The pipes and plumbing in your home or business are one of those things that you use every day without giving them a second thought until they aren’t working.

Though your sewer pipes are usually out of sight and out of mind, when they start leaking or malfunctioning, it is going to be unpleasant for everyone.

This is a common problem with older pipes which leads us to some big questions – how old is too old for a sewer drain?

How long do sewer pipes even last? 

In this blog, we’re going to answer the above questions and discuss some easy ways to tell whether you need to get your pipes checked and what the best solutions may be. 

How long should your sewer pipes last for? 

The length of time your sewer line lasts will vary depending on the material your pipes are made from. Brass, galvanised steel, and cast-iron pipes tend to have a lifespan of around 80-100 years, whereas copper lasts 70-80 years and PVC pipes last between 24-45 years.

Environmental factors as well the severity of your general wear and tear will play a role in how long your pipes last. 

Tree roots are one of the most common causes of damaged sewerage pipes. The roots are seeking water and nutrients to sustain the tree and your sewerage pipe is the perfect source.

Other outside factors that could damage your pipes are natural disaster, very severe temperature changes, accidentally hitting the pipe during construction and anything going through the pipes that shouldn’t, such as harsh chemicals or rubbish.  

Signs your old sewer pipes need to be checked 

Damaged or blocked sewer pipes, whether due to age or external forces, are something you’ll want to take care of sooner rather than later.

The good news is there are some tell-tale signs that there may be a crack or damage to your piping.

Common signs of damage include:

  • A sewer smell: This will be a bad odour coming from your drains that is almost impossible to miss and sure sign there is an issue with your sewer pipe. 
  • Constant blockage and backups: If you’re finding your pipes are constantly blocked and backing up, you should get this looked at ASAP, as it could be a sign your pipes are damaged. 
  • Slow drainage: When pipes are working properly, drainage should be a smooth process without delay. If drainage is staggered and feels like it’s taking forever, it’s a sign something is blocking your pipes. 
  • Mould and water damage: Water damage will look like stains on the wall and can also make the material feel soft to the touch. Mould takes time to grow, so if you see any near your pipes, they’ve probably been leaking for several days. 
  • Lush Green Patches: Sewerage works as a fertiliser so if you see unexplained green, damp patches on your lawn, it’s strong indication your sewer pipes are leaking. 
  • Indentations in your lawn or under pavers: If your pipes are cracked, soil will start to enter, and this will eventually show on the surface. 
  • Cracks in foundation: When left long enough, a leaking pipe can lead to cracks in flooring and in cement pathways. 

If you notice any of the above, have a professional come and check your pipes sooner rather than later.

All of these issues are best fixed as early as possible, because ignoring them will only lead to further problems, and it will cost you more money.
