Blocked drains can be a pain, no matter how or when they occur. But when you’re faced with a blocked drain, the inevitable question of how to get rid of it might be prefaced with: will it simply go away on its own? This idea, while appealing, requires a deeper understanding of the nature of drain blockages and the factors that affect them - so let’s take a closer look.
Drain blockages come in various forms, and in most cases are dictated by what goes down the drain. Common culprits for drain blockages include hair, grease, food debris, and foreign objects, and each of these types of blockage behaves differently, which is why it’s impossible to say whether or not a blocked drain will simply clear itself on its own. It really comes down to two simple words: it depends.
So, how do blockages actually progress? Initially, blockages may start as minor obstructions that slightly impede water flow, but over time - and if not treated - certain blockages can accumulate more debris, worsening the problem and making professional intervention a necessity. And again, it’s important to point out the possibilities at play here: the progression of a blockage will always depend on various differentiating factors, including the type of debris and the usage of the drain.
So, under what circumstances may a blocked drain clear itself? Let’s take a look:
It’s important to understand the role of gravity: gravity and the natural flow of water can sometimes aid in dislodging smaller blockages, especially those comprised of loose, non-sticky materials. However, this is less likely with more substantial or adhesive blockages.
Organic material, such as food scraps or natural debris, may eventually break down and pass through the system, as they’re more easily broken down by things like hot water, which will naturally pass through the pipe at some point. This process, however, can be slow and unpredictable, and can also often lead to unpleasant odours and the risk of attracting pests.
Seasonal changes and weather conditions can also impact drainage; heavy rain, for example, can sometimes help to push blockages through the system, while cold weather can cause substances like grease to solidify, exacerbating blockages and making self-drainage pretty much impossible.
In some cases after a minor blockage, you might notice gradual improvements in drainage speed, and this can - in some cases - indicate a possible self-clearing process. However, this isn;t a guarantee that the problem is resolved; we’d always advise caution, as partial blockages can quickly become complete and require intervention from a plumber.
Many believe that pouring boiling water down the drain is a cure-all for blockages, and while hot water can help dissolve certain substances like grease, it's not a universal solution. In some cases, it can even worsen the blockage or damage the pipes, especially if they’re old or worn.
The convenience of chemical drain cleaners is undeniable, but they're not always the best option. These chemicals can be harsh, potentially damaging pipes over time and posing environmental and health risks - plus, for some types of blockages, they may be ineffective or only provide a temporary fix.
While a plunger can be effective for dislodging certain clogs, it's not a universal tool for all types of blockages. Deep or solid blockages, especially those further along the pipe system, often require more specialised techniques or professional intervention, so using a plunger is unlikely to make much of a difference.
When it comes to any plumbing issue in your home, timely intervention is absolutely essential in ensuring that the problem doesn’t get worse over time. Ignoring or waiting for a blockage to clear itself can lead to complications such as pipe damage, unpleasant odours, and even health hazards; in the worst case scenario, a pipe could even burst and cause costly damage to your home. So no matter how small you think the blocklage might be, we’d always advise you to address problems promptly, either through DIY methods for minor issues or by seeking professional help for more significant blockages.
