Plumbing problems are something every homeowner dreads — they’re inconvenient, sometimes costly, and can lead to serious damage if ignored. Whether it’s a dripping tap or a burst pipe, catching the issue early is crucial. In this guide, we’ll cover 10 of the most common plumbing issues in UK homes and how you can prevent them from becoming a major headache.
1. Dripping Taps
Dripping taps are more than just annoying — they waste water and increase your bill over time. A worn washer or faulty valve is often the culprit.
Prevention Tip: Turn taps off gently and replace washers as soon as you notice wear. Investing in modern mixer taps with ceramic discs can also reduce wear and tear.
2. Blocked Drains
Bathroom and kitchen drains often become clogged with hair, grease, soap scum, and food particles. Left unchecked, blockages can lead to foul smells and even pipe damage.
Prevention Tip: Use drain covers to catch hair and food debris, and avoid pouring fats or oils down the sink. Regularly clean your plugholes with boiling water and baking soda.
3. Low Water Pressure
If your shower has gone from a powerful stream to a disappointing trickle, low water pressure could be the issue. It’s often caused by a build-up of sediment in the pipes or problems with the main supply.
Prevention Tip: Clean or replace aerators and showerheads regularly. If pressure remains low, a plumber can inspect for deeper blockages or valve issues.
4. Leaky Pipes
Pipe leaks can be hidden behind walls or under floors, making them difficult to detect until damage is done.
Prevention Tip: Keep an eye on your water bill for sudden increases. Look for damp patches or mould around walls and ceilings. An annual plumbing inspection can help catch leaks early.
5. Running Toilets
A constantly running toilet can waste hundreds of litres of water per day, often caused by a faulty flapper or float.
Prevention Tip: Check the toilet tank components every six months. Replacing a flapper or adjusting the float is usually a simple DIY fix.
6. Boiler Issues
Your boiler is the heart of your heating system. Common problems include loss of pressure, kettling, or no heat at all.
Prevention Tip: Have your boiler serviced annually by a Gas Safe registered engineer. This ensures it’s running efficiently and safely. You can find more info on Gas Safe Register — the UK’s official gas safety body.
7. Slow Draining Sinks
If your sink takes forever to empty, a partial blockage is likely forming. Ignoring it can lead to a complete blockage and foul smells.
Prevention Tip: Avoid rinsing coffee grounds, oil, and food waste down the sink. Try a monthly treatment with vinegar and baking soda followed by hot water.
8. Burst Pipes
Burst pipes are most common in winter when freezing temperatures cause water to expand inside the pipes. This can lead to flooding and expensive repairs.
Prevention Tip: Insulate exposed pipes, especially in lofts or external walls. During a cold snap, keep your heating on low even if you’re away.
9. Noisy Pipes (Water Hammer)
That loud banging noise from your pipes is known as “water hammer.” It’s caused by a sudden stop in water flow, usually from faulty valves or high water pressure.
Prevention Tip: Install water hammer arrestors and have your water pressure checked by a plumber if you notice frequent banging sounds.
10. Sewer System Backup
This is one of the messiest plumbing disasters. If multiple drains are blocked or you smell sewage, your main sewer line might be clogged.
Prevention Tip: Don’t flush wipes, nappies, or sanitary products. If you have large trees near your home, root intrusion could also be the issue — regular drain inspections can help catch it early.
