Challenging Drain System Repair with Limited Access
During a routine building inspection, I encountered a drain system with severely limited access and space for repairs. The drainage pipes were concealed within a concrete slab, making it impossible to access them directly.
To overcome this limitation, I devised an innovative solution:
- Inspection Camera: I used a specialized camera to inspect the pipes remotely. This allowed me to identify the location and severity of the blockage.
- Hydro Jetting through Existing Fixtures: Instead of excavating the concrete, I utilized existing fixtures, such as floor drains and sinks, to access the drain system. I connected a hydro jetting hose to these fixtures and used high-pressure water to scour the pipes and remove the blockage.
