What San Jose Clients Say About Our Leak Detection Services
Had the plumber Daniel come to my condo today for a clogged toilet. He spent almost two hours snaking with a camera my drain and pulled out a huge clog of tree roots. He knew exactly what he was doing and did a wonderful job. I would recommend this company very much.
Ron K.
Great, reliable, and timely service at a reasonable price. I shopped around quite a bit before landing on CPI. Their rates were competitive, they responded promptly, and their plumber fixed a few issues quickly and without much fuss. I’ll definitely be calling them again the next time we have issues!
Allan Huynh
CPI Service was sent to my home by my condominium association. They agreed to a very early morning appointment and the gentleman arrived exactly on time. He went through the problem very methodically to see where the problem was. Something that no one else could figure out was taken care of in half an hour. I would very definitely recommend them.

San Jose Leak Detection FAQs
What Is Leak Detection?
Leak detection is the process of locating hidden or visible water leaks in plumbing systems using specialized tools like acoustic sensors, thermal imaging, and pressure testing equipment. In San Jose homes, this often involves non-invasive methods to pinpoint the source of a leak without damaging walls, floors, or landscaping. CPI Services uses advanced technology to ensure fast, accurate identification and repair, minimizing both water waste and property damage.
How Do I Know If I Have A Leak?
Warning signs of a leak include spikes in your water bill, wet spots on walls or floors, mold or mildew smells, and dripping sounds when no water is running. Other clues may be low water pressure or unusually green patches in the yard, indicating underground line issues. If you notice any of these symptoms, a quick inspection by CPI Services can help confirm and resolve the issue before it worsens.
Are Leak Detection Services Available After Hours?
Yes. At CPI Services, we provide emergency leak detection services 24/7 across San Jose, including weekends and holidays. Plumbing emergencies don’t follow business hours, and delays can lead to costly structural damage. Our technicians are always ready to respond quickly, equipped with the right tools to diagnose and mitigate the problem on the spot.
What Are The Most Common Issues You Handle?
We frequently address leaks related to slabs, water pipes, faucets, toilets, underground lines, and sewer systems. These issues are often caused by pipe corrosion, shifting foundations, aging fixtures, or root intrusions. CPI Services is equipped to handle both minor and major leak scenarios using proven techniques and state-certified expertise, ensuring long-term resolution and system integrity.
