Fibre pitch drain blockages are a significant concern for many homeowners and businesses. These blockages can lead to severe water drainage issues, causing damage and requiring costly repairs. In this article, we’ll explore what fibre pitch drains are, common causes of their blockages, and practical solutions to prevent and resolve these issues.
What Are Fibre Pitch Drains?
Fibre pitch drains, also known as pitch-fibre drains, were widely used in the mid-20th century. Made from wood cellulose impregnated with coal tar, these drains were a popular choice due to their lightweight nature and ease of installation. However, over time, they have been found to be prone to deformation and deterioration, leading to blockages.
Common Causes of Fibre Pitch Drain Blockages
Deformation and Collapse
Over time, fibre pitch drains can become deformed or collapse due to ground movement or the natural deterioration of the material. This deformation reduces the internal diameter of the pipes, restricting water flow and causing blockages.
Root Infiltration
Tree roots are a common cause of blockages in fibre pitch drains. Roots can penetrate the pipes through joints and cracks, growing inside and obstructing the flow of water.
Build-up of Debris
Fibre pitch drains can also become blocked due to the build-up of debris such as fats, oils, grease, and other non-biodegradable materials. These substances can accumulate over time, reducing the pipe’s effective diameter and causing blockages.
What are the problems with pitch fibre pipes?
Pitch fibre pipes, widely used from the 1950s to the 1970s, were considered innovative at the time due to their lightweight nature and ease of installation. However, as these pipes age, numerous issues have emerged, raising concerns for homeowners and businesses. This article explores the common problems associated with pitch fibre pipes and provides insights into how to address them.
Deformation and Collapse
One of the most prevalent issues with pitch fibre pipes is their tendency to deform and collapse. Over time, the material can soften and become misshapen, especially under the pressure of soil and ground movement. This deformation restricts water flow and can eventually lead to complete collapse of the pipe, causing severe blockages and requiring extensive repairs.
Root Infiltration
Tree roots are naturally drawn to the moisture within pipes. Pitch fibre pipes are particularly susceptible to root infiltration due to their softer material and joint weaknesses. Once roots penetrate the pipes, they can grow inside, causing significant blockages and potentially breaking the pipes further.
Blistering and Delamination
Pitch fibre pipes are prone to blistering and delamination, where layers of the pipe begin to separate. This can create pockets within the pipe where debris accumulates, leading to blockages. These blisters can also weaken the structural integrity of the pipes, making them more likely to collapse.
Signs of Problems with Pitch Fibre Pipes
Frequent Blockages
If you experience frequent drain blockages, it could be a sign that your pitch fibre pipes are deformed or infiltrated by roots.
Slow Drainage
Slow drainage in sinks, toilets, or baths can indicate a partial blockage within the pitch fibre pipes, often due to deformation or debris build-up.
Unpleasant Odors
Foul smells coming from your drains are a common sign of blockages or damage within the pipes, causing waste to accumulate and emit odors.
Visible Deformation
In some cases, you might notice visible deformation or blisters on exposed sections of pitch fibre pipes, indicating significant deterioration.
Addressing the Problems with Pitch Fibre Pipes
Inspection and Diagnosis
The first step in addressing issues with pitch fibre pipes is to conduct a thorough inspection. Professional plumbers can use CCTV cameras to inspect the interior of the pipes and identify the exact nature and location of the problems.
Pipe Relining
Pipe relining is a popular solution for repairing damaged pitch fibre pipes without excavation. This process involves inserting a resin-coated liner into the existing pipe. The liner is then inflated and cured, creating a new, durable pipe within the old one.
Pipe Replacement
In cases of severe damage or widespread issues, replacing the pitch fibre pipes with modern materials like PVC or HDPE may be necessary. While this is a more extensive and costly solution, it provides a long-term fix and eliminates the problems associated with pitch fibre pipes.
Regular Maintenance
To prevent future issues, regular maintenance of your drainage system is essential. This includes periodic inspections, cleaning, and addressing minor problems before they escalate.
Identifying Blockages in Fibre Pitch Drains
Slow Drainage
One of the first signs of a blockage in fibre pitch drains is slow drainage. If you notice that water is draining slowly from sinks, baths, or showers, it may indicate a blockage.
Gurgling Sounds
Gurgling sounds coming from the drains are another indication of a blockage. These sounds are caused by trapped air trying to escape through the water in the pipes.
Foul Odors
Blocked drains often produce unpleasant odors. If you notice foul smells coming from your drains, it’s a sign that there may be a blockage.
Preventing Fibre Pitch Drain Blockages
Regular Inspections
Regular inspections of your drainage system can help identify potential issues before they become severe. A professional plumber can use specialized equipment to inspect the inside of the drains and detect any deformations or blockages.
Proper Waste Disposal
Proper waste disposal is crucial in preventing blockages. Avoid pouring fats, oils, and grease down the drain, and dispose of non-biodegradable items such as wet wipes and sanitary products in the trash.
Root Barriers
If tree roots are a concern, installing root barriers can help prevent them from infiltrating your drains. These barriers can be placed around the pipes to block root growth.
Resolving Fibre Pitch Drain Blockages
Mechanical Cleaning
Mechanical cleaning involves using specialized tools to remove blockages. A drain snake or auger can be inserted into the drain to break up and remove the obstruction.
Hydro Jetting
Hydro jetting uses high-pressure water jets to clear blockages. This method is effective in removing debris and roots from the drains, restoring proper water flow.
Pipe Relining
Pipe relining is a method used to repair deformed or collapsed fibre pitch drains. A resin-coated liner is inserted into the damaged pipe and inflated, creating a new, durable inner layer.
Pipe Replacement
In severe cases, replacing the fibre pitch drains may be necessary. Modern materials such as PVC or HDPE are more durable and less prone to blockages, making them a better long-term solution.
Conclusion!!
Fibre pitch drain blockages can cause significant issues if not addressed promptly. Understanding the common causes and signs of blockages, along with implementing preventative measures, can help maintain the integrity of your drainage system. Regular inspections and proper waste disposal are key to preventing blockages, while mechanical cleaning, hydro jetting, pipe relining, and replacement offer effective solutions for resolving existing issues. By staying proactive, you can keep your drains clear and functioning properly, avoiding costly repairs and inconvenience.
