Normally, the first indicator of an underground leak is an abnormally high water bill. This may be due to an underground leak. Melex leak detection will assess the issue with the newest technology, and quickly diagnose the underground leak.

Initially, the indicator of an underground leak in the well line is the pump cycling more often and/or the loss of pressure. Melex water leak detection will locate the leak and make a prompt assessment.

If you suspect a leak and/or a hot spot on the floor, there may be a leak under the slab. Call Melex leak detection so we can locate the problem.

Due to heavy rain or snow, water may seep through cracks behind the drywall. Melex leak detection in Spokane will inspect the entry points and promptly locate the source of the leak.

Call Melex Detection before you dig. Melex will use the newest technology available to locate sewer laterals, storm drains, water lines, irrigation lines and power lines all in one appointment.

We will perform a complete pressure test of all underground plumbing to confirm that the leak is in the underground plumbing. Each line will be tested individually. If any line does not hold pressure during the pressure test, this is an indication of a cracked fitting or broken pipe.

Movement in the foundation of your home could be caused by a plumbing leak under the slab. Water and sewer lines beneath your home or commercial facility can cause cracks and movement in the structure. At Melex underground leak detection, we can find the leak to stop further erosion of the ground below your home or business. We can check for leak location with state-of-the-art equipment without using invasive procedures. When the leak is found, a contractor may be able to make repairs by exposing the broken pipe by tunneling under the slab or temporarily removing a small section of concrete from above.



    We have used Melex Detection in the past and have had great results. The determination and work ethic are very refreshing.

    We called a couple of other services before we found Melex. They did not find our leak and basically gave up after a few hours of searching.

    Sean stayed on the problem and even brought in some extra equipment to help with the search. We located our leak, and are very grateful that Melex detection was there. Prices are very reasonable, and the equipment is state of the art.

    You will be my first call next time!

    I want to thank Sean Moore for his quick response in locating a leak in our water system affecting about 20 patrons. We were leaking about 50k gallons per day. The water did not surface at all. Within 2 hours, Sean pinpointed the leak, and we had it repaired the same afternoon. I highly recommend Melex Detection.

    Thank you Sean.
