Common Signs of Water Leaks in Mains Water Lines
Recognising the early signs of a mains water leak can save you from extensive repairs and high water bills. Here are some common indicators that you might have a water leak in your main water line or water supply pipe:
1. Unusually High Water Bills
An unexpected rise in your water bill without increased usage often points to a hidden issue. Therefore, if your bill increases suddenly, consider checking for leaks, possibly with the help of your water supply company.
2. Damp or Mould Growth
Visible damp patches, mould, or mildew on walls, ceilings, or floors suggest a possible leak in the mains water pipe. Moreover, the presence of mould can affect indoor air quality and lead to significant water damage.
3. Low Water Pressure
A sudden drop in water pressure might indicate a leak in the main water line or a supply pipe leak. Consequently, your appliances may not function properly.
4. Sound of Running Water
Hearing water when all taps are turned off can be a sign of a hidden water leak in the main water pipe. If so, it’s important to investigate promptly, possibly by checking your water meter for continuous movement.
5. Water Stains
Stains on ceilings, walls, or floors can indicate water leaking from the main water valve or a faulty stop valve. Therefore, don’t ignore such signs.
6. Visible Cracks or Warping
Structural damage such as cracks or warping can occur from prolonged leaks in the mains water line. As a result, the integrity of your property could be compromised due to ongoing water damage.
If you notice any of these signs, it’s essential to act quickly. Early detection can, therefore, prevent costly damage and reduce water wastage, ensuring the safety and efficiency of your property’s water supply.
Our Mains Water Leak Detection Process
At North West Leaks, we utilise a comprehensive approach to locate water leaks efficiently and accurately:
