Burst pipes frozen Cardiff thaw safely

Winter Frozen pipes are an everyday issue in Cardiff particularly when it suddenly snaps to cold. When water in your pipes is frozen, it expands placing tremendous pressure on the walls of the pipes. This may result in cracks or even complete bursts, resulting in severe water damage to your house.

Should a pipe freeze or burst, it is important to do so in a safe and swift manner. 

The following details how to thaw frozen pipes and avoid the expensive damages.

1.Why Pipes Burst and Freeze.

Water in pipes that are exposed or which are not well insulated may be frozen when the temperature falls below freezing. It then expands as it freezes, putting pressure on the inside of the pipe. At a certain time, the pipe is not able to sustain this pressure and it bursts.

Pipes are likely to freeze in common locations, which include:

  • Lofts and attics
  • Basements
  • External walls
  • Under sinks or in cupboards.

2.Knowing these risk areas can enable you to take action when problems occur quickly.

Frozen or Burst Pipes.

  • Before taking action, it’s important to identify the issue. Look out for:
  • No water flow from taps
  • Frost visible on pipes
  • Suspicious odors out of drains.
  • Unusual noises such as banging or gurgling.
  • Stains or leakage of water (indication of a leaked pipe)

3.When you find water leaking, you might be facing a burst pipe as opposed to a freeze.

First Aid.

1. Shut off the Water Supply.

In case a pipe bursts or you think it is about to burst, find your main water valve and switch it off. This will prevent further flooding and damage.

2. Open the Taps

To alleviate pressure, turn on your taps a little to allow melted water to pass through when the pipe starts thawing.

3. Find the Frozen Section.

Attempt to locate the point of freezing of the pipe. This will typically be in the least insulated and coldest part of your home.

4.How to Thaw Frozen Pipes.

Care should be taken when thawing pipes to prevent additional damage.

  • Use Gentle Heat
  • Use: Apply gentle, regular heat to the frozen part with:
  • A hairdryer
  • Warm (not boiling) towels.
  • A space heater (distanced)

Begin at the end that is closest to the tap and head to the frozen part.

5.Never Use Open Flame.

Do not blowtorch, use lighters or open flame. These may cause damage to the pipes and cause severe fire risks.

6.Be Patient

It can take time to thaw. Quickness in the process or extremely high heat may result into cracking of the pipes.

7.What Should I do in Case the Pipe bursts?

  • In case the pipe has burst:
  • Have the water supply off.
  • Drain the system by turning on all taps
  • Turn off your heating system when you need to.
  • Contact an emergency plumber.

Professional help is crucial to repair the damage and prevent further issues.

8.How to avoid Frozen Pipes in Cardiff.

It is always possible to prevent a crisis rather than to deal with it. The following are easy measures to preserve your pipes:

  • Wrap up pipes in cold places such as garages and lofts.
  • Turn the heating to low when it is very cold.
  • Close joints and draughts around pipes.
  • Allow dripping of taps in the freezing weather.
  • Have your boiler serviced as well so that you can have efficient heating.

All these can greatly decrease chances of freezing.

10.The importance of Quick Action.

When action is not taken in good time, it can cause a lot of water damage, moulds and costly repair work. A small burst pipe can cause a lot of water to flow within a short period of time.

Quick response and safe thawing practices can help repair your plumbing system more effectively by reducing its damage and minimising the time it takes to fix it.
