We responded to an emergency service call in the **Sunset District of San Francisco, CA**, regarding a major water leak underneath the kitchen sink that was flooding the kitchen tiles. Upon inspection, we discovered the source was a failing, sub-standard flexible corrugated plastic drain pipe that was trapping debris and split at the seams.
We removed the failing drain assembly and replaced it with a code-compliant, durable rigid white plastic P-trap assembly and a new PVC tailpiece connected directly from the sink. Unlike flexible connections, this smooth-walled setup prevents waste build-up and leaks. We then conducted thorough pressure and flow testing, running both hot and cold lines to ensure the entire system was completely watertight and leak-free.
