How to find a leaking water pipe under concrete?

To find a leaking water pipe under concrete you should do the below things:

  • Be on the lookout for a significant increase in your water bill. In most situations, your water or sewer bill is the first sign that your underground pipes are leaking. 
  • You may have a leaking pipe if you see a huge price jump from one month to the next, or if your water use remains the same each month.
  • If your water meter is spinning despite the fact that you are not using any water in your home, there is either a leak someplace or your toilet is running.
  • Find any appliances that have leaks. Check for leaks in toilets and other plumbing fixtures first to determine the source of any increases in your water use. You may check for leaks by putting food coloring in the tank and waiting 10 minutes before flushing. 
  • You have a toilet leak if the color has spread to the bowl. Look for puddles or drips of water surrounding the appliance or its related pipes if it is a faucet or other water-based device.
  • Look for water puddles, soggy carpet, or twisted timber in your home. Slab leaks cause water to accumulate beneath the concrete foundation of your home. This water may pool on top of your flooring, yard, or even the concrete itself in order to get out of your house. 
  • Find spots that seem darker or wetter on carpeted floors to see if there are any leaks. Be on the lookout for signs of warping in your wood paneled flooring.
  • A stagnant body of water is an ideal breeding ground for mold and mildew. Be conscious of places in your home that have a musty or nasty smell over a lengthy period of time, even if you can’t see it. 
  • There are two places where mold and mildew are most likely to grow: beneath carpet and behind drywall.

Is a water meter useful to find a leaking water pipe under concrete?

Yes, a water meter is useful to find a leaking water pipe under concrete. Your water meter will notify you immediately whether or not there is a problem. 

A leak indication (typically shown as a little triangle or sailing wheel), a sweep hand (described as a clock-like hand that covers the meter), or an odometer (a row of numbers) are all examples of leak detection devices that certain meters may have. 

The valve itself may also be checked for any modifications. On the streetside or kerbside, the water meter will have a covered lid and be accessible from the ground level.

Remove the lid and clean away any debris or dirt so that you can clearly see the water meter and valve. Note where the needle is positioned and perhaps make a little notation to be extra sure. Shut off the water to your house for at least 30 minutes once this step has been completed. 

Head back to the water meter and take a look at its location; if it has moved even with the water turned off and no one in your home using it – this is a reasonably strong sign of an exterior water leak anywhere in your external supply between the water meter and your internal stopcock.

Leak detectors may not stop spinning, or the odometer’s numbers may continue to rise even after the water is shut off, depending on the system you have. It’s possible that the sweep hand will move a lot during the course of many minutes.

Can water leak through concrete?

Yes. Porous concrete is what makes it possible for water to leak through the concrete.

When it’s originally placed, concrete is poured in a moist state. That moisture needs to go someplace as it dries. Capillaries in concrete are formed when water evaporates. When the concrete sets, the capillary system is still there.

It is via these microscopic channels that water seeps into the concrete when it comes into touch with the surface, such as in the case of a leak. Concrete is very durable on a macro level. Microscopically, it resembles more of a sponge.

In addition, concrete includes calcium, which dissolves when it comes into contact with water. As additional calcium is dissolved by the water, the little aqueducts will grow in size.

How to detect a water leak under a concrete slab?

  • Having a slab leak causes water to build up under the concrete foundation of your house. When there are no more places for the water to go, it will begin to rise to the surface. Water may eventually reach the top of your house. 
  • At that point, the water will begin dripping into your yard or into the lower floors of your house. It’s imperative that you solve the situation as soon as possible if it becomes this severe. 
  • Sinkholes, warped flooring, and even the structural integrity of the whole house may be caused by standing water.
  • Even in the early phases of a slab leak, it is difficult to discover. Mold is the most common cause of these issues. 
  • Mold starts to grow in the cracks and crevices of your house as soon as water leaks. It will begin to smell as soon as the mold begins to develop. The musty odor might be the first sign that anything is amiss.
  • Look for warm places when walking around barefoot on the floor. Make a note of the location where you experience a tingling sensation and return to it a day later. If the same location is still warm, you may have a leak in your hot water line.
  • If you have a sewage leak, you’ll probably be able to detect the stench of sewage in your home. Lower-level flooring may be damaged by sewage leaks, which can cause cracking or warping. Sewage leaks may be detected by looking for cracks in your tile, brick, or molding.

Conclusion

When it comes to finding water leaks beneath concrete, the severity of the leak and the location of the leak might make it simple or difficult. One of the best methods to fix a problem like a water leak beneath concrete is to hire a reputable plumber.

Water leak detection services need immediate attention. Maintain the health of your plumbing system. In order to save both time and money, you should try to locate any leaks as soon as you can.
