Signs of a water leak in your home
Start with an initial assessment to look for obvious signs and visible signs of water leakage inside a wall. Before you can detect how to find a water leak in your walls, you need to know if you are actually experiencing a water leak in your walls. If you suspect something isn’t right it is always better to be safe than sorry and go and check out the issue at hand.
If you notice some of the following issues you are experiencing a water leak in your property:
Mould or Mildew Growth: Excess moisture from a leak can foster the growth of mould or mildew, visible as dark spots or patches on the wall surface.
Soft or Sagging Walls: If the drywall or wall material becomes saturated with water, it might feel soft or appear swollen and saggy.
Unexplained Increase in Water Bills: A sudden increase in water usage or bills without any change in your routine could indicate a hidden leak.
Sounds of Dripping or Running Water: You might hear faint dripping or rushing water behind the walls, especially if the leak is significant.
Decreased Water Pressure: A leak in a pipe within the walls could cause a decrease in water pressure in your taps or shower.
Visible Efflorescence: This is a whitish, chalky residue that appears on walls when water evaporates, leaving mineral deposits behind. It can indicate water movement through the wall.
Peeling paint or wallpaper: Moisture from a leak can cause paint or wallpaper to bubble, blister, or peel, which are signs of water damage.
Musty odor, musty smell, or musty smells: Persistent musty odors can indicate hidden moisture or mould growth in the affected area behind the wall.
Wet spots or wet walls: The presence of wet spots or wet walls is a visible sign of water seeping or water leakage from a leaky pipe.
Mould growth: Mould growth is a common indicator of hidden leaks and ongoing moisture issues.
Other signs, such as subtle changes in wall texture or color, may also indicate hidden leaks. Using a moisture meter to check moisture levels and moisture content in the wall can help pinpoint the affected area and confirm the presence of water leakage.
Five ways how to detect water leaks in your walls
Now that you have investigated and are clear that you have a water leak in your walls, you need to identify the source and problem. This may seem simple on paper; however, if you are inexperienced or can’t physically see the source of the leak, it can actually be very difficult to identify. Detecting hidden leaks inside a wall is challenging, and it’s crucial to find the exact location of the leak source to prevent further damage.
Fortunately, by using one of these five ways to detect a water leak inside a wall, you will be able to locate the leak source and stop it from becoming a serious issue by putting a temporary stop in place until a professional plumber can come and amend the issue.
The five ways on how to detect water leaks in your wall include:
Water meter reading
Water pressure test
Check your utility bills
Listen for running water
Contact a local plumber
1. Water meter reading
To detect hidden leaks, perform a water meter test. Start by ensuring all water sources in your home are turned off, including taps, appliances, and irrigation systems.
Locate your water meter and take note of the current reading. For accuracy, take multiple readings at different times, making sure no water is being used between checks. After a few hours, check the water meter again. Even a slight increase in the water meter reading, despite no water usage, can indicate a hidden leak.
This water meter test helps isolate the possibility of a leak within your property and allows you to investigate your walls to find the source.
2. Water pressure test
Another way you can identify if you have a leak inside your wall in your property is by running a water pressure test. Before starting, make sure to turn off the main water supply to prevent further water damage and ensure accurate results. Then, turn off all water sources within your home. Locate the main water shut-off valve and attach a pressure gauge to an outdoor tap. Do this whilst all the other taps and water-using appliances are turned off.
Next, turn on the outdoor tap and let the water flow through the pressure gauge. Make a note of the pressure reading displayed on the gauge. After this, leave the water turned off for a few hours and then return to check the gauge.
If the pressure has dropped significantly, it could indicate a leak within the walls or the plumbing system. A drop in pressure suggests that water is escaping somewhere, which could be due to faulty plumbing, prompting further investigation to locate and repair the potential leak inside your wall.
3. Check your utility bills
Reviewing your water bill can be a useful way to spot potential hidden leaks within your walls. Compare your recent water bills with past usage patterns. If you notice a sudden and unexplained increase in water consumption or a spike in your water bill without a change in your routine or seasonal factors such as running more baths in the winter and using more water-based appliances in the winter; it could indicate a hidden leak.
Analyse the usage patterns over several billing cycles to determine if there’s a consistent and unexplained rise in water consumption. Make sure to check that your provider hasn’t increased the price of their services as well!
If you have done all this and still notice a substantial and persistent increase in water usage, despite no change in your habits, this could signal a leak that might be concealed within your walls.
4. Listen for running water
Once you have identified that there is a leak somewhere in your home, using one of the three methods above, it is now time to try and work out where it is coming from. You can do this by listening out for the sound of running water.
Firstly, start by turning off all water sources and appliances in your home that use water. Find a quiet location close to the walls that you must suspect of a leak and concentrate on listening for any faint sounds of running water. Pay special attention to subtle noises, such as faint dripping or water movement, as these can help you identify hidden leaks before any visible signs appear. If you have a stethoscope use this or simply just place your ear against the wall surface.
The leak might produce a subtle but distinct sound, such as a hissing, dripping, or rushing water noise. Move along the wall, focusing on different areas to pinpoint the sound’s location. If you hear persistent water movement despite all sources being off, it can indicate a hidden leak within the wall.
5. Contact a WIAPS-approved Plumbing Company
Once you have identified the source of the leak in your wall, you can now finally work on putting a stop to it and getting it repaired. If you are still struggling to find the leak or can’t identify the actual source even though you can hear it and all evidence points to a water leak, your best option is to get in contact with a trusted and WIAPS-approved local plumbing company that will help identify the actual source and fix your leak as quickly as possible.
Always remember that the more time you give to a water leak without fixing the issue, the more damage and expenses you will have to pay out to repair the structure of your home and your damaged belongings. We recommend calling a local plumber as soon as you notice a leak is present within your walls.
