WHY WATER LEAKS FROM THE BOTTOM OF MY WASHBASIN

 Water leaks from the bottom of the bathroom sink can be annoying and dangerous. Recognising and resolving these leaks early prevents water damage and helps save water. 

If the bathroom sink leaks below the water level, this can be due to several factors. The most common causes are a worn gasket, corrosion of the pipe or problems with the sink drain, such as a clogged drain that increases pressure within the plumbing system. Components such as the sink flange, trap P and supply lines should be inspected for faults or incorrect installation.

The integrity of the entire bathroom sink system depends to a large extent on the proper functioning of each component, from the tap to the drain. Leaks can occur if components are not tightened properly or if parts such as O-rings, washers or fixing nuts that have deteriorated over time need to be replaced.

By knowing your bathroom plumbing and the mechanics of the sink, you will be better equipped to keep it in good condition and prevent future leaks.

OVERVIEW OF BATHROOM SINK COMPONENTS

Knowing the various components of the bathroom sink is essential for effectively diagnosing leaks. These key elements, which form the heart of the bathroom plumbing system, work together to ensure efficient drainage and minimal leaks. Here is an overview of the main components involved in the functioning of the sink:

Faucet or tap: this is the tap through which water flows. Problems such as a loose connection or worn washers can cause leaks at the base.

Sink drain: This is where the water flows out of the sink. A clogged drain can cause water to overflow, stressing other components and potentially causing leaks.

Siphon: This curved pipe under the sink prevents exhaust gases from entering the house and traps debris discharged from the sink. If the siphon does not retain water properly due to cracks or loose connections, a leak can occur.

Supply lines: These pipes carry water from the main plumbing system of the house to the tap. Leaks often occur if connections are not tightened properly or if pipes need to be replaced due to wear and tear.

Gaskets and washers: Placed in various fittings, they provide a tight seal to prevent water from escaping. Over time, they can deteriorate and must be replaced to maintain a tight seal.

Drain flange: This component connects the sink to the drain. If it is not sealed with plumber's putty, water can leak from this connection.
