While it’s a problem that can cause a lot of cosmetic damage, a leak under your sink is fairly straightforward to diagnose and repair. Here are some possible causes:

• Your pipe isn’t fitted correctly

If your pipe isn’t fitted correctly, you’ll need to fix this, using the nozzle to secure it in place.

• Your pipe needs to be changed

Available at most DIY stores, if you find that your pipe is old or damaged it will need to be replaced.

• Your washer needs replacing

If water is leaking from a joint then it is likely that the washer has become ineffective.
