When you discover that you have a sink leaking it’s important to get it sorted quickly before it causes too much damage. Whilst some situations require a plumber, there are some leaks which you can easily fix at home. Read on to discover our guide for what to do if your kitchen sink is leaking.If your kitchen sink is leaking underneath, you first need to identify what is causing the leak. Start by clearing out the area under your sink and then check for the following:
A pressurised water hose leak.
Have you got a constant spray? This is likely the cause. You’ll probably find it creates a rather large mess due to its constant flow.
A drain line leak.
If you turn your tap on, and as the water drains away the pipe under sink is leaking, this could be the culprit.
A faulty seal or drain gasket.
If it is neither of the two above issues, it could be that your sink is leaking from a drain gasket or seal which has eroded or come loose. The best way to check this is by filling the sink with water before allowing it to drain away.
Unidentified issue.
If you are still dealing with a leak that does not seem to be identifiable, it is time to call a plumber. They will be able to tell you where the leak is and what needs to be done to fix it.
Next, it is time to fix the leak! Here are our top tips to fix a leak under the sink, with steps for each of the three main leak types we have discussed above.
For a pressurised water hose leak:
Turn off the water.
This leak is in the pipe which carries water to your tap, and so will continue to spray water for as long as the water is on!
Tighten the fittings.
The main cause of an under sink pipe leaking are the fittings around shut off valves, so it should be a simple fix by tightening these up. You need to use a wrench the hold the valve while tightening the compression nut with your hand.
Still leaking? Tighten the faucet connection.
If it is still leaking when you turn the water back on, it could be the connection between the pipe and faucet. Use adjustable pliers to tighten this up.
If these two methods don’t work, call a plumber
