Pitch fibre drains were widely installed in homes across the UK between the 1950s and 1970s, including many properties in Northampton. These pipes were a popular choice at the time due to their affordability and easy installation. However, as they age, pitch fibre drains tend to develop a range of problems, causing recurring drainage issues for homeowners.
If your Northampton property has pitch fibre drains, it’s important to know what problems to look out for and how to fix them before they escalate into major repairs. In this article, we’ll explore the common issues associated with pitch fibre drains and the most effective fixes to keep your drains in good working order.

What Are Pitch Fibre Drains?
Pitch fibre drains are made from a combination of wood cellulose fibres and coal tar pitch. This material was favoured in the mid-20th century due to its low cost and ease of installation, especially in comparison to more traditional clay pipes. However, despite these benefits, pitch fibre drains are not as durable and have a shorter lifespan than other pipe materials.
Why Were Pitch Fibre Drains Popular?
During the post-war housing boom, there was a significant demand for affordable and easy-to-install materials. Pitch fibre, being lightweight and flexible, allowed for faster installation in new housing developments across the UK. For years, they performed adequately, but as these pipes age, their weaknesses become more apparent.
Common Issues with Pitch Fibre Drains
As pitch fibre drains age, they begin to deteriorate, causing a host of problems that can lead to blockages, leaks, and even collapses. Let’s explore the most frequent issues encountered with these types of drains.
1. Deformation and Collapsing
One of the most common problems with pitch fibre drains is deformation. Over time, the pipes can become soft and lose their shape, especially under the pressure of soil or tree roots. This can restrict water flow or, in severe cases, cause the pipes to collapse entirely.
2. Blistering
Blistering occurs when the inner walls of the pitch fibre pipe start to bubble. This is often caused by chemical reactions or prolonged exposure to moisture. These blisters can lead to blockages or, worse, weaken the structural integrity of the pipe.
3. Root Ingress
Tree roots are naturally drawn to moisture and will seek out any weak points in your drainage system. Pitch fibre pipes, which degrade over time, can develop cracks or gaps that allow roots to invade. Once inside, the roots grow and cause severe blockages or even break the pipe further.
4. Cracks and Leaks
As the pitch material weakens, it becomes prone to cracks. These cracks can allow wastewater to escape into the surrounding soil, leading to further environmental damage and potential health risks. Additionally, cracks can widen over time, making the pipe vulnerable to collapse.
Signs Your Pitch Fibre Drains Need Repair
If you’re unsure whether your property has pitch fibre drains or if these drains need repair, keep an eye out for the following signs:
1. Slow Draining Water
A slow-draining sink or bathtub could indicate a blockage somewhere in your drainage system. If you have pitch fibre drains, the blockage could be caused by pipe deformation or blistering.
2. Foul Smells
Bad odours coming from your drains are a sign of trapped wastewater or sewer gases. This could indicate that your pitch fibre drains have developed cracks or are experiencing blockages.
3. Repeated Blockages
If you find yourself frequently dealing with blocked drains, this could suggest a more serious underlying issue with the structure of your pitch fibre pipes.
4. Gurgling Sounds
Gurgling sounds from your pipes are often a sign of trapped air caused by a blockage. With pitch fibre pipes, this can be due to blistering, root ingress, or even partial pipe collapse.
Effective Fixes for Pitch Fibre Drains
While the issues surrounding pitch fibre drains can seem overwhelming, there are several effective solutions that can restore your drainage system to full functionality. Here are the most common repair methods used by professionals.
1. Drain Lining
Drain lining, also known as cured-in-place pipe (CIPP) lining, is a popular method for fixing damaged pitch fibre drains. This trenchless repair solution involves inserting a flexible resin liner into the pipe, which hardens and forms a new inner layer, effectively sealing any cracks, blisters, or deformities.
Benefits of Drain Lining:
- No need for extensive excavation.
- Cost-effective compared to full drain replacement.
- Strengthens the existing pipe without reducing flow capacity.
2. Pipe Re-Rounding
For pipes that have deformed or collapsed slightly, pipe re-rounding is an ideal solution. This process involves using specialised equipment to push the pipe back into its original circular shape. Once the pipe has been restored, it can be lined to prevent future deformation.
Why Choose Pipe Re-Rounding?
- Restores the shape of the pipe without the need for replacement.
- Allows for the application of additional repair methods, like drain lining.
3. Full Drain Replacement
In some cases, the damage to pitch fibre drains is too severe for repair methods like lining or re-rounding. If this is the case, a full drain replacement may be necessary. This involves removing the damaged sections of pipe and installing new, more durable materials such as PVC or clay.
Advantages of Full Replacement:
- Provides a long-term solution with modern, durable materials.
- Prevents future issues related to aging pitch fibre pipes.
4. Root Removal
If your drains are suffering from root ingress, professional root removal is required. Drain specialists use mechanical or hydro jetting techniques to remove the roots and clear the blockage. Once the roots are removed, repairs such as lining can be carried out to prevent future ingress.
The Importance of Professional Repairs
Given the complexity of pitch fibre drain issues, it’s essential to seek professional help for any repairs. Attempting to fix these problems yourself can lead to further damage and more costly repairs down the line.
Why Hire Professionals for Pitch Fibre Drain Repairs?
- They have specialised equipment to assess and repair the damage.
- They can offer trenchless solutions, saving your property from unnecessary excavation.
- They ensure the repairs are long-lasting and meet industry standards.
Maintaining Your Pitch Fibre Drains
After your pitch fibre drains have been repaired, regular maintenance is crucial to prevent future problems. Here are some tips to help you keep your drainage system in good condition.
1. Regular Inspections
Schedule annual inspections with a professional to assess the condition of your pipes. Early detection of issues can save you from costly repairs in the future.
2. Avoid Flushing Problematic Items
Be mindful of what you flush down your drains. Avoid pouring grease, oil, or fat into your sink, and never flush items like wet wipes, sanitary products, or cotton buds down the toilet.
3. Tree Root Management
If you have trees near your drainage system, consider removing them or managing their growth to prevent root ingress. Regular inspections can also help detect roots before they become a significant issue.
