An under-sink leak is a common problem that can quickly lead to inconvenience, such as property damage or unpleasant odours. Fortunately, most under-sink leaks can be easily repaired with the right tools and a little method. In this article, you’ll discover some simple and effective solutions for solving this problem quickly.
Identify the source of the leak
Before starting, it’s essential to identify the source of the leak. The most common causes are :
- A worn or loose seal on the siphon
- A loose connection on a drain or water inlet pipe
- A crack or hole in the siphon or pipework
- A leaky faucet, which can run along the pipes under the sink
Carefully inspect the various components to determine the source of the problem. Place a basin under the sink and let the water run to pinpoint the leak.
Solutions for repairing under-sink leaks
Tighten fittings and check seals
In many cases, a leak is caused by a loose fitting. Use a wrench to tighten the fitting nuts. If the problem persists, check the condition of the rubber seals. A worn or deformed gasket must be replaced. Be sure to use a gasket that is suitable for the size of your trap or pipe.
Replacing a faulty siphon
If the leak comes from the siphon and it is cracked or damaged, it will need to be replaced. To do this, proceed as follows:
- Unscrew the siphon by loosening the fixing nuts.
- Remove it and clean the pipe ends to remove residues.
- Install a new siphon, making sure the joints fit tightly.
- Tighten nuts firmly, without forcing, to avoid damaging them.
Repairing cracks with epoxy paste
For a leak due to a minor crack in a pipe or fitting, apply a water-resistant epoxy paste. Clean and dry the affected area before applying the product. Allow to dry completely according to the manufacturer’s instructions before testing the repair.
Replace part of the piping
If a pipe is severely damaged, it may need to be replaced. Turn off the water, remove the damaged section using a pipe cutter or saw, and install a new segment using suitable fittings. Be sure to glue or fasten all components together to ensure a watertight seal.
Preventing future leaks under a sink
To prevent the problem from recurring, perform regular maintenance on your plumbing. Clean traps to prevent residue build-up, tighten fittings if necessary, and replace worn seals at the first sign of deterioration. Also check water inlet pipes for signs of wear and corrosion.
