Supply Lines. If you have water squirting everywhere, this is probably the kind of water leak you have happening. Though you can sometimes get a slow seeping in the supply lines, the pressure in the lines usually makes it travel farther once it has escaped the lines.

However, mold or mildew on non-shower walls or in corners of the bathroom are a clear sign that water is leaking somewhere and finding its way to those areas. 3. Damaged Paint or Wallpaper

Bathroom sink leakages occur because of poor installation of the fixtures that allow water to pass through. There will often be a need to use the plumber’s putty when installing certain features, such as the drain outlet flange.

Look for dripping water, signs of corrosion, rust and other problems that could be the cause of a leak. If you see no obvious source of the leak, run the water in your sink and then look under the sink and watch for moisture to gather.

Bathroom sink leaks are usually caused by a bad drain pipe, a loose pipe connection or a leaky sink drain flange. Fill your sink with water to figure out exactly where your leak is coming from; then repair or replace the defective part.

Arguably the most common reason you’ll find water beneath your sink is that your drain has a leak in it. Shifting plumbing lines, worn-out connections, or even pipe corrosion could cause fractures in the plumbing lines beneath your sink, which cause water that flows down your drain to slowly and steadily leak out.

The most common sources of a leaking faucet – a worn out washer or gasket, a loose O ring, corrosion in the valve seat – can be detected and fixed easily with most faucet repair kits. Damaged or deteriorated faucet parts are the leading cause of leaks in bathroom, shower and kitchen faucets, especially if you have an older one in your home.

Why is there a wet spot on the ceiling below the bathroom? When water’s leaking within the wall, or from the bathtub drain above, you’ll find water seeping out below the source of the leak. Sometimes, water won’t actually leak out — you’ll find the drywall sagging and paint bubbling in the affected area. If you see the ceiling sagging below the bathroom, you can prevent the collapse of the ceiling and further damage by poking a small hole in the ceiling drywall.

Identify The Leak . Water leaks are often because of pinholes in your plumbing system or small failures in caulking or other exterior materials. Water takes the easiest path down to the ground, so it will often travel along the framing in the walls.
