Why is my bathroom sink leaking?

You walk into the bathroom and you find a puddle of water in front of the sink. You proceed to mop it up and go about your business. Several hours later, you return to the loo only to find an even bigger puddle in the exact spot. And that’s when it dawned on you—your bathroom sink is leaking.

Leaking is a common yet a pretty exasperating thing that can happen to bathroom fixtures, which often occurs in sinks. If not taken care of immediately, these leaks can leave your walls, flooring materials and vanities with mould, fungi and structural damage.

To resolve this, you must pinpoint the exact source of leakage and identify its cause. Diagnosing the problem accordingly will allow you to come up with the best action plan. It will also enable you to make better and more careful decisions when using the sink.

Let’s discuss the areas where the bathroom sink usually leaks.

Water supply lines

You can tell that the leaking stems from your water supply lines if it’s incessant or fairly constant.

Leakage in this supply line is also more likely to show spurting water around the area. The reason for this is that pressure from the line is forceful considering it’s where water from the fixture comes from.

The strong pressure in this area allows water that’s escaped the line to shoot further. Otherwise, the leakage takes form as tiny drops of water that move rapidly.

Oftentimes, leaking water supply lines require replacement. Other times, this issue only demands a tightened-up connection.

Drain

You know the leak originates at the drain if it’s accompanied by weird smell. In many cases, it simply takes form as complete wetness when you open the sink cabinet.

Like water supply lines, leaking drains could be the outcome of loose nuts. Or it could be the result of cracks present in the piping system.

Drain leakage, alongside clogging, is a common general plumbing problem that plumbers from Revesby and other areas in Sydney usually deal with.

Faucet

Leakage in the faucet isn’t as common as the first two items on the list but it does happen as well. The best way to resolve such an issue is to have it replaced.
