Conducting a winter leak inspection

As colder weather sets in, it becomes crucial for businesses to protect their water systems from leaks and damage. Conducting a thorough winter leak inspection can help prevent costly repairs, reduce water waste, and keep operations running smoothly. Winter brings unique challenges to plumbing systems, and by prioritising leak inspection, you can safeguard your business and improve water efficiency.

Why winter leak inspections matter

During winter, colder temperatures put added strain on pipes, joints, and fittings. Water in exposed pipes can freeze, expanding and increasing the risk of cracks or bursts that may lead to leaks. Even small, undetected leaks can lead to extensive water waste and higher bills if left unchecked. Regular leak inspections ensure that minor issues are addressed before they escalate into larger, costlier repairs.

How to carry out a comprehensive winter leak inspection

Inspect outdoor fixtures:

Start by checking outdoor taps, hose bibs, and irrigation systems. Ensure they’re fully drained and disconnected to avoid freezing damage. Look closely at downpipes and other drainage points, which may channel melting snow and rain towards your plumbing.

Examine indoor plumbing for signs of leaks:

Indoors, carefully inspect exposed pipes for any signs of condensation or "sweating," which can indicate slow leaks or condensation from temperature changes. Pay particular attention to basements, garages, and crawl spaces where pipes are often exposed to colder temperatures and can freeze if unprotected.

Conduct a water meter test for hidden leaks:

A water meter test can help you detect hidden leaks that may otherwise go unnoticed. First, turn off all water-using devices and check the meter reading. After about an hour, check the reading again; any change could indicate an undetected leak in your system.

Inspect toilets and taps for silent leaks:

Toilets and taps are common sources of “silent” leaks. For toilets, add a few drops of food colouring to the cistern; if colour appears in the bowl without flushing, there’s a leak that needs fixing. Dripping taps should also be checked and repaired as necessary, as they contribute significantly to water waste.

Key areas of vulnerability to monitor

Winter weather can have severe effects on specific areas of your plumbing, making them vulnerable to leaks and damage. For example, pipes in unheated areas are especially prone to freezing and bursting if not insulated. Outdoor taps and hose bibs should also be checked, as water left in these fixtures can freeze, expand, and cause fractures. You can find out more about preventing pipes from freezing here .

The water heater is another area to monitor closely. During colder months, water heaters work harder to maintain temperature, increasing the likelihood of leaks or performance issues. Finally, check cellar or underground walls and floors for signs of moisture, as cracks in the foundation can allow water to seep in.

Preventative measures to enhance winter leak protection

After completing your inspection, consider taking preventative steps to safeguard your plumbing for the rest of winter. Insulate exposed pipes, especially in unheated areas, to prevent freezing and potential leaks. Seal any visible cracks in walls or foundations to protect against moisture intrusion, and make sure hoses and outdoor taps are disconnected and covered.

If your business premises will be vacant over winter holidays, set thermostats to around 10°C to keep pipes from freezing while minimising energy costs. Regular maintenance and inspections throughout winter can further reduce the likelihood of damage and leaks.

Acting quickly to address any discovered leaks

If you identify a leak during your inspection, taking prompt action can minimise water damage and repair costs. For significant leaks, shut off the main water supply to prevent further water loss and call a licensed professional to handle repairs. Make sure you document any leaks or damage you find, as this may be helpful for insurance claims if necessary.

Embracing leak detection for a more efficient business
