Freezing Temperatures

When temperatures drop, water inside your pipes can freeze. As water freezes, it expands, putting immense pressure on the pipe walls. This pressure can cause pipes to crack or burst, especially in poorly insulated areas like basements or outdoor pipes.

How to Prevent Freezing Pipes:

Insulate Pipes: Wrap pipes in foam insulation, especially those in unheated areas.

Keep the Heat On: Maintain a consistent temperature in your home, even when you’re away.

Let Taps Drip: During extreme cold, allow a small trickle of water to flow through your taps to prevent freezing.

Seal Gaps: Use caulk or weatherstripping to close gaps around windows and doors where cold air can enter.

 

High Water Pressure

Excessively high water pressure can stress your pipes and lead to ruptures. While high pressure may seem like a luxury for strong water flow, it can strain pipe joints and weaken them over time.

How to Prevent High Water Pressure:

Install a Pressure Regulator: Use a pressure-reducing valve to keep water pressure within safe limits (typically 40-60 PSI).

Monitor Pressure Levels: Use a pressure gauge to check your system regularly.

Service Your Plumbing System: Have a professional plumber inspect your system for signs of pressure-related wear.

Corrosion & Ageing Pipes

Over time, pipes can corrode or weaken, especially if they are made of older materials like galvanised steel. Corrosion thins the pipe walls, making them more prone to leaks and bursts.

How to Prevent Corrosion:

 

Inspect Regularly: Look for signs of rust, discolouration, or leaks.

Replace Old Pipes: Upgrade to modern, durable materials like copper or PEX piping.

Soften Hard Water: Install a water softener if your water supply has high mineral content, which accelerates corrosion.

 

Blockages & Clogs

Clogs in your pipes can create a build-up of pressure, particularly if they’re severe enough to block the flow of water completely. This trapped pressure can cause pipes to burst.

How to Prevent Blockages:

Avoid Flushing Non-Flushables: Never flush items like wet wipes, grease, or large food scraps down the drain.

Clean Drains Regularly: Use drain cleaners or natural solutions (like baking soda and vinegar) to prevent build-up.

Install Strainers: Place strainers in sinks and showers to catch debris and hair.

 

Ground Movement & External Impact

External factors, such as ground movement, nearby construction, or accidental impact, can shift or damage pipes. This is more common for underground pipes but can also affect those within your home.

How to Prevent External Damage:

Mark Pipe Locations: Know where your underground pipes are before landscaping or digging projects.

Install Flexible Pipes: Use materials that can withstand minor shifts in the ground.

Monitor for Vibrations: Keep an eye on nearby construction projects that may cause vibrations affecting your pipes.
