Cotswold Drainage cleared a blocked drainage pipe from our septic tank. Not the easiest access and a combination of pipe and soakaway to investigate. Adrian was excellent - prompt, friendly and willing to go the extra yard when things were looking difficult. Very pleased with the service.
- Geoff Smith
Used this company a couple of times now. Staff always great and they turn up when they say. Never had any problems, work always done properly. Would recommend.
- Rachel Godfrey
Very knowledgeable and polite, quickly cleared the drain and washed it out.
- Alan Grove
A quick and professional service. Russell the operator soon had our problem solved
- Donald Gilder
From start to finish Nikki and the team were brilliant . Quotes through quickly and house buying drainage survey results through in a couple days. Would highly recommend this company. Thank you all.
- Carrie Crinage
Professional and reliable with first class service, definitely recommend. We had an issue with an ACO drain in the recent torrential storms which caused flooding in our integral garage. Having been flooded in two previous properties before this occasion and now being paranoid about water, we wanted to rectify the situation quickly to mitigate any future problems. We searched the Internet looking for a professional, trustworthy company who we could rely upon to fix the issue quickly and provide us with peace of mind. We found and researched Cotswold Drainage, particularly taking into account the customer feedback and first class reviews in our decision. We couldn't be more delighted from our initial contact with Nikki, two site visits one by Dave to review the issue quickly followed up by Adrian for a camera inspection, to Keith who carried out the work over 3 days in the most awful of weather (rain, drizzle and bitterly cold). Keith worked flat out every day at the same time always professional, cheerful and courteous. We cannot fault them and and would highly recommend them.

    What are pitch fibre pipes?

    Introduced around the 1950s, Pitch fibre pipes revolutionised the plumbing scene in the UK. Initially celebrated for their cost-effectiveness and ease of installation, these pipes made their way into both residential and commercial properties. Composed of a mix of cellulose fibres and coal tar pitch, they offered a more affordable alternative to traditional clay and metal pipes.

    The average lifespan of a pitch fibre pipe is around 40 years. As a result, the pipes are now prone to certain issues. There has recently been an increasing need for professional surveys and repairs. Some of these pipes incorporated asbestos, which has raised additional safety concerns. Ongoing maintenance and timely repairs are now crucial for properties with pitch fibre pipes.

    Drain unblocking process

    There are still a number of positive properties for pitch fibre pipes. They are non-corrosive, setting them apart from metal pipes that are susceptible to rust and decay. The non-corrosive nature of pitch fibre lines allowed them to be used in various environments without risking material degradation.

    Their low thermal conductivity makes them energy-efficient. Unlike metal pipes, which can lose heat rapidly, pitch fibre pipes maintain their thermal integrity, contributing to energy conservation in heating systems.

    Pitch fibre drains are flexible and can adapt to various ground conditions. However, this flexibility can also be a double-edged sword. While it makes the pipes versatile and easier to work with, it also means they're more likely to deform under substantial weight or pressure. Regular inspections are necessary to catch any signs of deformation early before it escalates into a more severe issue.

    Common Issues with Pitch Fibre Drain Pipes

    One of the most common issues is blistering and deformation. The blister formation can eventually lead to significant structural weaknesses, which can cause the pipes to collapse and completely block the drains.

    Root infiltration can be another recurring problem. Over time, the weakened structural integrity of these pipes becomes an easy target for tree roots. Roots can penetrate compromised areas of the pipes, leading to clogs and potential collapses.

    Pitch fibre pipes are also prone to internal sludge buildup, further exacerbating drainage problems. The material’s tendency to trap waste material can lead to stubborn blockages that require professional cleaning, or jetting.

    External pressures such as soil weight can increase the risk of pipe collapse. The same flexibility that makes these pipes easier to install can also be their undoing when subjected to heavy, consistent pressure from the surrounding soil.

    Unblocking a drain

    Visible signs of issues often include slow drainage and frequent blockages. Recognising these symptoms early can prompt timely intervention, preventing more severe damage and costly repairs. Regular monitoring and professional inspections can help you stay ahead of these common issues, ensuring your drainage system operates smoothly.

    Timely repairs of pitch fibre pipes can help to prevent severe property damage caused by undetected leaks. If damaged pipes are left unrepaired than can eventually cause extensive water damage, which can be both costly and disruptive. 

    Fixing problems early also extends the lifespan of the pipes. By addressing minor defects before they escalate, you can prolong the duration of your pitch fibre pipes. This proactive approach ensures that you get the most out of your existing drainage system and can be very cost-effective in the long run.
