Keep reading to learn more about the common causes of bathroom leaks. Let’s dive in!
Poor Installation of Drainage Pipes
Poorly installed drainage pipes can lead to the accumulation of wastewater and subsequent overflow. This water buildup can cause leakage around the sink due to water pressure.
Additionally, improper installation without proper seals can lead to leaking as well. These can occur over time due to incorrect fitting of the pipes with the sink and the wall.
Lastly, deterioration of the pipes in time due to aging can also cause the water to leak at the connections. All of these issues can be avoided with proper installation and regular maintenance.
Damaged or Corroded Valves
Most sink valves are made of metal and will eventually succumb to corrosion over time. This causes the internal metal pieces to currently and become unable to contain the water.
This type of corrosion often has tell-tale signs of discoloration or even bubbles around the valves. It’s important to inspect them periodically and replace them when any issues are found.
Also, be sure to shut off the water supply to the bathroom before making any repairs. This can help prevent flooding in the bathroom as valves are changed out.
However, the cost of replacing old valves may have an upfront cost. But it may save more money in the long run by preventing major water damage.
Loose Connections
Loose pipes can wiggle and create tiny air pockets in the connections that can lead to water leakage. Over time, the water pressure can slowly push out these air pockets, and water will seep out of the connection.
Many times pipes and fittings can become loose or over-tightened because of vibration and general wear and tear. Therefore, it’s crucial to inspect all connections by tightening them up and checking for cracked areas.
Clogged Drain Pipe
If the drain pipe becomes clogged, it is unable to efficiently drain water and could cause a leak. Clogged drain pipes are usually caused by the following:
- Soap scum buildup
- Hair
- Toothpaste
- Grease
- Other debris
These are the normal things that usually form a blockage that prevents normal water flow. When the water cannot flow freely through the pipe, pressure begins, and this will cause the water to leak out from the seals in the pipes.
To determine the exact reason for a leak, it is best to call a professional plumber for bathroom leak repair to properly inspect the entire plumbing system.
The Most Common Causes of Leak Under Bathroom Sink
A water leak under bathroom sinks can be caused by various factors, such as loose supply lines, clogged drains, or a damaged drain. To fix these issues, start by tightening the connections, unclogging the drain, and ensuring that it is properly sealed.
If these solutions don’t fix the issue, call a professional for help.
