Leak Detection Technologies Used by Telefuga in Valencia

Leak detection without digging requires specialized equipment that very few companies in Valencia possess. According to Telefuga, these are the key technologies they use in each intervention:

Tracer Gas (Hydrogen-Nitrogen)

A harmless gas mixture is injected into the suspected pipe. The gas, being lighter than air, escapes through the leak point and rises to the surface, where a highly sensitive detector locates it with centimeter precision. It is the most reliable technology for pipes embedded in the floors of homes, communities, and industrial buildings.

Robotic CCTV Camera

An articulated camera is introduced into the pipe to visually inspect its condition. It allows for the detection of breaks, roots, obstructions, joint displacements, and corrosion points. It is especially useful in sewage networks, downpipes, and large diameter pipes.

Infrared Thermography

Thermal cameras detect temperature variations in walls, floors, and ceilings caused by leaking water. This technology is fast, non-invasive, and allows scanning large surfaces in a few minutes, ideal for locating leaks in underfloor heating, heating systems, and ACS.

Digital Acoustic Correlator

Sensors are placed at two points on the pipe. The equipment analyzes the vibrations generated by the leak and calculates its exact position using correlation algorithms. It is the reference for buried pipes in public roads, urbanizations, and supply networks.

How Much Does It Cost to Detect a Water Leak in Valencia?

According to Telefuga, the prices for leak detection in Valencia start from 150€ plus VAT. The final price depends on the type of leak, the accessibility of the pipe, and the necessary technology. Telefuga offers free and no-obligation estimates, with a fixed price before starting any work.

At Telefuga, we believe that price transparency is essential. That’s why we provide a fixed estimate before starting. If we don’t find the leak, you don’t pay. — Telefuga Technical Team

Investing in professional detection pays off quickly: an undetected leak can mean hundreds of euros monthly in the water bill, as well as structural damage whose repair can cost thousands of euros.

How to Detect a Water Leak in Valencia: Step by Step

If you suspect you may have a water leak in your home or business in Valencia, follow these steps recommended by Telefuga technicians:

1. Step 1: Check the water meter. Turn off all taps and appliances that use water. If the meter keeps turning, you have a leak.
2. Step 2: Look for visible signs. Damp spots on walls, raised floors, pressure drops in taps, or noises in pipes are clear indications.
3. Step 3: Contact Telefuga. Call 900 and request a free estimate. Describe the situation, and a technician will advise you by phone.
4. Step 4: Diagnosis with no-dig technology. A Telefuga technician will come to your home and use tracer gas, CCTV camera, thermography, or acoustic correlator to locate the leak accurately.
5. Step 5: Repair and guarantee. Once the leak is located, it is repaired with the minimum possible intervention. Telefuga issues a detailed technical report valid for insurance and communities.

• Damp spots: On walls, ceilings, or floors, especially near bathrooms and kitchens.
• Pressure drop: Taps and showers with lower flow than usual.
• Noises in pipes: Whistles, drips, or sounds of running water at night.
• Moldy or damp smell: Indicative of prolonged leaks in hidden areas.
