Blocked drains are one of the most common plumbing issues homeowners face. While they might seem like a minor inconvenience, they can quickly turn into a bigger problem if not handled properly. At Curran, we know that dealing with a blocked drain can be frustrating, but knowing the right steps to take can save you time, money, and prevent further damage!
Here’s what you should (and shouldn’t) do when you’re faced with a blocked drain.
What You Should do!
Assess The situation
First, check if the blockage is affecting just one drain (like a sink or shower) or multiple drains. If multiple drains are clogged, this could indicate a more serious issue, such as a blockage further down the pipe or even in the main sewer line. A single drain issue is often easier to resolve.
try a plunger
A plunger is your first line of defence when it comes to clearing a blocked drain. It’s especially effective for sinks, bathtubs, and toilets. Make sure the plunger creates a good seal around the drain, and use quick, forceful thrusts to dislodge the blockage.

Use Boiling Water
For kitchen sinks, pouring boiling water down the drain can help break down grease, soap scum, and food particles. This is a simple method you can try before resorting to more drastic measures.
Consider a Drain Cleaner (With Caution)
If you opt to use a store-bought drain cleaner, be careful. These chemicals can sometimes damage your pipes or make the blockage worse if used incorrectly. Always follow the instructions carefully, and if you’re unsure, consult a professional plumber to avoid causing damage to your plumbing system.
Call the Experts at Curran
If the blockage persists after trying the methods above, it’s time to call in the experts. At Curran, we have the tools and experience to locate the source of the blockage and clear it quickly and safely. We use advanced equipment, such as drain cameras and hydro-jetting, to ensure the job is done right.

What You Shouldn't do!
Don’t Use Harsh Chemicals Regularly
While it may be tempting to reach for strong chemical drain cleaners, frequent use can cause long-term damage to your pipes. Over time, these chemicals can erode the inner walls of your plumbing, leading to leaks and even pipe bursts. Instead, opt for professional plumbing services if you need regular drain cleaning.
Don’t Ignore Slow Drains
If you notice your drain is moving slower than usual, it could be the first sign of a blockage. Ignoring a slow drain might seem like a minor issue, but over time, it can lead to more significant blockages that are more expensive to repair. Don’t wait—address the issue early with a plumbing inspection.

Don’t Attempt DIY Solutions If You’re Unsure
While some DIY methods can work for simple blockages, attempting more advanced plumbing fixes without the proper tools or knowledge can make the situation worse. If you’re not sure, it’s always best to consult with a professional plumber who can resolve the issue safely and efficiently.
Don’t Dump Grease or Large Debris Down the Drain
A blocked drain is often caused by grease, oils, hair, or other debris that shouldn’t be washed down the drain. Avoid pouring grease or food scraps down the kitchen sink, and make sure to install hair catchers in bathroom drains to reduce the chances of blockages.
