Tunnel Entry
We access your home’s cast iron pipes by digging a hole from the outside to gain access to the plumbing system.
We access your home’s cast iron pipes by digging a hole from the outside to gain access to the plumbing system.
After backfilling, we fill the tunnel void using limestone to ensure a solid base.
Over time, cast iron pipes can corrode, weaken, and ultimately fail. While cast iron pipes' life expectancy is about 50-70 years under normal conditions, factors like soil and environmental conditions can decrease their life span.
The safest, permanent solution is a complete replacement of the sewer system. Bob Smith Plumbing is the leading expert in replacing these aging pipes, ensuring your underground plumbing runs smoother and lasts longer. Many things set our work apart, one important item is the stainless-steel package for the hanger system we use to prevent galvanic action (the corrosive effect resulting from dissimilar metals in direct contact with each other).
Cross sections consist of diverging points in the system where pipes go in two different directions. Double Y are adjacent cross sections next to each other, which can create stoppages and issues for cleaning the system.
We eliminated Double Y cross sections to prevent sewer machinery from crossing over when cleaning the system in the future.
Laundry lines in cast iron pipe systems are typically two inches in diameter.
We upgrade the laundry line to three-inch PVC to ensure your washer can effortlessly expel soap, grime, and dirt.
Cast iron pipe sink drains have a 90-degree turn. Not replacing it creates a future weak point in the system.
We replace 90 degree turns with new PVC to ensure we update the entire system—even in the hardest to reach places (like the kitchen).
Water lines in cast iron pipe systems may run adjacent to the sewer pipes, leaving the water lines exposed.
We sleeve all water lines to protect them against rock abrasion and other circumstances that may cause failure.
We use an advanced hydro-excavation method to tunnel beneath your residence. Our state-of-the-art equipment merges high-pressure water with vacuum suction, facilitating swift and precise soil removal. We are proud to utilize proprietary hydro-excavation machinery that's both efficient and environmentally responsible.
The final phase of our pipe replacement process is backfilling. Proper backfilling restores excavated areas to their original, or often superior, condition. Unlike many of our competitors, we choose premium crushed limestone for its capacity to yield optimal compaction, ensuring the strongest, most resilient, and safest base.
Bob Smith Plumbing uses a 100% stainless-steel pipe support system (no mixed metals) to prevent rust.
