    Tyler from superior plumbing and heating was great. He came to check out my leaking shower. Turns out it was a leaking P-trap. He ended up replacing it and now I’m leak free. Quick, and good pricing

    A burst pipe in the basement late at night could have turned into a disaster, but Superior Plumbing & Heating responded quickly. Tyler arrived within an hour and immediately assessed the damage. He repaired the pipe efficiently and carefully checked nearby connections to prevent further issues. He also gave helpful advice on insulation to avoid future freezing. The quick action likely saved me from major water damage.

    septic replacement service St. Thomas

    Septic Tank Replacement in St. Thomas

    Like many other systems, septic systems can cease to function correctly after years of usage. If sewage has backed up into your house or unpleasant smells are evident in your backyard, it’s a sign that your septic system has failed. It is necessary to make a decision about septic system installation or repair in St. Thomas depending on the cause. Let”s take a look at the most commonly encountered issues:

    • Standing water. This means that your septic tank is unable to properly eliminate water, leading to bacterial growth. Contact Superior Plumbing & Heating to schedule a routine inspection and arrange for a new septic installation in St. Thomas.
    • Frequent repairs. Regular maintenance is beneficial, but if repairs are needed frequently, consider replacing the septic tank.
    • Unpleasant odours. Gases can enter your home through sewers, toilets, or drainage fields. If gases return after flushing your septic system, it is likely that your unit has failed and you will need to replace it.
    • Lash and green grass. Green grass is usually a great sign, but it can also be a signal that your soil has been enriched with sewage. It is important to check for leaks.
    • Pipe backups. Consider upgrading the system if you have to pump out septic tanks frequently and sewage flows through the toilet.

    Contact Superior Plumbing & Heating if you are experiencing any of these problems. We will determine the cause of the problem and fix it quickly before it escalates into an inevitable disaster.

    Why and when should you fix the components of the septic tank?

    Superior Plumbing & Heating can solve your problems with the repair or replacement of a tankless septic system, aerobic system or anaerobic system in St. Thomas. Most problems can be solved by simply replacing damaged components:

    Re-installation or repair of the septic line. Backups can result from broken or clogged septic pipes. Fortunately, septic lines can be repaired from the house to the septic tank that collects the wastewater, from the septic tank to the junction box and replacing the septic tank side. We offer a wide range of solutions to any problem.

    Replacement of the septic field. The septic field in your home may need to be replaced due to poor maintenance or damaged components, improper installation, or because the soil has become more compacted for various reasons.

    Repair of a septic tank. A faulty tank can put stress on the rest of your system and cause it to fail. We offer concrete or plastic septic tanks to suit your needs.

    Replacement of junction box. Damage to this part of the equipment is usually caused by wear and tear, improper installation or physical damage. Our septic system contractors in St. Thomas will gladly install the entire junction box in one day.

    Repairing baffles on a septic tank system. The baffles in your septic tank are important components, and if they are damaged, they can cause the system to fail. Both outlet and inlet baffles can be installed by Superior Plumbing & Heating efficiently!

    How long do septic tanks typically last?

    The type of tank can also affect its service life. Septic tanks made of steel begin to rust sooner. They begin to lose their baffles (which leads to clogged drain fields) and then rust on the sides or bottom. If your tank is 15 to 20 years old or more, chances are it’s rusted. Concrete septic tanks have a longer service life, usually over 40 years. However, it also depends on the acidity of the soil around the tank, as well as the quality of the materials used in the construction of the tank. Septic tanks made of plastic and fibreglass are durable. Mechanical damage is the only exception. Regular cleaning of the septic tank will extend its service life significantly, so don”t neglect it!

    What makes Superior Plumbing & Heating Unique?

    Not sure if you should change your septic system? At Superior Plumbing & Heating, you can get in touch with septic tank installers. All of our highly-trained septic field installers in St. Thomas are prepared and have all the necessary tools on their vehicles.
