10 common queries related to drainage issues – and how drainage experts tackle them!

  1. Why is my drain slow to empty?

    A sluggish drain often results from accumulated debris, grease, or mineral deposits restricting the water flow.

    Solution: Expert drainage contractors employ high-pressure jetting to dislodge and clear obstructions. This method ensures a thorough cleaning, restoring optimal flow. Regular professional cleaning prevents future slowdowns, maintaining the efficiency of your drainage system in Orpington or London.

  2. What causes foul odours from drains?

    Unpleasant odours emanate from drains due to trapped debris, decaying matter, or a dried-out U-bend, allowing sewer gases to escape.

    Solution: Expert engineers tackle this by conducting a comprehensive drain inspection to identify and remove the source of the smell. Regular maintenance, including U-bend checks and proper waste disposal, ensures a fresh-smelling environment, enhancing comfort for residential and commercial spaces alike.

  3. How can tree roots affect my drains?

    Tree roots infiltrate drains seeking water, causing blockages and structural damage over time.

    Solution: An expert drainage contractor utilises advanced technology like CCTV surveys to pinpoint root ingress. They then employ techniques such as root cutting and trenchless repairs to mitigate damage. Regular inspections and root barrier installation prevent future issues, preserving the integrity of your drainage system.

  4. What to do if I have a blocked toilet?

    A blocked toilet occurs when items like sanitary products or excessive toilet paper obstruct the pipes.

    Solution: Experts will address this promptly with drain rods or specialised equipment, ensuring blockages are efficiently cleared without causing damage. Advising on proper toilet use and disposal practices, they help prevent future blockages, providing peace of mind to clients.

  5. Is there a quick fix for a clogged sink?

    A clogged sink results from a buildup of grease, soap, or foreign objects in the pipes.

    Solution: Drainage professionals employ drain augers or plungers to dislodge blockages swiftly. They also educate clients on proper sink usage and provide eco-friendly drain cleaning solutions. Regular maintenance prevents recurrent clogs, maintaining a free-flowing sink in homes and businesses.

  6. How do I identify a drainage emergency?

    Recognising a drainage emergency involves identifying signs like sudden leaks, foul odours, or sewage backup.

    Solution: Swift action is crucial. At BN Drainage, we guide clients to turn off water sources, contact professionals immediately, and, if safe, contain the issue. Our emergency services swiftly address the problem, minimising damage and restoring normalcy to homes and businesses in Swanley, Bromley, and surrounding regions.

  7. Can I use chemical drain cleaners?

    Wondering about the efficacy and safety of chemical drain cleaners is common.

    Solution: Chemical drain cleaners can cause pipe corrosion and harm the environment. Instead, we recommend mechanical methods like drain snakes or enzymes that break down blockages without causing harm. Choosing eco-friendly alternatives ensures a safer and more sustainable approach to drain maintenance.

  8. How often should I have my drains inspected?

    Understanding the frequency of drain inspections is essential for proactive maintenance.

    Solution: Regular inspections every 12-24 months, or more frequently in high-use areas, prevent potential issues. CCTV surveys provide a detailed view, allowing for early detection of concerns. This proactive approach ensures a well-maintained drainage system, reducing the risk of unexpected problems for properties in London.

  9. What’s the importance of gutter maintenance?

    The significance of maintaining gutters may not be apparent to all.

    Solution: Well-maintained gutters prevent water damage to your property by directing rainwater away. Regular gutter cleaning removes debris, avoiding blockages that can lead to leaks and structural issues. This simple yet vital task preserves the integrity of your residential or commercial space, safeguarding it from potential water-related damage.

  10. How to handle a burst pipe?

    Facing a burst pipe is a stressful situation that requires immediate attention.

    Solution: Quickly turn off the water supply, locate the burst pipe, and use a temporary patch until professional help arrives. Our emergency repair services swiftly address burst pipes, minimising water damage. Educating clients on these initial steps empowers them to take immediate action, reducing the impact of a burst pipe on their property.

5 preventive measures you can (and should) take

  1. Regularly clear debris from gutters

    Proactively maintaining your gutters is akin to giving your property a shield against potential water damage. Regularly removing debris such as leaves, twigs, and dirt prevents blockages, ensuring rainwater can flow freely.

    This simple yet effective measure safeguards your roof, walls, and foundation from the detrimental effects of water overflow. Especially in locations like Orpington and London where rain is frequent, this practice is paramount.

  2. Avoid flushing non-biodegradable items

    The seemingly convenient act of flushing non-biodegradable items down the toilet can lead to significant plumbing issues. Items like wipes, sanitary products, and paper towels don’t break down easily, causing blockages and strain on your drainage system.

    Adopting a responsible approach by disposing of these items in designated bins can prevent unnecessary clogs, reducing the likelihood of costly repairs. This small adjustment in behaviour contributes to the long-term health of your plumbing and the overall efficiency of your drainage system.

  3. Install drain guards to prevent debris buildup

    Installing drain guards is a proactive step towards maintaining a healthy drainage system. These simple devices act as filters, preventing larger debris from entering and causing blockages.

    By capturing leaves, twigs, and other potential obstructions, drain guards allow water to flow freely. This preventive measure is particularly valuable in areas like Chislehurst and Swanley, where environmental factors contribute to debris accumulation.

    Regularly cleaning and emptying drain guards ensure they continue to function optimally, providing ongoing protection for your drainage system.

  4. Monitor and address slow drainage promptly

    Paying attention to the speed at which water drains is a key indicator of potential issues within your plumbing. If you notice slow drainage in sinks, showers, or toilets, it could be a sign of developing blockages.

    Addressing this promptly by using safe and effective drain-cleaning methods or seeking professional assistance prevents the problem from escalating. Timely intervention not only ensures the uninterrupted flow of water but also helps maintain the overall health of your drainage system, preventing more significant and costly issues down the line.

  5. Schedule routine professional drain inspections

    Regular professional drain inspections are a proactive approach to identifying and addressing potential problems before they become major issues.

    Through advanced technologies like CCTV surveys, drainage experts at BN Drainage can assess the condition of your pipes, detecting any signs of damage, blockages, or wear. This preventative measure allows for timely intervention, minimising the risk of emergencies and ensuring the longevity of your drainage system.

    Particularly in Bromley, where diverse factors can impact drainage, scheduled inspections serve as a reliable strategy for maintaining optimal functionality and preventing unexpected disruptions.
