Most plumbing problems fall into a small handful of categories, and most of them give you warning signs before they become something worse. A dripping tap rarely stays a dripping tap for long if it is ignored, and a slow drain today is often a blocked one next week. Here is what usually causes the most common plumbing issues in Cheshire homes, what you can reasonably deal with yourself, and when it genuinely is time to call in a plumber.

Dripping or Leaking Taps

A dripping tap is almost always down to a worn washer or a failing cartridge inside the tap itself, caused by ordinary wear from repeated use over the years. It sounds minor, but a single dripping tap can waste a genuinely significant amount of water over a year, and the constant drip often ends up staining the sink or bath beneath it. On older tap designs with a traditional washer, this is a straightforward and inexpensive fix. Modern mixer taps generally use a ceramic disc cartridge instead, which cannot be repaired in the same way and typically needs replacing as a whole unit when it starts to fail.

Blocked or Slow-Draining Sinks

Kitchen sinks usually block from a build-up of fat, oil and food debris that solidifies inside the pipe over time, while bathroom sinks are more commonly affected by hair, soap residue and toothpaste. A slow drain rather than a fully blocked one is often the first sign, and is worth acting on before it becomes a complete blockage. Avoid pouring fat or oil down a kitchen sink, since this is one of the most common causes of both individual blockages and wider drain problems further down the line. If a plunger or a drain rod does not clear it, a persistent blockage can point to a problem further along the pipe run rather than at the plughole itself, which is where it becomes a job for a plumber rather than a DIY fix.

Running or Blocked Toilets

A toilet that keeps running after flushing is usually caused by a worn flapper valve or an issue with the fill valve inside the cistern, letting water continuously trickle into the bowl. Left unaddressed, this can noticeably increase your water bill even though nothing looks obviously wrong from the outside. A blocked toilet, on the other hand, is almost always down to either too much toilet paper at once or something flushed that should not have been, since modern low-flow toilets use less water per flush and have less margin for error than older designs. A plunger will clear the majority of blockages. If it does not, and especially if multiple toilets or drains in the house are affected at once, this points to a blockage further down the shared drainage system rather than the toilet itself.

Leaking Pipes and Joints

A leaking pipe can range from a barely noticeable damp patch to a genuine emergency, and where the leak sits actually determines who is responsible for it. According to Citizens Advice, homeowners are responsible for all pipework within the property boundary from the stopcock inwards, while anything before that point is generally the water company’s responsibility. In practice, this means a leak under your kitchen sink or behind a bathroom wall is yours to sort, while a leak in the supply pipe out towards the street may not be.

Inside the home, leaking joints are often caused by a failed seal, a loose compression fitting, or corrosion on older pipework, particularly in properties with original plumbing that has never been updated. A small leak rarely stays small, since the ongoing moisture can lead to damp, mould and, in the case of joists or floorboards, structural damage if it goes unnoticed for long enough.

Noisy Pipework

A loud bang when a tap is turned off, often called water hammer, happens when moving water is stopped suddenly and the resulting pressure wave hits the pipework. It is more common in homes with high water pressure or older pipework that is not properly secured, and while it is not usually dangerous in the short term, the repeated impact can loosen joints and shorten the life of your pipework over time. A persistent whistling or humming sound, by contrast, more often points to a partially closed valve or a worn washer somewhere in the system restricting the flow of water.

How to Turn Off Your Water in an Emergency

If you have a significant leak or a burst pipe, knowing how to shut off your water supply quickly can make a real difference to how much damage occurs before help arrives.

Locate your internal stopcock, usually found under the kitchen sink, in a downstairs cupboard, or near where the water supply enters the property
Turn it clockwise firmly to shut off the water supply to the whole property
Open the lowest tap in the house to drain any remaining water from the pipes and relieve pressure
If the leak is near an electrical fitting or socket, turn off the electricity at the consumer unit as well if it is safe to do so
Once the water is off, call a plumber rather than attempting a permanent repair yourself, particularly for anything involving copper pipework or existing fittings

It is worth finding your stopcock now, before you ever need it in an emergency. Trying to locate it for the first time while water is actively leaking is a genuinely stressful way to learn where it is.

When to Call a Plumber

Plenty of minor plumbing issues are safe to leave for a scheduled visit. Others are worth treating as urgent. It is time to call a plumber, rather than waiting, if:

A pipe has burst or is leaking significantly
You have no water at all, or a sudden and unexplained drop in pressure
A blockage affects multiple sinks, toilets or drains at the same time
You notice damp, staining or a musty smell without an obvious visible source
A repair involves anything beyond a simple washer or fitting replacement, particularly older pipework

When choosing a plumber, it is worth checking they are listed with the WaterSafe Register, the UK’s national accreditation scheme for qualified plumbers. Unlike gas work, there is no single legal licence required to carry out general plumbing in the UK, which makes an independent accreditation like WaterSafe a genuinely useful way to check who you are hiring before they start.

It is also worth noting that not every heating-related issue is actually a plumbing problem. If your radiators are not heating properly, that is more likely a central heating fault than anything to do with your plumbing, and our guide to radiators not heating up properly covers that separately. Similarly, if it is specifically your boiler’s pressure gauge dropping rather than your household water pressure, that points to the heating system rather than your plumbing, and is covered in our guide to boilers losing pressure.
