    I specifically asked for Mike again after he did such a great job on a previous repair and he handled our septic tank replacement with the same care and expertise. It means a lot when a company has technicians you can trust by name for major projects.

    Superior Plumbing did excellent septic tank replacement work at our property and the difference in drainage was immediately noticeable. Steve clearly has years of experience and his confidence showed in every step of the excavation. Top quality work.

    I called Superior Plumbing at 7 am after discovering a septic tank emergency and Rob arrived within 45 minutes to quote the replacement. He diagnosed the root cause immediately, explained every step before starting, and had the project scheduled before I left for work.

    Had an urgent septic tank replacement situation at 11 pm and could not believe someone actually answered the phone. Aaron arrived the same afternoon and resolved everything before the ground became too saturated. Competitive pricing and quality trade work.

    Septic Tank Replacement in Welland

    Like other devices, septic systems can stop functioning properly after a certain period of use. When sewage flows into your home or unpleasant odours come from the yard, it’s an indication that the septic tank has failed. Based on the cause of the problem, you’ll need to decide whether to book septic system installation or repair in Welland. Take a look at the most common problems:

    • Standing water. Standing water is a sign that the septic system is not able to properly dispose of water. This leads to bacterial growth. Contact Superior Plumbing & Heating to schedule a routine inspection and to arrange for a new septic system installation in Welland;
    • Frequent repairs. Regular maintenance is beneficial, however, if repairs are needed frequently, consider a complete septic tank replacementl;
    • Bad odours. Gases can enter your home through toilets, sewer pipes, and drainage fields. If they reappear after emptying the septic tank, it means that the device has failed and needs to be replaced;
    • Lash and green grass. Green grass is usually a good sign, but it can also indicate that your soil is being full with sewage. It is important to check for leaks;
    • Pipe backups. You should consider upgrading your system if you have to pump out septic tanks regularly and sewage is leaking through your toilet.

    If you encounter one of these problems, contact the experts at Superior Plumbing & Heating, who will determine the root of the problem and fix it before it becomes a disaster.

    Why and when should you repair the components of a septic tank?

    Superior Plumbing & Heating can meet your maintenance or replacement needs for a tankless septic system, aerobic system or anaerobic system in Welland. Most problems can be solved by replacing damaged components:

    Replacement of septic lines. Clogged or broken septic tanks can cause backups. We provide a full range of services to fix any problem. Septic tanks are installed from the house to the collection tank or from the septic tanks to the junction boxes.

    Replacement of the septic field. A septic field may need to be replaced due to poor maintenance, damaged components, improper installation, or because the soil has compacted for various reasons;

    Septic tank replacement. A faulty tank can cause stress on the rest of the system, leading to its failure. Depending on your needs, we offer a variety of septic tanks for plastic or concrete tanks;

    Replacement for the junction box. Damage to this part usually results from wear and tear, improper installation, or physical damage. Our septic system contractors in Welland are able to install the entire junction box within one day;

    Replacement of baffles in the septic tank system. Baffles in a septic tank are important components. When they fail, it can cause the system to fail. Inlet and outlet baffles are installed by Superior Plumbing & Heating.

    How long do septic tanks normally last?

    The type of septic tank affects its service life. A steel septic tank starts to rust, first by losing its baffles (which leads to a blocked drain field) and then eventually by rusting on the sides or bottom. If your tank is more than 15 years old, it is most likely already rusted. Concrete septic tanks have a longer lifespan, usually over 40 years. But this also depends on the acidity level of the soil surrounding the tank, as well as the quality of the materials used in the construction of the tank. Fibreglass and plastic septic tanks are equally durable and resistant to mechanical damage. Regular maintenance of the septic system can extend the life of your device.
