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.
- Turn off isolation valve.
- Remove handle and cover plate.
- Replace washer/O-ring (or cartridge for mixer taps).
- Reassemble and test.
2) Unclog a Sink Drain
Cause: grease, food, hair, soap residue.
- Plunge firmly for 20–30 seconds.
- Use baking soda + vinegar, wait 15 minutes, flush hot water.
- Use a drain snake for stubborn clogs.
3) Clear a Blocked Toilet
Cause: too much paper or non-flushables.
- Use a flange plunger with a tight seal.
- Try a toilet auger if plunging fails.
- Avoid harsh chemicals that can damage seals.
4) Tighten a Loose Tap
Cause: mounting nut loosens under the sink.
- Turn off water as a precaution.
- Locate the fixing nut beneath the basin.
- Tighten carefully; realign before fully securing.
5) Replace or Descale a Showerhead
Cause: limescale blocks nozzles.
- Unscrew showerhead (use cloth to protect finish).
- Soak in vinegar 30–60 minutes, scrub and rinse.
- Refit with PTFE tape if needed, test for leaks.
6) Fix a Running Toilet
Cause: flapper not sealing or float too high.
- Check flapper for wear; replace if warped.
- Adjust float to lower water level.
- Ensure chain has slight slack (not too tight).
7) Clean a Clogged Aerator
Cause: mineral deposits reduce flow.
- Unscrew aerator from tap spout.
- Soak in vinegar for 20–30 minutes.
- Brush, rinse, refit, and test flow.
8) Patch a Small Pipe Leak (Temporary)
Note: Use as a short-term fix only.
- Turn off water and dry the pipe.
- Wrap with self-amalgamating tape or a repair clamp.
- Turn water on slowly and check for seepage.
9) Improve Low Pressure (Single Fixture)
Cause: aerator clog or partially closed valve.
- Clean aerator (see #7).
- Check isolation valve is fully open.
- Flush tap for 30 seconds after cleaning.
10) Insulate Exposed Pipes
Why: helps prevent freezing and bursts in winter.
- Measure pipe length/diameter.
- Fit foam sleeves and secure joins with tape.
- Cover bends and gaps—no exposed sections.

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.
