Your Local Licensed Experts: Trusted, Experienced, and Efficient
Many older homes in Toronto still have outdated underground main water lines made of lead or narrow copper piping, often with a diameter of just half an inch. These aging pipes not only cause poor water pressure but also pose serious health risks, especially if they’re made of lead. Lead contamination is now recognized as a significant health hazard. Upgrading these old water service lines is a complex task that requires digging and expert handling, and it must be done by licensed professionals.
At our Toronto plumbing service, our certified and highly skilled team specializes in trenchless water service line replacement using advanced torpedo drilling technology. Over the past 20 years, we’ve helped thousands of homeowners improve their water pressure, eliminate lead contaminants, and replace leaking or burst underground pipes. Compared to traditional trenching, our trenchless method offers numerous benefits, including minimal disruption to your property. Ready to upgrade your water line?

How Our Trenchless Torpedo Method Works
Our trenchless torpedo technology uses a powerful, four-foot-long cylinder mechanism powered by compressed air. This device works similarly to a jackhammer, creating a new tunnel for the upgraded water line with minimal digging. The process requires just two small access points: one inside the home near the water meter (typically located in the basement) and another outside near the property line.
• Inside Access Point: A narrow hole, about 1 foot by 5 feet, is made near your basement wall.
• Outside Access Point: A small 3-by-3-foot hole is dug close to the property line.
The torpedo is launched from the basement access point, burrowing a new underground path beneath your home’s foundation and extending to the hole near the property line. Depending on soil conditions, this method can handle distances of 30 feet or more. Once the new tunnel is ready, the plumber installs a high-quality, durable pipe and connects it to both the municipal water main and your home’s plumbing. The old water line is disconnected and left safely buried.
Key Things to Know About Trenchless Water Line Upgrades
• Ideal Soil Conditions: The torpedo method is most effective when following the existing water line path, especially in areas where the soil is not heavily compacted. It travels in a straight line, making only slight depth and directional adjustments as needed.
• Proper Pipe Depth: To prevent freezing, the new water line must be buried at least four feet deep. This depth requirement ensures the pipe remains secure even during harsh Toronto winters.
• Distance Limitations: For distances up to 30 feet, one torpedo run is typically sufficient. However, if your property requires a longer tunnel, an additional access point may be necessary to divide the pathway into manageable sections.
Toronto properties are often well-suited for the trenchless method, as the distance from the house to the municipal connection point rarely exceeds 30 feet.
