Slab leaks can be tricky to identify, especially when there are no visible signs of damage. At C & R Plumbing, we recently encountered such a case in Huntington Beach, CA, where a homeowner detected a slab leak based solely on the sound of running water in their bathroom. Despite the absence of moisture or water pressure drops, the issue required prompt action. Here’s how we handled the situation, which ultimately involved a PEX reroute for both the shower and sink.
The Problem: Mysterious Running Water Sound
The homeowner first became concerned when they noticed the sound of running water in the bathroom, even when all fixtures were turned off. There were no visible signs of moisture, no damp spots on the floor, and no unusual drops in water pressure—common indicators of a plumbing issue were entirely absent. However, the persistent sound suggested a hidden problem, so they reached out to us for a professional assessment.
The Solution: PEX Reroute to Address the Hidden Slab Leak
Given the subtlety of the issue, our first step was to determine whether there was a hidden leak beneath the slab. Here’s how we approached the job:
- Leak Detection: Using advanced electronic leak detection technology, we carefully listened and traced the sound to pinpoint the exact location of the leak beneath the home’s concrete foundation. This non-invasive method allowed us to identify the problem without unnecessary disruption to the home.
- Assessment and Planning: After confirming the slab leak, we discussed the best solution with the homeowner. Despite the lack of visible damage, the leak had compromised the pipes under the slab, and we recommended a PEX reroute to avoid future complications.
- PEX Reroute Installation: We chose PEX piping for the reroute due to its durability and resistance to corrosion. The new pipes were installed through the walls and attic, bypassing the damaged section under the slab. This method not only avoided the need to break through the concrete but also ensured a long-lasting fix.
- Testing and Final Inspection: Once the reroute was complete, we thoroughly tested the new setup to ensure that everything was functioning correctly. The homeowner was relieved to find that the sound of running water had ceased, and the plumbing system was back in perfect working order.
The Benefits of PEX Reroute for Hidden Slab Leaks
In areas like Huntington Beach, where slab leaks can be difficult to detect, a PEX reroute offers several advantages:
- Non-Invasive Repair: By rerouting pipes above the slab, we avoid the need for costly and disruptive excavation.
- Long-Term Durability: PEX piping is highly resistant to the corrosion and wear that can lead to future leaks, especially in coastal environments.
- Prevents Future Issues: Even without visible signs of damage, addressing the issue proactively with a reroute helps prevent potential structural damage and water loss.
Importance of Prompt Attention to Subtle Signs
This case in Huntington Beach highlights the importance of paying attention to even the most subtle signs of a plumbing issue. While there were no obvious indicators of a slab leak, the homeowner’s attentiveness to the unusual sound in their bathroom prevented what could have become a much larger problem. Regular plumbing inspections and swift action when something seems off are crucial for maintaining the integrity of your home’s plumbing system.
