Pipe Leak and Slab Leak Detection

Ray May Plumbing can perform leak detection services under slabs, gas lines, underground water leaks, and line tracing. We offer 24 hour plumbing and emergency leak detection services.

Our company has over three decades of leak detection experience and we can detect any leak with our state of the art leak detection equipment.

We offer state of the art leak detection services to ensure your leak is pinpointed in the exact location so you do not have to tear up your whole slab or dig in unnecessary areas.

Precise location of your leak is truly the most important objective when performing leak detection services under slabs, and underground. It saves time and money.


Electronic and Radio Leak Detection

We have all of the necessary equipment to conduct leak detection using electronic and radio methods.

  • We are able to send a radio transmitter line down the pipe and detect the leak with a radio frequency from the surface.
  • We have electronic equipment we can hook onto a line that send a signal through the line to detect the exact location of the leak.

The great thing about our electronic and radio leak detection services is our ability to detect a leak on pipes from less than ½” all the way up to 12” diameter pipes and up to 1200 feet from the inlet.

How Do I Know If I Have A Slab Leak or a Gas Leak?

You may have a slab leak or a gas leak if you notice the following in your house, commercial or residential building:

  • a wet or soggy floor in your house,
  • an excessively high water bill
  • or a high gas bill.

If you hear water running constantly or smell an odor of gas (typically gas smells like pungent garlic), you may want to contact us and have us diagnose your plumbing system.

What Causes Slab Leaks?

There are many situations that can create a slab leak. The most common causes of a slab leak are:

  • You may have piping that was originally installed poorly.
  • The expansion of the earth and concrete due to increases and decreases in temperature.
  • Extremely contaminated or warm soil may lead to a burst pipe underground, or merely a pinhole.
  • The PH in the water in Southern California may be affecting your pipes.

Another cause of a slab leak, especially for those that live in the vicinity of Mt. Baldy there may be the heated water coming from the water heater to the faucet. Because a pipe is can expand when heated and contract when it cools, the hot water traveling through the pipe causes the pipe to expand and as the pipe cools down it will contract. During this process of expansion and contraction, the pipe can acquire a pinhole leak. This tends to warp floors, create damp carpet, create mildew and mold, and increase water and gas bills.

Ray May Plumbing Can Detect, Diagnose, and Repair Slab Leaks Efficiently

What Is Best Way To Determine A Slab or Gas Leak?

The best way to determine a leak with either gas or water is to:

If you suspect a leak, shut off all valves inside and outside the building except the main valve (the main valve is usually located near the edge of your property closest to the street).

After shutting off the proper valves (either water or gas depending on what you are checking for), look at the meter that corresponds to the main valve and see if the meter on the valve is still moving. If the meter is still moving it is extremely likely, you have a slab leak, underground leak, or a gas leak somewhere in the system.

"If The Meter For The Main Valve Is Still Moving After Shutting Off All Other Valves You Have A Leak."
