Hot Weather Playing Havoc With Your Drains?

As the warm summer months arrive and things begin to get hot, our home drainage system is one of the last things on our mind. Make yourself aware of these potential summer drain issues before they strike.

Most of us associate drainage problems with the winter time, whether it be associated with heavy down pours of rain, flooding, or frozen pipes. But we rarely consider the risks posed to our homes' drainage systems during the hot summer months that can cause equal damage and disruption to their proper functioning.

Typical British summer?

Whilst we sometimes joke about the 'typical British weather' and conjour up images of torrential downpours on bank holiday weekends, the fact is British summers are getting hotter and hotter.

2019 saw the highest daily maximum temperature on record in England at a scorching 38.7 degrees Celsius, and according to the Met Office, all signs are pointing to another warmer than average summer in 2020 with rainfall expected to remain at normal levels.

When things heat up

Although we probably don't give it much thought when we are primarily concerned with cooling down ourselves, it's not just us that heat up when the warmer weather arrives, so do the homes we live in and the pipes that run throughout them to form the drainage system.

A rare but none-the-less significant occurrence caused to properties by extreme heat is subsidence. When subsidence occurs, there can be a number of knock-on effects, one being damage to your drainage system. This can cause severe disruption in cases where the property concerned uses a septic tank or sewage treatment plant and can result in costly, inconvenient repair work.

Far more common is the direct impact seen from unusually hot weather on the pipes themselves. This is thanks to many of the pipes used in drainage systems being made of plastic which is susceptible to cracking and fracturing when exposed to the sun. This occurs where your pipes leave the building interior or ground which is common on most houses.

Further to the pipes cracking, the ground surrounding your drain pipes can also experience cracking. Surfaces like tarmac, for example, frequently crack and melt to various extents over the course of the summer. In some cases, this can lead to nearby drain pipes being damaged, moved or exposed to direct sunlight.

Prevention isn't always possible

When it comes to drain care, we are big fans of prevention as significant amounts of lost time, expense and inconvenience can be negated by taking some simple measures and being proactive with your drain maintenance.

However, in the case of damage caused by heat there isn't much you can do by way of prevention. The best you can do is be aware of the potential damage that can occur when the weather heats up, and keep an eye out for any signs of the early onset of damage to your drains or the ground around your drains.

One benefit of the heat when it comes to drainage is that the limited amounts of rain make the perfect conditions for CCTV camera surveys and repairing pipes. Should your drains get damaged, the extent of the knock-on damage is potentially reduced when compared to colder or wetter times of the year.
