Plumbing issues can strike at the most inconvenient times, whether it’s a leaking tap or a burst pipe. Left unchecked, even minor problems can turn into costly repairs and cause significant disruption in your home. Being aware of common plumbing issues – and addressing them promptly – can save both time and money.
At Piran Plumbing in Penzance, our team of qualified engineers has been helping homeowners across West Cornwall for nearly two decades. From Lelant to Land’s End and everywhere in between, we’re proud to serve the community from our conveniently located new base on the Long Rock Industrial Estate.
In this guide, we outline the 7 most common plumbing problems to watch for this season and provide practical tips on how to prevent them.
1. Dripping Taps
A dripping tap is more than just an annoying sound – it’s a common issue that wastes water and increases your bills. Even a slow drip can waste hundreds of litres over time. Drips are usually caused by worn washers or seals, but sometimes they indicate a larger problem with your plumbing system.
Tip: Check taps regularly and have leaks repaired promptly. Our engineers can quickly diagnose the cause and fix it before it turns into a bigger issue.

2. Running Toilets
A toilet that keeps running may seem minor, but it can significantly increase your water usage. This problem is usually caused by a worn flapper, faulty valve, or misaligned float. Running toilets not only waste water but can also signal underlying issues with your plumbing system.
Tip: Listen for continuous flushing or hissing sounds, and don’t wait to get it fixed.
Let Piran Plumbing take care of it – our local team can repair running toilets quickly, saving you water and money.
3. Low Water Pressure
Low water pressure affects showers, taps, and even appliances like washing machines. It can result from leaks, blocked pipes, or issues with the water supply system. If left unchecked, it can also put extra strain on your appliances, reducing their lifespan.
Tip: Check water pressure across different taps and fixtures. Early detection helps prevent more serious issues.

4. Pipe Leaks and Corrosion
Hidden leaks behind walls or under floors can cause serious water damage over time. Corrosion in older pipes may lead to leaks or burst pipes, especially during seasonal temperature changes. Early detection is critical to prevent costly repairs and property damage.
Tip: Keep an eye out for damp patches, unusual water bills, or unusual noises from your plumbing system.
Our team at Piran Plumbing can identify hidden leaks and repair or replace affected pipework quickly and reliably.

5. Water Heater and Cylinder Issues
Hot water problems are common as temperatures drop. Water heaters and cylinders may develop leaks, sediment build-up, or inefficient heating. While not every issue requires a boiler service, maintaining your water heating system is essential for comfort and efficiency.
Tip: Check for signs like inconsistent water temperature, strange noises, or leaks around your cylinder or pipes.
If you notice issues, book a call with Piran Plumbing – our engineers can troubleshoot and restore your hot water system efficiently.
7. Seasonal Pipe Freezing
As the weather cools, pipes that are exposed or poorly insulated may freeze, especially in older homes. Frozen pipes can burst and cause significant damage to your property. Preventive measures are far easier and cheaper than emergency repairs.
Tip: Insulate vulnerable pipes and let taps drip slightly during extremely cold nights to prevent freezing.
