually by a Gas Safe engineer.

  • Cardiff & Caerphilly Plumbers handle boiler repairs, servicing, and installations.

5. Running Toilets

  • A constantly running toilet can waste hundreds of liters of water a day.

  • Usually caused by a faulty flapper or fill valve.

  • DIY fix: Sometimes an adjustment works, but parts often need replacing.

6. Burst or Leaking Pipes

  • Common in winter due to freezing temperatures.

  • Can cause serious water damage if not addressed quickly.

  • Emergency plumbers in Cardiff are available 24/7 to handle pipe bursts.

7. Outdoor Plumbing Problems

  • Garden taps, outside pipes, and drainage systems often get overlooked.

  • Leaks or clogs can cause flooding in heavy Welsh rain.

  • Tip: Insulate outside taps in winter and check them regularly.
