    Blocked Drains

    Blocked drains can be a common and frustrating problem many homeowners and property owners face. Whether it’s a clogged sink, shower drain, or toilet, a blockage can disrupt daily activities and cause inconvenience. Understanding the causes and how to unblock drains is essential in maintaining a healthy plumbing system and preventing further complications.

    Common Causes of Blocked Drains

    Blocked drains can occur due to various factors, and understanding these causes can help prevent and address the issue effectively. Below are some main causes of blocked drains:

    Accumulation of Debris: Over time, dirt, leaves, twigs, and other outdoor materials can find their way into outdoor drains and gutters, leading to blockages. Similarly, indoor drains can get clogged with hair, food particles, soap residue, and other debris.

    Grease and Fat Buildup: Pouring grease and fat down the kitchen sink is a common mistake that can lead to blockages. When hot grease or fat cools down, it solidifies and sticks to the inside of the pipes, eventually causing a buildup that restricts water flow.

    Foreign Objects: Accidentally or intentionally flushing foreign objects down the toilet or letting them go down the sink can result in blocked drains. Items like sanitary products, diapers, paper towels, and even children’s toys can get stuck in the pipes and cause obstructions.

    Tree Root Intrusion: Underground pipes can be invaded by tree roots seeking moisture. As roots grow and spread, they can crack or damage the pipes, leading to blockages. This is more common in older plumbing systems or areas with a high concentration of trees.

    Structural issues: Damaged or deteriorating pipes due to age, corrosion, or shifting soil can obstruct the drains. Cracks collapses, or misaligned pipes can trap debris and cause water flow problems.

    Incorrect Pipe Installation: Poorly installed or improperly aligned pipes can contribute to drain blockages. If pipes have incorrect gradients or are not connected properly, water may not flow smoothly, accumulating debris and eventual blockages.

    Hard Water Deposits: Over time, pipes in regions with hard water tend to accumulate mineral deposits. This buildup reduces the diameter of the pipe, restricting water flow and potentially causing blockages.

    Weather Conditions: Heavy rainfall or storms can overwhelm drainage systems, causing blockages in both indoor and outdoor drains. Leaves, debris, and excessive water can quickly overload the system and lead to clogs.

    Understanding these common causes of blocked drains can help homeowners take preventative measures, such as regular maintenance, proper waste disposal, and professional inspections, to minimise the occurrence of blockages and keep their plumbing systems running smoothly.

    Why It’s Pertinent to Open Drains?

    Unblocking drains is essential for several reasons. Firstly, blocked drains can cause significant inconvenience and disrupt daily activities. Whether it’s a clogged sink, shower, or toilet, the inability to use these essential fixtures can be frustrating.

    Secondly, blocked drains can lead to unpleasant odours and unhygienic conditions. The presence of stagnant water and trapped debris can create an ideal breeding ground for bacteria, mould, and other harmful microorganisms, which pose significant health risks to the occupants of the property.

    Furthermore, if neglected, blocked drains can result in water damage to nearby surfaces such as walls, floors, and ceilings, necessitating expensive repairs.

    Lastly, unblocking drains helps maintain the integrity of the plumbing system. Removing obstructions and ensuring proper water flow minimises the risk of further plumbing issues, such as pipe bursts or leaks.

    Overall, unblocking drains is crucial for a property’s plumbing system’s comfort, health, and functionality.

    Solving the Nightmare: How to Unblock an Outside Drain

    Step One:

    Assess the Problem Don’t panic! Take a moment to evaluate the situation. Is the blockage visible or hidden? Is it a simple clog or a more challenging task? If you’re confident tackling it yourself, proceed to the next step. However, it’s best to seek professional help if it seems overwhelming.

    Step Two:

    Gear Up for Action Before diving into the drain, gather the necessary tools. Get yourself a drainage rod, the superhero of unblocking outside drains. Don’t forget to wear waterproof gloves, long sleeves, and protective gear for your mouth and eyes. Safety first! Also, grab a bucket and a hose, preferably a pressure hose if available.

    Step Three:

    Remove Reachable Blockages If you can reach into the drain with your arm, go ahead and pull out any visible blockages. It’s not a pleasant task, but it’s worth it. Place a bucket nearby to collect the debris and remove it as much as possible. This will make the next steps easier.

    Step Four:

    Take on the Blockage Time to unleash the power of your drainage rod. With determination, plunge it into the sludge, applying gentle pressure as needed. Twist the rod clockwise to avoid any unscrewing mishaps. Break up the blockage by moving the rod around. Patience is key here, especially for stubborn buildups. Keep at it until the drainage becomes smoother and the blockage dissipates.

    Step Five:

    Tidy Up the Surroundings Now that water flows freely through the drain, take a moment to prevent future issues. Use your hose, preferably with pressure, to remove any remaining debris around the drain. Water must be pushed forcefully to dislodge any loose remnants. The cleaner your drains, the longer you’ll enjoy a blockage-free environment.

    Step Six:

    When All Else Fails, Seek Professional Help. Sometimes, even our best efforts don’t yield the desired results. If your outside drain remains stubbornly blocked, it’s time to call in the experts. Trying more extreme techniques can cause damage and worsen the problem. Let the professionals handle the situation and restore your drainage system effectively.


    Remember, unblocking an outside drain might seem daunting, but you can conquer it with the right approach and tools. Assess, gear up, remove reachable blockages, tackle the main blockage, tidy up, and rely on professionals to save the day if needed. Don’t let a blocked outside drain dampen your piping, take action and reclaim your outdoor plumbing system.
