    Tyler completed our toilet repair and was very patient with my elderly mother. He explained exactly what was done to the fill valve and why. 10 out of 10 service from a very kind technician.

    I manage a small restaurant and a toilet failure during service is catastrophic. Superior Plumbing sent Sean in under an hour and he worked quickly without disrupting our kitchen or guests. Reliable service.

    We have used Superior twice for toilet repairs and both times were excellent. Dan remembered the details of our older plumbing and gave us great preventive maintenance advice. Rare continuity.

    Our toilet broke down on a Friday evening. Jason came by early afternoon the next day and fixed the problem at a perfectly standard rate. They offered a payment plan that fit my budget. Very reasonable.

    How to fix a running toilet in St. Catharines?

    A running toilet isn’t just noisy and annoying; it also means you’re spending more money on your water bill. The following are the most typical issues with toilets you might run into:

    • Faulty float. This element determines how full the toilet tank is; if it is defective, the toilet will not work. If the water continues to flow after trying to fix the float, call a professional to help you solve the problem quickly and once and for all.
    • Blockage. If the toilet is clogged, there may be nowhere for the water and debris to drain, so the toilet will continue to flush. If no attempts to unclog the toilet have worked, we recommend calling a toilet plumber in St. Catharines.
    • The refill tube is too long. Another reason for running a toilet may be continuously pumping the water refill tube. This happens when it is too long, but to shorten it, consult an expert, as it can be problematic without the necessary tools.

    Before you decide to repair your plumbing yourself, think again because, depending on the type of toilet (two-piece, one-piece, American standard, double flush, wall mounted, etc.), the above problems require different repair methods. Therefore, if you do not have sufficient experience and professional tools, the most effective and reliable way to fix your toilet is to call our skilled plumbers in St. Catharines. Superior Plumbing & Heating will do whatever it takes to make your problem disappear, so you’ll forget it ever existed!

    How much does it cost to repair a toilet in St. Catharines?

    When something goes wrong with the toilet, your first thought is, “how to fix it ASAP, and how much will it cost.” Several factors can affect the price of repairs, and here they are:

    • Toilet features. The more “advanced” the features, the more expensive your toilet repair will be. If you need to repair a toilet with custom height/colors or pressure-assisted flushing, it will be more expensive to fix than a basic toilet.
    • The seriousness of the problem. If you have a small toilet tank leak, it’s usually cheaper to fix than more severe damage, such as a leaking toilet bowl or continuous flushing.
    • Additional work. If, in addition, you need plumbing modifications, replacing the toilet, dismantling it, installing additional parts, etc., this will also affect the cost.
