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)

Summer is in full swing, the kids are home, guests are visiting, gardens are thriving, and your home's plumbing system is likely working harder than it has all year. While most homeowners think about plumbing problems during freezing winter weather, mid-summer can bring its own unique set of challenges. Being aware of common seasonal plumbing issues can help you avoid costly repairs and unexpected emergencies. If you notice signs of trouble, the experienced team at a Rescue Rooter is available to help homeowners throughout Hamilton with fast, professional plumbing services. 1. Clogged Kitchen Drains Summer often means more family gatherings, backyard barbecues, and outdoor entertaining. Unfortunately, all that extra cooking can wreak havoc on your kitchen sink. Grease, cooking oils, coffee grounds, vegetable peels, and food scraps can gradually build up inside your drains. Even if everything appears to be flowing normally, partial blockages can quickly become complete clogs. To help prevent problems: ● Never pour grease down the sink. ● Use drain strainers to catch food particles. ● Run plenty of cold water when using your garbage disposal. 2. Sewer Line Problems Tree roots are especially active during the warm summer months as they search for moisture. Tiny cracks in underground sewer lines can attract roots, eventually leading to blockages, slow drains, unpleasant odours, or even sewage backups. Warning signs include: ● Multiple slow drains throughout the home ● Gurgling toilets ● Water backing up into tubs or showers ● Sewage smells inside or outside your home Professional camera inspections can identify these problems before they become major repairs. a Rescue Rooter offers camera inspections, drain cleaning, hydro flushing, and sewer services for homeowners in Hamilton. 3. Washing Machine Overload With kids home from school, vacations, camping trips, sports, and swimming, many families find themselves doing far more laundry than usual. Extra loads place added strain on: ● Water supply hoses ● Drain lines ● Shut-off valves ● Washing machine connections Inspect hoses regularly for cracks, bulges, or leaks. Replacing an aging hose is far less expensive than cleaning up water damage from a burst line. 4. Outdoor Faucet Leaks Garden watering, pressure washing, filling pools, and washing vehicles all increase demand on outdoor faucets. Watch for: ● Dripping hose bibs ● Low water pressure ● Water pooling around exterior walls ● Leaks where hoses connect Small leaks may seem insignificant but can waste hundreds of litres of water over the course of a summer. 5. Sump Pump Issues Summer thunderstorms can dump large amounts of rain in a short period of time. If your sump pump hasn't been tested recently, you may not discover a problem until your basement begins taking on water. It's a good idea to: ● Test the pump before heavy storms arrive. ● Ensure the discharge line is clear. ● Remove debris from the sump pit. ● Consider a battery backup for power outages. 6. Water Heater Trouble Although your water heater works less during the summer, sediment buildup doesn't take a vacation. Signs your water heater may need attention include: ● Inconsistent hot water ● Strange rumbling noises ● Rust-coloured water ● Water leaking around the tank Routine maintenance can improve efficiency and extend the life of your water heater. 7. Hidden Leaks Summer vacations can leave homes sitting empty for days or even weeks. A small plumbing leak can become a major problem while you're away. Before leaving: ● Check under sinks. ● Inspect toilets for leaks. ● Turn off the main water supply if practical. ● Ask someone to check your home if you'll be away for an extended period. Don't Ignore Small Plumbing Problems One dripping faucet or one slow drain may not seem urgent, but small issues often become much larger—and much more expensive—when ignored. Mid-summer is an excellent time to inspect your home's plumbing before busy fall schedules return.
