How To Unclog a Sink in 5 Easy Steps

Chelsey Smith • April 5, 2024

Dealing with a clogged sink is one of those household chores that seem to strike at the most inopportune times — like when you're running late in the morning, or during a bustling dinner party. The water takes ages to drain or, worse, it doesn’t drain at all. What do you do?


Whether it’s caused by excess hair, grease, or soap scum, a clogged sink is not only a nuisance but can also be a health hazard and lead to water damage if not managed promptly. But fear not, in this guide we'll walk you through the simple steps to take back control of your drain.


Understanding the Signs of a Clogged Sink

Before you roll up your sleeves, it's important to know the culprits. Pay attention to the signs — is the water draining slower than normal? Does it back up into the sink? Perhaps you hear gurgling sounds when the water is trying to go down.


These symptoms indicate you’re approaching a clog, or might already be there. Being proactive and addressing these issues promptly can prevent further damage.


Tools and Materials Needed

Unclogging your sink shouldn't require a PhD in plumbing. Basic tools and some easily obtainable materials are all you need. Here's what you should have ready:

  • A sink plunger
  • A plumber's snake/augers
  • Baking soda
  • Vinegar
  • Boiling water
  • Rubber gloves
  • A bucket
  • A sponge or cloth
  • Adjustable wrench (for P-trap removal)


Make sure you're familiar with the operation of these tools before you begin. Safety should always come first, especially when it involves sharp objects and hot liquids.


The Step-by-Step Guide


Step 1: Clearing the Area and Preparing the Sink

Before you start plunging or dismantling any parts, ensure the area is clear. Remove any objects from around the sink that could interfere with your work. If you've got a double-basin kitchen sink or one with a secondary container, block the unclogged portion with a stopper or a damp cloth to ensure proper suction when you plunge.


Step 2: Using a Plunger to Unclog the Sink

A sink plunger is slightly different from a toilet plunger — it has a flat bottom and a narrower profile. It's your first line of defense against a clog in most cases. Here's how to use it effectively:

  • Fill the sink with a few inches of water to create a seal around the plunger.
  • Position the plunger over the drain, ensuring it forms a tight seal.
  • Plunge up and down rapidly several times, maintaining the seal.
  • Check to see if the water begins to drain. If it doesn't, repeat the process a few times.


Step 3: Applying Natural Solutions for Unclogging

If plunging doesn’t do the trick, it’s time to switch to household remedies:

  • Pour a pot of boiling water down the drain to dissolve some of the blockage.
  • Create a mixture of one part baking soda to one part vinegar and pour it down the drain, using the solution's fizzing action to dislodge the clog. Afterward, pour hot water to flush it away.

Be patient with these solutions — they're often effective, but might need time to work, especially on tougher clogs.


Step 4: Checking and Clearing the P-Trap

The P-trap is the curved section of pipe under the sink. It’s common for it to collect debris over time. To clear the P-trap:

  • Place a bucket or pan under the P-trap to catch any water and debris.
  • Use an adjustable wrench to loosen the slip nuts that hold the P-trap in place.
  • Once removed, clear out any visible obstructions with a gloved hand or a long brush.
  • Reassemble the P-trap and run water to check if the problem is fixed.


Step 5: Preventing Future Clogs

The best way to cope with sink clogs is to stop them from happening in the first place:

  • Use strainers to catch hair and debris in the bathroom.
  • Never pour grease or oils down the kitchen sink — always dispose of them in the trash or collect them for recycling.
  • Regularly flush your drains with hot water to prevent build-up.


When to Call a Professional

Sometimes, despite your best efforts, a clog may be deep in the pipes or there could be a more serious issue at play. If you're dealing with recurrent clogs, if multiple sinks are affected, or if you’ve tried several methods with no luck, it might be time to call in a professional Hamilton plumber.

Winter brings cozy nights and festive cheer, but it also carries the risk of a messy and expensive household problem: frozen pipes. When water freezes, it expands, putting immense pressure on your plumbing. This can lead to burst pipes, significant water damage, and costly repairs. Understanding how to protect your home before a cold snap and what to do if a pipe freezes is essential for every homeowner. Proactive Steps to Prevent Frozen Pipes The best way to deal with a frozen pipe is to prevent it from ever happening. A little preparation before temperatures plummet can save you a lot of stress and money. Focus on areas of your home where pipes are most vulnerable, such as basements, crawl spaces, attics, garages, and exterior walls. Insulate Vulnerable Pipes Insulation is your first line of defense. It slows the transfer of heat, keeping the water inside your pipes from reaching freezing temperatures. Pipe Sleeves: You can find foam or fiberglass pipe sleeves at any hardware store. They are inexpensive and easy to install. Simply cut them to size and wrap them around exposed pipes. Secure them with tape for a snug fit. Heat Tape: For pipes in extremely cold areas, consider using electrical heat tape or heat cables. These products wrap directly around the pipe and have a built-in thermostat that turns the heat on when the temperature drops, providing consistent protection. Seal Air Leaks: Cold air infiltration is a major contributor to frozen pipes. Use caulk or insulation to seal any cracks or holes in your foundation, walls, and around windows, especially where pipes enter your home from the outside. Keep the Water Moving Even a small trickle of water can be enough to prevent a pipe from freezing solid. When an arctic blast is in the forecast, take these simple steps. Let Faucets Drip: Open the faucets connected to vulnerable pipes just enough to let a slow, steady drip of both hot and cold water flow. This moving water is much harder to freeze. Open Cabinet Doors: Pipes under kitchen and bathroom sinks are often located in unheated cabinets against exterior walls. By leaving the cabinet doors open, you allow warmer air from your home to circulate around the plumbing, keeping them warmer. Maintain a Consistent Temperature Your home's overall temperature plays a crucial role in protecting your plumbing system. Set Your Thermostat: Keep your thermostat set to a consistent temperature both day and night. While you might be tempted to lower it at night to save on heating bills, the extra cost is minimal compared to the expense of a burst pipe repair. Winterizing Your Home: If you plan to be away for an extended period during the winter, never turn your heat completely off. Set the thermostat to at least 55°F (13°C) and consider asking a friend or neighbor to check on your house periodically. What to Do If Your Pipes Freeze Sometimes, despite your best efforts, a pipe may freeze. The first sign is usually a trickle of water—or no water at all—coming from a faucet. If you suspect a frozen pipe, you need to act quickly. Step 1: Locate the Frozen Pipe Your first task is to identify the frozen section of pipe. Start by turning on all the faucets in your house. If one is not working, the frozen area is likely located between that faucet and the main water supply. Look for pipes in unheated areas or along exterior walls. A visible layer of frost or a slight bulge in the pipe can also indicate a freeze. Step 2: Thaw the Pipe Safely Once you've found the frozen section, you can begin the thawing process. The key is to apply heat gradually and safely. Open the Faucet: Before you start thawing, make sure the faucet connected to the frozen pipe is open. This allows melting water and steam to escape, relieving pressure inside the pipe. Apply Gentle Heat: Use a hairdryer on a low setting, a portable space heater (kept a safe distance away), or heating pads designed for this purpose. Start near the faucet end of the blockage and work your way back toward the frozen area.  Never Use an Open Flame: Do not use a blowtorch, propane heater, or any other open-flame device to thaw a pipe. This is extremely dangerous, as it can damage the pipe and create a serious fire hazard. Step 3: Check for Leaks As the pipe thaws, water flow should be restored. Keep a close eye on the entire length of the pipe you just thawed. The expansion from the ice may have created cracks that will begin to leak as the water melts. If you spot a leak, shut off the main water supply to your home immediately to prevent water damage. When to Call a Professional While some minor freezes can be handled on your own, certain situations require expert intervention. A burst pipe is a plumbing emergency that demands immediate professional help. If you are unable to locate the frozen pipe, if the pipe is not accessible, or if your efforts to thaw it are unsuccessful, it’s time to call for help. Attempting complex repairs without the right tools or experience can lead to bigger problems.

A small drip from a faucet is easy to spot, but what about the leaks you can't see? Hidden water leaks can silently cause significant damage to your home’s structure, promote mold growth, and lead to shockingly high water bills. Knowing how to spot the signs of these elusive leaks is a crucial skill for any homeowner. This guide will walk you through practical methods for detecting hidden water leaks and explain why acting fast is so important. Why You Must Address Leaks Immediately Ignoring a potential water leak is a gamble you don't want to take. Even a small, slow drip can have major consequences over time. Water can weaken wooden beams, crumble drywall, and damage your home's foundation. The persistent moisture creates a perfect environment for mold and mildew, which can pose health risks to your family. Beyond structural damage, the financial cost is twofold. First, your water bill will increase as you pay for water you aren't even using. Second, the repair costs for water damage are often far more expensive than the cost of fixing the leak itself. A simple plumbing repair can turn into a massive renovation project if left unchecked. Simple Ways to Find Hidden Leaks You don't need to be a professional plumber to start the search for a hidden leak. With a little observation and a few simple checks, you can often identify a problem before it gets out of hand. Check Your Water Meter Your water meter is one of the most reliable tools for leak detection. It measures all the water flowing into your home, so any unexpected activity can point to a leak. How to perform a meter test: 1. Turn off all water: Make sure no faucets are running, toilets aren't flushing, and appliances like the dishwasher or washing machine are off. 2. Locate your water meter: It's usually in a box near the curb or in a basement or utility area. 3. Check the leak indicator: Most modern meters have a small triangle, dial, or wheel that moves when water is flowing. If this indicator is spinning, even slowly, you likely have a leak somewhere in your system. 4. Note the reading: If your meter doesn't have a leak indicator, write down the numbers on the dial. Wait one to two hours without using any water, then check the reading again. If the numbers have changed, water is escaping somewhere. Scrutinize Your Water Bill Your monthly water bill provides a clear record of your usage. A sudden, unexplained spike is a major red flag. Compare your recent bills to previous months or the same period from last year. If your habits haven't changed but your usage has dramatically increased, it’s time to investigate. Many utility companies even provide daily or hourly usage data online, which can help you pinpoint when the excess water use is happening. Inspect Your Home's Interior Your walls, ceilings, and floors can offer visual clues of a hidden leak. Take a walk through your home and look for these signs: ● Discoloration or Stains: Yellow or brown stains on ceilings or walls are classic signs of water slowly seeping through. ● Peeling or Bubbling Paint: Moisture behind a wall will cause paint or wallpaper to peel, bubble, or blister. ● Warped Surfaces: Look for warped walls, sagging ceilings, or buckled flooring, especially around bathrooms, kitchens, and laundry rooms. ● Musty Odors: A persistent damp, earthy smell often indicates mold or mildew growth, which thrives in areas with hidden moisture. Listen for Unusual Sounds Sometimes, you can hear a leak before you can see it. During a quiet time in your home, like late at night, listen carefully for sounds coming from your walls. A dripping, hissing, or rushing sound when all faucets are off is a clear signal that water is running where it shouldn't be. Pay close attention to the areas where your main water line enters the house and around major plumbing fixtures. Don't Wait—Get Professional Help Finding a hidden leak can feel overwhelming, but you don't have to handle it alone. While these DIY tips can help you confirm a problem exists, locating the exact source and repairing it often requires professional expertise and equipment.
