    Bruce was amazing!! We had a leak in the kitchen and could not figure it out. Bruce checked it, fixed it, and repeatedly checked it before leaving. Price was fair, and so convenient to have service on Saturday. Helped us with our hot water line also that was not running well. Gave us some advice about our hot water heater also! Went above and beyond!!

    Called at 930am. Plumber shows up at 1030am. honest + amazing + affordable. Person handling the phone deserve much praises too on picking up the phone within 2 rings, and manage to take down details quickly and assign the work order fast. Alvin ( sorry if I didn’t spell it right ), was great. came to my place, saw the issue, solved it without any hiccups.

    Our plumber told us we needed an expansion tank for our new water heater to protect our pipes from pressure buildup. Conner installed it quickly, explained why it was important, and made sure everything was working properly before leaving. Really impressed with his attention to detail!

    Hunter did an amazing job replacing our AC! He was professional, knowledgeable, and made the entire process smooth and stress-free. The installation was done perfectly, and our home is now cool and comfortable. He took the time to explain everything and ensured the system was running efficiently before leaving. Highly recommend Hunter for any AC work!

    Trustworthy toilet repair service in London

    Even though toilets are durable plumbing fixtures and last for years, they are not immune to breakage. Undoubtedly, this is one of those breakdowns that brings the most inconvenience. But fortunately, all you need to do is to google “toilet repair plumber near me” and find reliable plumbers. So from now on, the repair of your toilet goes into the experienced hands of specialists.

    Our company, Superior Plumbing & Heating, is ready to offer you all types of repairs, including the most complex ones. In addition to decades of extensive experience, our team employs advanced diagnostic and repair technologies, distinguishing us from others and benefiting customers. With us, you can count on a flexible appointment schedule and advanced price system.

    Why is your toilet broken?

    Check the most common toilet breakdowns and effective ways to fix them on your own or with the help of our top toilet repair service in London.

    Water leaks

    This breakdown also requires a quick solution since a leak can have serious consequences and pose a health hazard if it is wastewater.

    The most common places for leaks are:

    • The toilet’s base
    • The water supply line connection
    • The nut behind the valve
    • The loose tank-to-bowl kit

    If the cause is in the toilet’s base, the repair requires replacing the wax ring, for which you need the help of someone strong who can lift a toilet. As for worn parts, you need to buy the same but new ones and replace them. Finally, if the source of the leak is a loose nut, tighten it.

    Non-stop running

    To find out why the toilet is constantly running, wasting gallons of water a day, remove the tank lid and check the following:

    • Overflow valve
    • Flush valve
    • Flapper chain
    • Toilet handle

    If all these parts are undamaged, test the flapper by pressing on its edges. If the toilet stops running, it indicates a loose seal and the need to replace the flapper. Call our specialists to study the problems and find the best repair solution.

    Whooshing, vibrations, or whistling

    Sometimes the toilet makes one or more of these sounds when not in use. A minor cause may be a plumbing pipe blockage, which you can fix with a plunger. A more severe problem is a faulty ballcock or flush valve.

    Suppose you don’t know how to find a broken part or replace it. In that case, you should contact a specialist as soon as possible because your toilet sounds entail a higher water bill due to the changing water level in the tank.

    Whatever your toilet problem may be, our reliable and experienced toilet plumber is available 24/7 for clients in London and many other locations. Therefore, entrust the repair task to our Superior Plumber & Heating if you are better at baking cakes than plumbing.

    How to repair a running toilet in London, Ontario?

    As already mentioned, a running toilet is one of the most common problems caused by damaged parts. And while broken flapper replacement requires little time and no specialized tools, other malfunctions are more challenging.

    If you still decide to repair yourself, remember that it is essential to find the cause first. Then, when you know which parts to change, you should choose those compatible with your toilet and good quality. Otherwise, the fix will only last for a while, and you’ll have to do it all over again.

    But the most efficient and reliable way to fix a toilet in London Ontario is to contact professional plumbers. For example, if you become our client, you get the following benefits:

    • Same-day reliable repairs with a 90-day quality guarantee
    • Full-licensed plumbers with decades of experience
    • Thorough and high-quality diagnostics
    • Only original spare parts
    • Reasonable price without extra charges

    What people in London ask about toilet repair most often?

    How to replace the toilet seat?

    Replacing a toilet seat is a simple DIY project that can be completed in a matter of minutes. Here’s a basic guide:

    1. Shut off the water. Shut off the water supply to the toilet tank to prevent accidental leaks.
    2. Unscrewing nuts. Using a special tool (wrench or ratchet), specialists carefully unscrew the nuts that secure the old seat to the bolts.
    3. Removing the seat. After unscrewing the nuts, the seat is carefully removed to avoid damage to the toilet bowl or debris.
    4. Clean the surface. Wipe down the surface around the bolt holes to remove any dirt or debris.
    5. Attach the new seat. Align the new seat with the bolt holes and gently press down. Tighten the nuts securely, but avoid overtightening.

    If you encounter any difficulties or need assistance with a larger plumbing project, please contact us today!

    What to do if the toilet tank is constantly filled with water?

    A toilet tank that is constantly filled with water is likely due to a faulty fill valve or flapper. Here’s what you can do:

    • Turn off the water supply. Locate the water supply valve behind the toilet and turn it clockwise to shut off the water.
    • Flush the toilet. Flush the toilet to remove any excess water from the bowl.
    • Check the flapper. Inspect the flapper for any signs of wear, damage, or debris. If the flapper is not sealing properly, it may need to be replaced.
    • Check the fill valve. The fill valve controls the water level in the tank. If it’s malfunctioning, it may be causing the tank to overfill.

    While you can try to fix the issue yourself, it’s often best to call a professional plumber.

    What to do if the toilet does not flush well?

    A toilet that doesn’t flush well can be a frustrating issue. Here are a few possible causes and solutions:

    • Clog. If it seems like nothing is going down, you likely have a clog. Try using a plunger to clear the blockage. If that doesn’t work, a plumbing snake might be necessary.
    • Weak flush. A weak flush could be caused by a clogged toilet, a problem with the water supply, or a worn-out flapper. Check the water level in the tank and the flapper for any issues.
    • Old toilet. If your toilet is quite old, the internal components may be worn out, leading to poor flushing.

    If you’re unable to resolve the issue yourself, contact a professional plumber. Superior Plumbing & Heating offers expert toilet repair services in Mississauga. We can diagnose and fix the problem quickly and efficiently.
