If you live in Exeter or the surrounding areas, you may have heard of pitch fibre drains. These types of drains were once popular in the UK, but they can cause significant problems as they age. Understanding why pitch fibre drains Exeter might need replacing, how to spot the signs of deterioration, and the best steps to take can save you time, money, and hassle in the long run.
In this article, we’ll explain why pitch fibre drains might need replacement, the common signs of damage, and how you can address any issues before they become major problems.
What Are Pitch Fibre Drains?
Before we jump into the potential problems, let’s first clarify what pitch fibre drains actually are. Pitch fibre pipes were a popular choice for drainage systems in the UK from the 1950s to the 1970s. Made from a combination of wood pulp and bitumen (a form of tar), these pipes were touted as lightweight, flexible, and easy to install. However, while they were initially an attractive option, over time, their drawbacks have become more apparent.
The Common Problems with Pitch Fibre Drains
While pitch fibre pipes may have served their purpose at one point, they are prone to several issues as they age. Over the years, the materials used to create them can break down, leading to a range of drainage problems. Here are some of the most common issues:
1. Cracking and Splitting
One of the most common problems with pitch fibre drains is cracking. As pitch fibre pipes age, the material becomes brittle and more susceptible to cracks and splits. These cracks can lead to leaks, which may cause water to leak into the surrounding soil or even your property. This can result in foul smells, water damage, or even structural damage to your home if left unchecked.
2. Collapsing or Deforming
Another issue with pitch fibre pipes is that they can collapse or deform under pressure. This is particularly true if the pipes are buried too deep or are subjected to ground movement over time. When this happens, the pipes can block, causing drainage issues and preventing waste from flowing properly.
3. Blockages
Pitch fibre drains are also more prone to blockages compared to more modern types of drains. Over time, the porous nature of the material can allow roots, debris, and other waste to build up inside the pipes. This leads to blockages that can cause water to back up and create unpleasant odours in your home.
4. Weakness from Moisture and Age
The combination of moisture and age can weaken pitch fibre pipes, leading to increased susceptibility to damage. As the bitumen in the pipes breaks down, the material can begin to swell or distort, leading to further issues such as blockages and leaks.
Why Do Pitch Fibre Drains Need Replacement?
So why exactly should pitch fibre drains be replaced? While they were once a cost-effective solution, their long-term durability and performance have proven to be problematic. Here are a few reasons why you may need to replace your pitch fibre drains:
1. Long Lifespan – But Not Forever
Pitch fibre drains were designed to last for decades, but like all materials, they have a finite lifespan. Most pitch fibre pipes are now over 50 years old, and many have reached or exceeded their expected lifespan. As the pipes deteriorate, the risk of failure increases, making replacement necessary.
2. Risk of Major Damage
Ignoring the signs of deteriorating pitch fibre drains can lead to much more severe problems down the road. If cracks or blockages are not addressed, they can result in major structural issues such as subsidence, flooding, or costly damage to your property. Replacing the drains early can help you avoid these expensive repairs.
3. Modern Alternatives Are More Durable
Today’s drain pipes, such as PVC, are much more durable and long-lasting than pitch fibre. These modern pipes are resistant to cracking, blockages, and other issues. By upgrading your drainage system to a more modern material, you can ensure that your drains remain efficient and functional for many years to come.
How to Tell If Your Pitch Fibre Drains Need Replacing
Knowing the signs of damage in your pitch fibre drains can help you identify when it’s time for a replacement. Here are some key indicators that your drains may need replacing:
1. Frequent Blockages or Slow Drains
If you’re dealing with frequent blockages or notice that water is draining slowly, your pitch fibre pipes may be clogged with debris, tree roots, or waste. This is a sign that the pipes may be damaged and unable to function properly.
2. Unpleasant Odours
If you start to notice foul smells coming from your drains, it could indicate that your pitch fibre pipes are leaking or suffering from damage. This smell is often a sign of stagnant water, sewage, or waste that has escaped the pipe and is causing unpleasant odours inside your home or garden.
3. Cracks or Visible Damage
If you can see cracks, splits, or other signs of physical damage on your pitch fibre pipes, it’s a strong indicator that they need replacing. Damaged pipes can lead to leaks, blockages, and even collapse if left unchecked.
4. Rising Damp or Water Damage
Water damage, such as damp patches on walls, ceilings, or floors, can occur if your pitch fibre drains are leaking or collapsed. If you notice signs of rising damp in areas near your drains, it may be time to consider replacing them.
5. Increased Repair Costs
If you’re constantly paying for repairs to your pitch fibre drains, it might be more cost-effective to replace the entire system rather than dealing with recurring issues. The ongoing repairs can quickly add up, making replacement a more affordable and permanent solution.
How to Replace Pitch Fibre Drains in Exeter
If you’ve determined that your pitch fibre drains need replacing, it’s important to work with a professional drainage company that can carry out the job safely and efficiently. Here’s what you can expect during the process:
1. Survey and Inspection
The first step in replacing your pitch fibre drains Exeter is to conduct a thorough survey. A professional drainage company will use cameras to inspect your pipes and assess the extent of the damage. This will allow them to determine whether replacement is necessary or if repairs can be made.
2. Excavation and Removal
Once it’s clear that the drains need replacing, the next step is excavation. This involves digging up the old pitch fibre pipes and removing them from the ground. It’s important that this process is done carefully to avoid damaging other parts of your property.
3. Installation of New Pipes
After the old pipes are removed, new pipes made from more durable materials, such as PVC, will be installed. These modern pipes are more resistant to damage and are built to last for many years.
4. Testing and Final Checks
Once the new pipes are in place, they’ll be thoroughly tested to ensure they are functioning correctly. This includes checking for leaks, ensuring proper water flow, and conducting other tests to confirm that your new drainage system is fully operational.
Conclusion: Is It Time to Replace Your Pitch Fibre Drains?
Pitch fibre drains may have been a popular choice decades ago, but they’re not the most reliable option today. If your property in Exeter has pitch fibre pipes, it’s essential to monitor for signs of damage and deterioration. Early detection and replacement can save you from costly repairs and serious damage to your property.
If you suspect your drains need replacing, it’s always best to consult with a professional drainage expert who can assess the situation and recommend the best course of action.
