Diagnose the problem by assessing any water or sound coming from the toilet


When you notice strange sounds or water coming from your toilet, it can be concerning. Fortunately, this can be a sign of a minor issue that can be easily identified and repaired. To diagnose the problem, start by checking the water level in the tank and the bowl. If the water level in the tank is too high or too low, adjust it accordingly. Check to make sure the flapper is properly sealing the drain and not allowing water to escape. Additionally, check the fill valve and float to ensure they are not damaged or malfunctioning. With a little troubleshooting, you can solve the issue and restore your toilet's normal operation.


Shut off the water supply to the
toilet and flush it to drain out any remaining water


When it comes to fixing a toilet, shutting off the water supply and flushing it to drain out any remaining water is an essential step. Not only does it make the process less messy, but it also reduces the risk of any accidental spillage. Too often, small repairs are botched due to improper preparation, leading to bigger (and costlier) problems down the line. Taking the time to properly shut off the water supply and flush the toilet is a quick and easy way to ensure a successful repair. So, the next time you're faced with a wobbly or leaky toilet, don't skip this crucial step!


Disassemble the tank by removing the lid and flapper valve


Taking apart a tank may seem like a daunting task, but with a little know-how it can be done efficiently and quickly. The first step is to remove the lid and flapper valve. This may require some strength, but it's important to be careful not to damage any surrounding parts. Once the lid and flapper valve are removed, you'll have access to the tank's inner workings. With a better view, you can now identify any potential issues and work to fix them. Disassembling a tank may seem intimidating, but with a methodical approach, it can be accomplished with ease.


Clean the flapper valve with a brush and soap, then reinstall it


A properly functioning flapper valve is essential for a toilet to work effectively. If you are experiencing trouble with your toilet flushing correctly, it might be time to give your flapper valve some attention. The good news is that this is a simple fix that you can do yourself. To clean the flapper valve, start by removing it from the toilet and gently scrubbing it with a brush and some soapy water. Be sure to remove any debris or buildup that might be interfering with the valve's operation. Once it is clean, simply reinstall the valve and test your toilet to see if it is flushing properly again.  With just a little bit of effort, you can have your toilet working like new again in no time!


Replace any broken pieces such as a gasket seal or flush handle


When it comes to maintaining your toilet, it's important to replace any broken pieces as soon as possible to avoid any further damage or issues. Whether it's a faulty gasket seal or a broken flush handle, it's crucial to address the problem promptly. A faulty gasket seal can result in leaks or even mold growth, while a broken flush handle can make it difficult to properly flush waste away. By taking the time to replace any broken pieces, you can ensure that your toilet functions properly and avoid any potential costly repairs down the line.


Refill the tank with freshwater and test to make sure it's running properly


There's nothing quite like the satisfaction of a job well done, especially when it comes to something as important as your water tank. It's crucial to keep it in good condition to ensure that you have clean and safe water for you and your family. After you've emptied and cleaned your tank, it's time to refill it with fresh water and do a test run to make sure everything is functioning properly. This step is essential in guaranteeing that your system is working at its full potential. By taking these proactive measures, you can rest assured that your water quality is up to par, and you'll be able to enjoy crystal-clear H2O all year round.



Whether your toilet is making strange noises or just not working properly, you should be able to identify and address the most common toilet problems. Taking a few simple steps towards troubleshooting the problem such as shutting off the water supply, flushing, disassembling and cleaning, replacing broken parts, and refilling with fresh water can help get your toilet back up and running again.

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.
