The Drip, Drip, Drip of Doom

You hear it at night, a faint dripping sound coming from your bathroom. At first, you brush it off as nothing, but as the days go by, the dripping intensifies.

You investigate and discover the culprit: a leaky basin faucet. A slow leak might seem harmless, but those drips can quickly add up, wasting water and driving up your bill.

Facing the prospect of a plumber’s visit or a hefty water bill, you start wondering if there’s another option. This is where DIY basin leak repair comes in.

Identifying the Leak Source

When it comes to fixing a leaky basin, the first and most critical step is accurately identifying the leak’s source. By pinpointing the exact location of the problem, you can save valuable time and money while also preventing further damage to your bathroom.

Targeting the right component for repair means you won’t waste resources replacing parts that don’t need fixing. It also ensures that you stop the water from seeping into other areas, which can lead to more extensive damage, such as mould growth or structural issues.

To help you locate the leak, here’s a guide to common basin leak locations and the clues that can help you pinpoint the culprit:

Fixing Basin Pipe Leak

Tap Base

If you notice a drip or puddle at the base of your faucet, the likely cause is a worn washer or O-ring. These small but essential components can deteriorate over time, allowing water to escape. Replacing the washer or O-ring is usually a straightforward fix.


Leaking handles can have a few different causes. If the leak is coming from the base of the handle, it might be due to a loose packing nut that needs tightening. If the leak persists after tightening, the internal components of the handle may need replacement.

Spray Hose Connection (if applicable)

If your basin features a spray hose, wetness or dripping near the hose connection can indicate a problem. Tightening the connection may be a simple matter, or the hose itself may have developed a leak and require repair or replacement.

Supply Line Connections

The supply lines are the pipes that bring fresh water to your faucet. If you notice dampness or dripping around these connections, it could be due to loose fittings or corrosion.

Tightening the connections with a wrench may solve the issue, but heavily corroded fittings may need to be replaced.

Drain Pipes

If you see water pooling under your basin or in the cabinet below, the problem likely lies with the drain pipes. A damaged or loose pipe can allow water to escape, leading to leaks and potential water damage. Depending on the extent of the issue, the pipes may need repair or replacement.

By methodically checking each potential leak source, you can zero in on the problem area and take appropriate action. Remember, if you’re unsure about any step in the process or encounter a more complex issue, don’t hesitate to call in a professional plumber.

Identifying the source of a basin leak is the first line of defence against water damage and costly repairs. By being proactive and promptly addressing leaks, you can keep your bathroom in top shape and avoid the headache of more extensive issues.

Prepping for the Fix: Essential Tools

Before diving into your basin leak repair, gather these key tools:

  • Adjustable wrench: This versatile workhorse tackles various-sized nuts and fittings, loosening or tightening them as needed.
  • Basin wrench: Designed for tight under-sink spaces, its long handle and self-adjusting jaws grip and turn those hard-to-reach faucet nuts.
  • Phillips head screwdriver: Keep this handy for tightening or loosening screws that hold faucet handles in place.
  • Flathead screwdriver: This tool goes beyond just turning screws. It can pry apart stubborn faucet components or remove damaged washers.
  • Pliers (adjustable or channellock): When an adjustable wrench won’t budge a stubborn nut or fitting, pliers with their gripping jaws provide extra leverage.
  • Bucket: Leaks happen! A bucket catches drips and spills, keeping your work area clean and preventing water damage.
  • Flashlight: Those cramped under-sink areas can be shadowy. A flashlight illuminates the workspace, ensuring you don’t miss a crucial detail.
  • Rags: Leaks and repairs often mean water. Keep a few rags on hand for wiping up spills and cleaning surfaces as you work.

With this arsenal assembled, you’re well-equipped to tackle most basin leak repairs!

Safety Precautions

Working with plumbing can lead to unexpected hazards. Prioritise safety to prevent injuries and property damage. Here are key precautions:

  • Turn off the water supply before repairs. Locate the shut-off valves under the basin or near the wall.
  • Wear eye protection to shield yourself from splashes or debris.
  • Consider gloves to protect your hands from sharp edges and cleaning products.

Remember, detailed repair instructions depend on your leak source. Refer to a separate guide for specific steps. Common fixes include replacing washers, tightening connections, or resealing drains. Remember to follow instructions carefully to prevent further complications.
