Common Plumbing Problems in Swindon

Every home in Swindon will experience plumbing problems at some point. From dripping taps to blocked drains, knowing what to look for and when to call a professional can save you money and prevent water damage.

Dripping taps and running toilets

Why taps drip

A dripping tap is almost always caused by a worn washer or ceramic cartridge inside the tap mechanism. It's one of the simplest plumbing repairs but one of the most commonly ignored. A single dripping tap wastes approximately 5,500 litres of water per year. On a water meter in Swindon, that's roughly £15-£20 added to your annual bill, plus the irritation of the constant drip. Fixing a dripping tap typically costs £50-£120 and takes under an hour.

Running toilets

If your toilet keeps running after flushing, the most common cause is a worn flush valve or fill valve inside the cistern. You can test this by lifting the float arm. If the water stops, the fill valve needs adjusting or replacing. If it continues, the flush valve seal is worn. This is a straightforward repair costing £60-£150 in Swindon and prevents hundreds of litres of wasted water per day.

Blocked drains and slow-running water

Kitchen sink blockages

Kitchen sinks in Swindon homes most commonly block due to fat and grease buildup. Despite what the packaging says, washing up liquid doesn't dissolve fat once it enters your pipes. It solidifies on the cold pipe walls and gradually narrows the flow. Prevention: wipe greasy pans with kitchen paper before washing. Never pour cooking oil down the sink. If your kitchen sink is already slow, try a plunger first. If that doesn't work, professional drain clearance costs £50-£120.

Bathroom blockages

Bathroom sinks and shower trays typically block due to hair and soap scum. A simple hair trap over your plughole (£2-£5 from any hardware shop) prevents most bathroom drain blockages. Toilets block when people flush wet wipes, cotton buds, or sanitary products. Even 'flushable' wipes don't break down like toilet paper. In Swindon, we clear dozens of toilet blockages caused by wet wipes every month.

External drain problems

If multiple fixtures are draining slowly, the problem is likely in your external drainage. Common causes in Swindon include tree root ingress, ground settlement cracking pipes, and years of fat buildup. A CCTV drain survey (£90-£350) can identify the exact problem without any digging.

Low water pressure and noisy pipes

Causes of low water pressure

Low water pressure in Swindon can be caused by several things. If it's affecting the whole house, check with your neighbours. If they have the same problem, it's a supply issue and you should contact your water company. If it's only your property, common causes include a partially closed stopcock, a leak on the supply pipe, corroded internal pipework, or a faulty pressure reducing valve. If pressure has dropped suddenly, a burst pipe is the most likely cause.

Banging and hammering pipes

Water hammer is that banging noise you hear when you turn a tap off quickly. It's caused by the sudden stoppage of water flow creating a shockwave in the pipes. While annoying, it can also damage pipe joints over time. Fitting a water hammer arrestor (a small device fitted near the tap) usually solves the problem. If you hear continuous knocking when the heating is on, it could be pipework that needs better securing or a pump issue.

When to call a plumber in Swindon

DIY vs professional

Some plumbing jobs are safe to tackle yourself: changing a tap washer, plunging a blocked sink, or bleeding a radiator. However, anything involving gas, mains water supply, or waste pipes that run under floors or through walls should be left to a qualified plumber. In Swindon, we regularly fix bodged DIY plumbing that has caused more damage than the original problem. A botched pipe joint behind a wall can leak for weeks before you notice.

Finding a reliable plumber in Swindon

Look for qualifications (City & Guilds, NVQ in plumbing), insurance (public liability of at least £2 million), and membership of a trade body. Ask for references and check online reviews. A good plumber will give you a clear quote, explain the work, and not pressure you into decisions. Our Swindon engineers are fully qualified, fully insured, and provide upfront pricing.
