How to Use a Plunger Properly

Chelsey Smith • April 2, 2026

When a drain backs up, panic often sets in—but before you reach for harsh chemicals or call it a lost cause, a simple plunger can often do the trick. Knowing how to use the right type of plunger—and how to use it correctly—can save you time, money, and stress. In this guide, we’ll walk you through how to use both toilet and sink plungers effectively, and when it’s time to call in the professionals at A Rescue Rooter in Southern Ontario.

Types of Plungers (And Why They Matter)

Toilet Plunger (Flange Plunger)

A toilet plunger is designed with a soft rubber flap (or flange) that extends from the cup. This allows it to create a tighter seal inside the curved toilet drain.

Best for: Toilets only
Why it works: The flange fits snugly into the drain opening, creating the suction needed to dislodge clogs.


Sink Plunger (Cup Plunger)

The sink plunger has a flat bottom without a flange, making it ideal for flat surfaces like sinks, tubs, and shower drains.

Best for: Sinks, bathtubs, and floor drains
Why it works: The flat cup forms a seal over flat drain openings.


How to Use a Toilet Plunger

Using a plunger properly is just as important as having the right one. Follow these steps for best results:

  1. Ensure There’s Enough Water
    The plunger cup must be fully submerged to create effective suction. Add water to the bowl if needed.
  2. Position the Plunger Correctly
    Insert the flange into the toilet drain opening and press down gently to create a seal.
  3. Start Slowly
    Begin with gentle pushes to remove trapped air. This prevents splashing.
  4. Plunge with Force
    Once sealed, plunge vigorously up and down for about 15–20 seconds. Maintain the seal throughout.
  5. Test the Drain
    Pull the plunger away and see if the water drains. Repeat if necessary.

Pro Tip: Avoid aggressive first plunges—this can cause messy splashes instead of effective suction.

How to Use a Sink Plunger

  1. Block the Overflow Hole
    Most sinks have an overflow opening. Cover it with a wet cloth or tape to improve suction.
  2. Add Water if Needed
    Just like with toilets, the plunger cup needs to be submerged.
  3. Create a Seal
    Place the plunger directly over the drain and press down to remove air.
  4. Plunge Steadily
    Use quick, consistent plunges for 15–30 seconds.
  5. Check Drainage
    Remove the plunger and test the water flow.


Common Mistakes to Avoid

  • Using the wrong plunger type
  • Not sealing the plunger properly
  • Plunging too aggressively at first
  • Forgetting to block overflow drains in sinks
  • Giving up too quickly (sometimes it takes a few rounds)

As the snow melts and the first green shoots of spring appear, it feels natural to breathe a sigh of relief. The harsh winter is finally behind us, and warmer days are ahead. However, while you are ready to welcome the sunshine, your home’s plumbing system might be facing its most difficult challenge of the year.  The transition from freezing winter temperatures to the damp warmth of spring creates specific environmental changes that can stress your pipes. Understanding what happens beneath the ground during the "spring thaw" is the first step in protecting your home from unexpected leaks and water damage. By staying vigilant and knowing what to look for, you can ensure your plumbing transitions into the new season as smoothly as you do. How the Spring Thaw Affects Your Plumbing It is easy to assume that the danger to your pipes passes once the sub-zero temperatures vanish. In reality, the thawing process can be just as damaging as the freezing process. When the ground freezes, it expands. As it thaws, the soil contracts and shifts. This movement can put immense pressure on your home's water and sewer lines buried underground. If the earth shifts too dramatically, it can cause pipes to crack, bend, or even detach completely. Additionally, the spring thaw brings water—lots of it. Melting snow saturates the soil, raising the water table. This excess water puts hydrostatic pressure on your foundation and pipes, potentially leading to basement flooding if your drainage systems aren't working perfectly. Common Signs of Pipe Damage Because much of your plumbing is hidden behind walls or buried underground, you might not notice an issue until it becomes a significant problem. Keep a close eye on your property this season for these tell-tale signs of distress: 1. Soggy patches in the yard If it hasn't rained recently, but you notice distinct wet, spongy, or unusually green patches of grass in your yard, this could indicate a leak in your underground water line. The escaping water rises to the surface, creating a localized swamp. 2. Low water pressure A sudden drop in water pressure throughout the house is often a symptom of a breach in the main line. If the water isn't reaching your faucets with the usual force, it may be escaping somewhere else along the route. 3. Unpleasant odors If your sewer line has been compromised by shifting soil or infiltrating tree roots (which become active in spring), you may smell sewage inside your home or out in the yard. This is an urgent issue that requires immediate attention. 4. Unexpectedly high water bills Sometimes the signs are financial rather than physical. If your water usage hasn't changed but your bill has spiked, water is likely leaking from a pipe somewhere on your property. Preventive Measures for Homeowners While you cannot control the weather or the shifting soil, there are several steps you can take to minimize the risk of damage during the spring thaw. Test your sump pump: This is your first line of defense against meltwater. Pour a bucket of water into the sump pit to ensure the pump activates and drains the water effectively. If it doesn't, you need to repair or replace it before the heavy spring rains arrive. Clear your gutters and downspouts: Ensure that melting snow and spring rain can flow freely away from your home’s foundation. Clogged gutters can cause water to pool around the base of your house, increasing pressure on basement pipes and the foundation. Check outdoor faucets: Once the threat of frost is truly gone, turn on your outdoor spigots to check for flow. If you place your thumb over the opening and can stop the flow of water, the pressure is too low, indicating a potential leak inside the pipe. When to Call the Professionals Plumbing issues can be stressful, and it is often difficult to know if a problem is a simple DIY fix or a professional emergency. We understand that your home is your sanctuary, and dealing with water damage is disruptive and upsetting. If you notice persistent low pressure, damp spots on your drywall, or standing water in your yard, it is time to call for help. Attempting to dig up underground pipes or fix complex sewer lines on your own can often lead to further damage and higher costs. At Rescue Rooter, we have the specialized equipment to inspect underground lines without destroying your yard. Our team can identify cracks caused by the spring thaw and provide efficient, lasting solutions. We are here to help restore your peace of mind so you can get back to enjoying the warmer weather. Enjoying a Worry-Free Spring Spring should be a time of renewal and enjoyment, not a time spent worrying about wet basements or broken pipes. By keeping an eye out for the signs of shifting soil and testing your drainage systems early, you can catch small issues before they become major headaches. And remember, if the thaw does bring unexpected plumbing challenges, you don't have to face them alone—Rescue Rooter is just a phone call away.
