What Causes of Burst Pipes

#Burst Pipes

Plumbing pipes are integral to the structure of your home and ensure proper water circulation, but they’re taken for granted until there’s a burst.

These pipes run through your whole property, incurring enough wear and tear until the water pressure builds up significantly, causing the pipes to burst. Such plumbing issues are very common in Australia, usually caused by wear and tear, misuse, hard water, freezing, clogs, etc.

Burst Pipes

And even though various reasons can lead pipes to burst, they’re comparatively easier to handle when you’ve figured out what exactly went wrong. Additionally, you can prevent such plumbing emergencies by following certain precautions to protect the pipework from the inside.

Let’s look at the causes of burst pipes and some preventative tips!

Common Causes of Burst Pipes

1. Freezing Temperatures

It’s a common misconception that frozen pipes mostly occur in temperate, cold climates, but they’re just as frequent in tropical climates. This happens when the water running down the pipes reaches a freezing temperature.

The water starts freezing in one area, and the pressure continues to build until the joints are affected - but diagnosing a frozen pipe early is quite difficult. Sprinkler pipes, unheated attics and crawl spaces, and pipes running parallel to poorly insulated walls will likely face this issue.

2. Corrosion and Rust

Since plumbing pipes are constantly exposed to sunlight and dust, they will likely corrode over time. Moreover, metal pipes can develop rust on their surface, weakening the joints, pipe seals, and even walls. This rust gradually corrodes the pipes, forming cracks that eventually rupture due to the water pressure.

Look for warping and discolouration on the pipes and rusty-coloured water coming out of your faucets - these are foolproof signs of corrosion. If you notice these signs, immediately call your local plumber to solve this issue.

3. High Water Pressure

Since water pipes can only withstand certain water pressure, excessive pressure is detrimental, leading to leaks, damage, and overflowing waste water. But you can manually check the water pressure to identify if there’s an excess of it.

Go to a local hardware store and purchase a hose bib gauge that can be easily attached to an external spigot to open the pipeline. This will help you measure the water pressure - a normal reading would range from 50 to 80 PSI (pounds per square inch). If you find that the water pressure is measuring too high, call a plumber.

4. Clogs and Blockages

Clogs or blockages inside the pipe can cause excess water pressure, backing the water into your drains and sinks. Even minimal clogs can gradually increase in size and significantly disrupt the water flow, leading to pipe cracking and bursting.

If there’s a clog you can’t resolve with standard household tools, it’s best to call a plumber to get it checked. You can also install mesh drain covers in your shower, sink and tub to prevent clogs from forming altogether.

5. Old Age, Wear and Tear

As discussed above, constant exposure to dirt, debris, and sunlight can lead to wear and tear, causing the pipes to warp and the joints to loosen. Moreover, external deterrents like invasive tree roots can significantly damage your pipes.

That’s why plumbers recommend replacing your water pipes every five to ten years to prevent the corrosion from advancing too much.

How To Prevent Burst Pipes

As always, following some preventative measures and tips can save you a lot of money and pain in the long term. They help you avoid burst pipes and other related plumbing agencies, thereby lengthening the longevity of the same:

1. Insulation

Ensure outdoor piping and taps, including overflow and drain pipes for heating, are well-insulated. Check whether any joint, tap, or bend is exposed - if there’s any, immediately insulate it. Typically, plumbers utilise insulating foam or lagging in covering the entire pipework.

2. Lagging

Pipes in the ground and unheated areas, such as basements, garages, attics, etc., must be covered with lagging.

3. Keep Water Pressure In Check

If you have a tough time manually checking the water pressure every time the pipes start acting up, install pressure-reducing valves inside the pipework. These help maintain optimal water pressure within the pipes, thus, drastically reducing the chances of them bursting.

4. Regular Inspections

Like most plumbing components, scheduling frequent inspections for your pipelines will identify cracks and breakage earlier, giving you enough time to resolve them.

5. Best Practices

  • Set your central heating at least 12 degrees Celsius or 54 degrees Fahrenheit during winter so the pipes aren’t cold enough to freeze the water.
  • If you’re leaving your home for a few days, turn off the stopcock, drain all the water from the system, and keep the heating on.

What to Do if You Have a Burst Pipe

Despite following best practices and preventative measures, sometimes you’ll just have to deal with burst pipes. And what you do in this situation is important — limit it to a minor inconvenience or escalate it to a plumbing emergency.

Moreover, not addressing burst pipes properly can severely damage your home’s insulation, electricity, and water supply. Besides having to spend a lot of money to fix severe burst pipes and damaged walls, there are high chances of an electrical fire.

Step 1

Look for the signs - damp patches on ceilings, walls, or floors, low water pressure, unusual noises, and even electrical faults. The signs are often more subtle than a torrent of water flowing out of the pipes.

Step 2

Turn off the stopcock and isolate the affected area from the water. Turn on all of the taps to remove water from the supply system.

Step 3

Remove all your belongings from the damp area and avoid touching any electrical devices, especially light switches, since there is a high chance that water might have entered the circuits.

Step 4

Don’t try resolving a burst pipe independently since it can be horribly wrong, especially due to its effect on the electrical system. Immediately call a professional when you see signs of water leaking from the pipes.

Pipe Burst Prevention

Even though they’re fairly common, burst pipes can be a real nuisance and cause significant property damage when left unresolved. In addition, they aren’t as easy to fix as leaking faucets or blocked drains and require professional aid.

However, conducting regular pipe inspections and following some preventative measures can go a long way in increasing the lifespan of the pipes.
