The Problem

Hydro-vac excavation beneath the home's foundation on Washington Street in Hollywood exposed severely damaged kitchen and laundry branch drains. Completely rotted cast-iron sanitary piping with holes and missing sections was found in the 3-foot by 3-foot service tunnel area.

Diagnostic Process

Hydro-vac excavation was underway beneath the home's foundation, with the truck, tank, hoses, PVC suction piping, and safety cones set up on site. Crew members removed numerous coral boulders and coral rock from the 3-foot by 3-foot service tunnel using hydro-vac and manual chipping hammer work.

Once access was established, the exposed kitchen and laundry branch drains were inspected and found to be severely damaged — completely rotted cast-iron sanitary piping with holes or missing sections. Full cast iron replacement was recommended.

Step-by-Step Remediation

  1. 1

    Assessment & Permit Applications

    We begin with a detailed assessment of the existing cast iron plumbing system to identify damaged, deteriorated, or failing pipe sections. Our team reviews the project scope, access points, property conditions, and code requirements before submitting the necessary permit applications to ensure the replacement work is completed properly and in compliance with local regulations.

  2. 2

    Tunneling, Pipe Removal & PVC Replacement

    Once permits are approved, we carefully tunnel beneath the home to access the existing cast iron drain lines while minimizing disruption to the property. The old cast iron pipes are removed and replaced with durable PVC piping. After the new plumbing system is installed, we schedule and complete the required plumbing rough inspection to confirm the work meets code before moving forward.

  3. 3

    Final Plumbing Inspection & Tunnel Backfill

    After the rough inspection is approved, we proceed with the final plumbing inspection to verify that the replacement system is properly installed and ready for long-term use. Once final approval is received, the tunnel is carefully backfilled and compacted, restoring the underground access areas as safely and securely as possible.

  4. 4

    Job Site Cleanup & Final Walkthrough

    To complete the project, we clean all work areas, access points, and egress areas used during the job. Our team removes debris, organizes the site, and makes every effort to leave the customer's home and property cleaner than we found it. A final walkthrough ensures the work area is restored and the customer is satisfied with the completed project.

Issues Encountered & How We Solved It

On this Hollywood Washington Street job we encountered a substantial amount of coral boulders and coral rock in the 3-foot by 3-foot service tunnel beneath the foundation. They were removed by hydro-vac excavation and by hand with a chipping hammer in order to expose the cast-iron sanitary drain lines so the damaged piping could be assessed and replaced. At the end of each workday the tunnel was secured with plywood, caution tape, and the gate closed.

"Very happy with their work, starting with the camera pipe inspection and then the replacement of the corroded cast iron pipes. Steve (owner) was very responsive to my questions and explained everything that needed to be done. Casey and Anthony did excellent work getting the pipes out and replacing them all. Thank you Draining King Plumbing, you did a great job in Hollywood. "

"Drain King Plumbing is hands down one of the best companies I’ve ever worked with. A friend recommended the owner, Steven, after I was told I needed to replace the cast-iron pipes in my Dania Beach home—and I’m extremely glad I listened. From the very first text, Steven was responsive, honest, and professional. Even though I already had a sewer camera inspection from another company, he insisted on doing his own instead of quoting off someone else’s work, which really showed integrity. Casey handled the inspections and documentation, Brandon and Casey installed the new piping flawlessly, and Anthony did an excellent job with the excavation—even with high tide and tough ground conditions. Stephanie made the permitting process smooth and stress-free. The workmanship and materials were top-notch, communication was clear throughout, and everything was documented with before-and-after photos and videos. They even restored my landscaping when the job was finished. Best of all, they provided a lifetime warranty on both the work and the materials, which says everything about the pride they take in their work. If you need plumbing work—especially cast-iron pipe replacement—do yourself a favor and call Drain King Plumbing. These guys truly live up to their name. "

"Drain King Plumbing is truly the real deal and absolutely deserves every one of their five-star reviews. We had a serious sewer emergency very early in the morning at our home when sewage backed up through our shower and toilet. I searched on Google for an emergency sewer and drain plumber near me, and Drain King Plumbing came up first. Anthony arrived quickly, cleared the line to stop the backup, and performed a camera inspection that showed our underground cast-iron pipes were broken and failing. He explained everything clearly and honestly. One of our biggest concerns came from friends and family who had similar issues — they told us their floors were cut open and that they had to move out for months. We also had other companies talk about lining the pipe as a temporary fix. Drain King Plumbing took a completely different approach. Instead of cutting floors or using a liner as a band-aid, they tunneled underneath the home and fully replaced the broken cast-iron pipes. They worked around our schedule and completed the pipe replacement while we were at work. We never had to move out, never had to stop using our plumbing, and it honestly felt like just another normal day. From there, the entire team moved fast and worked efficiently. Anthony handled the excavation crew, while Casey and Carlos completed the plumbing work and replaced the old cast-iron pipes with new PVC. Steven, the owner, was on top of everything from start to finish and made sure nothing was delayed. He immediately had Stephanie, the office manager, help us with the permit process, and the permit was approved the same day. The pricing was fair and reasonable, communication was excellent, and all inspections passed. This team works together incredibly well and delivers exactly what they promise. If you’re dealing with an emergency sewer issue or cast-iron pipe replacement, Drain King Plumbing is a true five-star company and I would recommend them without hesitation. "
