Before You Start

  • Turn off the water at the isolation valve (or mains) before dismantling fittings.
  • Protect the area with a towel and keep a bucket handy.
  • Know your limits: If you can’t access pipework safely or you suspect a major leak, stop.
  • Useful basics: adjustable spanner, screwdrivers, plunger, PTFE tape, cloth, small drain snake.

The Top 10 DIY Plumbing Fixes

1) Fix a Dripping Tap

Cause: worn washer/O-ring or cartridge.

  1. Turn off isolation valve.
  2. Remove handle and cover plate.
  3. Replace washer/O-ring (or cartridge for mixer taps).
  4. Reassemble and test.

2) Unclog a Sink Drain

Cause: grease, food, hair, soap residue.

  1. Plunge firmly for 20–30 seconds.
  2. Use baking soda + vinegar, wait 15 minutes, flush hot water.
  3. Use a drain snake for stubborn clogs.

3) Clear a Blocked Toilet

Cause: too much paper or non-flushables.

  1. Use a flange plunger with a tight seal.
  2. Try a toilet auger if plunging fails.
  3. Avoid harsh chemicals that can damage seals.

4) Tighten a Loose Tap

Cause: mounting nut loosens under the sink.

  1. Turn off water as a precaution.
  2. Locate the fixing nut beneath the basin.
  3. Tighten carefully; realign before fully securing.

5) Replace or Descale a Showerhead

Cause: limescale blocks nozzles.

  1. Unscrew showerhead (use cloth to protect finish).
  2. Soak in vinegar 30–60 minutes, scrub and rinse.
  3. Refit with PTFE tape if needed, test for leaks.

6) Fix a Running Toilet

Cause: flapper not sealing or float too high.

  1. Check flapper for wear; replace if warped.
  2. Adjust float to lower water level.
  3. Ensure chain has slight slack (not too tight).

7) Clean a Clogged Aerator

Cause: mineral deposits reduce flow.

  1. Unscrew aerator from tap spout.
  2. Soak in vinegar for 20–30 minutes.
  3. Brush, rinse, refit, and test flow.

8) Patch a Small Pipe Leak (Temporary)

Note: Use as a short-term fix only.

  1. Turn off water and dry the pipe.
  2. Wrap with self-amalgamating tape or a repair clamp.
  3. Turn water on slowly and check for seepage.

9) Improve Low Pressure (Single Fixture)

Cause: aerator clog or partially closed valve.

  1. Clean aerator (see #7).
  2. Check isolation valve is fully open.
  3. Flush tap for 30 seconds after cleaning.

10) Insulate Exposed Pipes

Why: helps prevent freezing and bursts in winter.

  1. Measure pipe length/diameter.
  2. Fit foam sleeves and secure joins with tape.
  3. Cover bends and gaps—no exposed sections.

When to Call Citywide Plumbers

DIY is great for minor issues, but some problems need professional tools and experience. Call a plumber if you notice repeated blockages, water stains on ceilings/walls, damp patches, sewage smells, or any leak you can’t isolate quickly. Also stop immediately if you suspect gas-related issues or you’re unsure what you’re looking at.

Preventative Plumbing Maintenance Tips

  • Inspect monthly: check under sinks, around toilets, and visible pipe joints for drips.
  • Protect drains: use strainers, avoid pouring grease down sinks.
  • Descale regularly: clean aerators and showerheads to keep flow steady.
  • Watch your bills: sudden spikes can signal hidden leaks.
