    I called Superior in Trenton, ON very late this Monday night after discovering a cracked and leaking pipe in my basement (but on the wrong side of the shutoff valve), just after calling the city hotline to get the water shut off from the valve under our lawn. I had to leave a voicemail with Superior as it was after hours, but they were prompt to respond the next morning, sent one of their plumbing inspectors out to inspect the issue before 10AM, gave me a quote on the spot and said a team would be back between 6 and 8 that evening to do the repairs. As luck would have it, an earlier appointment opened up, and the team came in early at 2PM, and were all done by 3. They had even recommended I call the city ahead of their arrival to make sure someone could come back to turn the water back on before Superior’s team left. The parts they replaced exactly matched what the early inspector informed me was most likely, and the final bill was spot on to the cent of the morning’s estimate. I would hightly recommend Superior to anyone needing plumbing work done, and will 100% work with them again in the future.

    septic replacement service London

    Septic tank replacement is one of the multiple services Superior Plumbing & Heating plumbers provide in London, Ontario. Thus, our company offers high-quality services for residential buildings and commercial premises right on the day of the client’s request.

    What Are the Main Signs of Septic Tank Failure?

    Even though a septic tank can serve you for up to 40 years with proper maintenance, it is not immune to breakdowns. So, consider contacting specialists to inspect, fix, or replace the septic tank in London Ontario, if you notice the following failure signs:

    • Backup. When the septic system is overfilled or damaged, sewage stops flowing into the tank. In other words, wastewater accumulates in pipes and rises up afterward. Backup is one of the most apparent signs of a malfunction that requires quick solutions from specialists.
    • Gurgling. The gurgling noise from plumbing appliances requires your attention as it indicates blockages in the septic system. But clogs will never lead to backups if you invite experts for diagnostics in time.
    • Dampness in the drain field area. The inability of the septic tank to absorb sewage due to a breakdown provokes water seepage to the outside. As a result, you may notice dampness or even puddles in the drainage field area. So, if it hasn’t rained for several days, but you detect dampness, your septic tank needs inspection.
    • Foul odor. Another reason you might need a septic tank replacement service or repair in London is the nasty smells from plumbing appliances or near the drainfield. It indicates that the septic tank has failed, and sewage has filled the drainage field, ending up in the main sewer line.
    • Slow draining. When the septic tank is full, sewage fills the pipes. Thus, the wastewater from your plumbing fixtures cannot drain sufficiently, resulting in a slow drain. It is worth noting that slow drains are an alarming sign, foreshadowing the septic tank overflow and the further return of wastewater to your home.

    Superior Plumbing & Heating plumbers are preeminent experts in replacing a septic tank in London Ontario. We use only reliable equipment and technology to make your septic system last longer.

    How Often Should You Replace a Septic Tank?

    As mentioned, a septic system can last many years with proper maintenance and regular pumping. Another influencing factor is the material from which the pipes are made and their condition. Therefore, if you need to check them, contact our plumbers and ensure the pipes are not rusty. The specialist may suggest that you replace the old sewer lines with HDPE or PVC pipes since they are almost indestructible with proper handling.

    You can trust our team if you need to replace the septic tank or find reliable maintenance specialists. In addition to the high quality of work, Superior Plumbing & Heating customers enjoy our septic tank replacement cost, which is one of the most affordable in London Ontario.
