Detecting and repairing leaks

Identifying and addressing leaks

Detecting a water leak early can prevent costly repairs and operational disruptions. Business owners and facility managers should be aware of common signs of water leaks and take immediate action to resolve them.

1. Signs of a water leak. Water leaks can manifest in different ways, from subtle indicators to obvious damage. Recognising these warning signs early can help businesses take timely corrective measures. Some common signs include:

• Unexpected increases in water bills or consumption.
• Low water pressure in faucets and appliances.
• Visible water stains on walls, ceilings, or floors.
• Peeling paint, bubbling wallpaper, or persistent wet patches.
• Mould growth, musty odours, or a decline in indoor air quality.
• Sounds of running water when taps are off, such as hissing or gurgling noises.
• Unexplained puddles, boggy ground, or green patches in dry areas, indicating underground leaks.

2. Causes of water leaks. Understanding the common causes of leaks can help businesses take preventive measures. Some frequent sources of leaks include:

• Aging or corroded pipes.
• Faulty plumbing installations and maintenance.
• High water pressure causing stress on pipe joints.
• Blockages leading to pipe bursts.
• Damage due to extreme weather conditions.
• Leaks from HVAC systems, sprinkler systems, or faulty appliances.

3. Detecting a leak. If a business suspects a water leak, conducting a simple test using a water meter can help confirm its presence:

1. Turn off all water-using appliances and ensure no one is using water.
2. Record the meter reading.
3. Wait a few hours without using any water, then check the meter again.
4. If the reading has changed, this indicates water loss, likely due to a leak.
5. For difficult-to-detect leaks, businesses should consider professional leak detection services that use advanced tools to pinpoint the exact location of leaks.

6. Steps when a pipe bursts. Acting quickly in the event of a burst pipe can minimise damage and prevent further complications:

1. Locate and turn off the main water valve to stop the flow of water and shut off the supply.
2. Open taps to allow any remaining water to drain out the system and relieve pressure.
3. If the leak is near electrical outlets or appliances, shut off the electricity to prevent hazards.
4. Use towels, buckets, or waterproof sheeting to contain the leak and minimise water spread and damage.
5. Contact a professional leak repair service to assess and fix the issue.
6. Take photos and notes to document the damage for insurance claims, allowances and future preventive measures.

7. Responsibility. The responsibility for leaks and bursts typically depends on the location of the issue within the water supply system:

• Property owners are responsible for maintaining and repairing leaks or bursts within their premises, including internal plumbing and the pipework leading from the external stop tap to the building.
• Regular inspections are necessary to prevent damage and excessive water charges.
• Leaks or bursts occurring outside the property boundary fall under the responsibility of the water wholesaler, which maintains public water mains and infrastructure.
• If a burst pipe or major leak is detected on a public water main, businesses should report it to their water retailer, who will liaise with the wholesaler for repairs.
• Some properties, such as industrial estates or multi-tenanted buildings, have shared private pipework where responsibility is distributed among property owners.
• You may qualify for a leak allowance if your wholesaler agrees. This allowance can reduce charges caused by a leak. Wholesaler policies vary, as some cover only sewerage while others include both water and sewerage. If eligible, your retailer can submit a leak allowance request, and you can claim the allowance based on the wholesaler’s policy.
