How to Use a Plunger to Clear Clogged Sinks and Toilets

Picture this - you're brushing your teeth or flushing the toilet, and suddenly, the water begins to rise rather than disappear down the drain. The dreaded clogged sink or toilet blockage is not only inconvenient but can also lead to serious plumbing issues if ignored. Fortunately, there's a simple, time-tested tool that comes to the rescue in these situations – the plunger.

If you're in Hamilton and dealing with plumbing woes, learning proper plunger techniques could save you both time and money. Here's a guide to help you master the art of plunging and tackle those stubborn clogs.

Why do drains and toilets clog?

Before you grab your plunger, take a moment to understand why clogs happen. For sinks, common culprits include hair, grease, soap scum, and food particles stuck in the pipes. Toilets tend to get blocked by flushing too much toilet paper, non-flushable items, or debris that builds up over time. Knowing what causes the problem can help you prevent future blockages.

Choosing the right plunger

Not all plungers are created equal. Having the right one for the job can make a big difference. Here are the two types you should know:

Cup Plunger: Ideal for flat surfaces like sinks or tubs. It has a simple rubber cup at the bottom.
Flange Plunger: Best for toilets. It features a rubber cup with an additional flange at the end, which provides a better seal for th

If you're only going to invest in one plunger, consider getting a multi-purpose flange plunger that works for both sinks and toilets.

Step-by-step guide to using a plunger effectively

1. Prepare the Area

Before you begin, ensure there's enough water in the sink or toilet to cover the plunger's rubber cup. If needed, add water manually. This helps create a better seal. Also, place towels on the floor to catch any splashes.

2. Position the Plunger

For sinks: Place the plunger directly over the drain, ensuring it fully covers the opening.
For toilets: Insert the plunger into the bowl, making sure the flange at the bottom forms a tight seal with the drain.

3. Create a Vacuum

Push the plunger down gently at first to eliminate any air inside. A tight seal is crucial for building the necessary suction.

4. Use Steady Motions

Using firm, even strokes, push the plunger down and pull it back up without breaking the seal. Repeat this motion about 10-20 times. The suction and pressure should help dislodge the clog.

5. Check for Results

If water drains easily after plunging, you've successfully cleared the blockage! For stubborn clogs, you may need to repeat the process or use additional tools like a plumber's snake.

6. Clean Up

Wash the plunger thoroughly after use. Disinfect the sink or toilet and sanitize any areas that may have come in contact with dirty water.

When to call professionals

If you've followed these steps and the clog still won't budge, it might be time to call a professional plumber, like the team at A Rescue Rooter. More serious blockages could indicate issues deeper within your plumbing system that require specialized tools and expertise to repair.

Don't wait too long to seek help, as unresolved clogs can lead to pipe damage, leaks, or water overflow.

Pro tips to prevent future clogs

Avoid pouring grease, coffee grounds, or food waste down the sink.
Use sink strainers to catch debris before it goes down the drain.
Avoid flushing anything other than toilet paper and human waste.
Clean your drains regularly with hot water or a vinegar and baking soda mixture.

Knowing how to use a plunger can save you from the stress (and mess) of dealing with a clogged sink or toilet. By choosing the right plunger and following proper techniques, you'll be able to handle most minor blockages like a pro. However, don't hesitate to reach out for help if the clog proves too stubborn. With the plumbing experts at Rescue Rooter in Hamilton, your drains will be clear and functional in no time.

The Water Pressure at Home is Dropping

By Robbie Balla • April 28, 2025

Low water pressure is more than just an inconvenience—it can be a sign of a deeper plumbing issue. Whether you’re brushing your teeth, running the dishwasher, or trying to enjoy a relaxing shower, reduced water pressure disrupts your daily routines and could point to hidden problems in your home’s plumbing system. But how do you know when it’s time to call a professional plumber? Here’s a detailed guide to help homeowners and plumbers decide the right course of action when the water pressure starts to drop. Common Causes of Low Water Pressure Mineral Build-up in Pipes Over time, mineral deposits from hard water can accumulate inside your plumbing pipes, reducing the flow of water. Areas with hard water are particularly prone to this problem, and once it starts, it tends to worsen if left unaddressed. Leaky Pipes A hidden leak in your plumbing system can drastically reduce water pressure. Not only does this waste water (and increase your bill), but it can also cause significant property damage if not handled quickly. Clogged Fixtures Sometimes, the issue lies in your faucets or showerheads. Dirt, debris, or limescale can clog fixtures, reducing the water flow. While this is often something you can fix yourself, it’s important to rule out more serious causes. Faulty Pressure Regulator If your water pressure is fluctuating or uniformly low, the pressure regulator might be faulty. This part ensures your water pressure remains at a safe, functional level, so any issues with it need immediate attention. Main Water Line Problems Sometimes, low water pressure originates outside your home. Damage to your main water line, aging utility infrastructure, or municipal water supply issues can affect overall pressure. When Should You Call A Rescue Rooter While some causes of low water pressure are simple enough to tackle on your own, others require the expertise of a professional. Here are some scenarios when calling a plumber—like Rescue Rooter in Southern Ontario—is your best bet: 1. You Can’t Find the Source of the Problem If you’ve checked for clogged fixtures, leaks, or a failing pressure regulator and can’t identify the issue, it’s time to call in the pros. A professional plumber has the tools and experience to diagnose the root cause quickly. 2. You Suspect a Hidden Leak Water leaks aren’t always obvious; they may occur behind walls, under floors, or in your outdoor plumbing. If your water pressure is dropping and you notice damp patches, unexplained water bills, or musty odors, a plumber should investigate immediately. 3. The Entire Home is Affected If the water pressure is low throughout the house (not just in one or two fixtures), this could be a sign of a larger issue, such as a damaged main water line or a problem with your pressure regulator. 4. There’s a Sudden and Significant Drop A sudden drop in water pressure can indicate a burst pipe or other significant damage. This requires immediate attention to prevent further harm to your home. 5.
