In this video, we will teach you how to seal up a water leakage.

Repairing a water leakage can avoid water damage occurring that would require significant plumbing or masonry works

Before beginning any plumbing work, ensure that the water is turned off at the mains.

To seal a leakage, you will need: a metal brush, a cloth, a Stanley knife, medium-grit sandpaper, methylated spirits, self-fusing anti-leak tape, leak-sealing plumber's putty.

STEP 1: Preparing the pipe

Carefully wipe down the pipe.

Clean it with medium grit sandpaper.

Scrub it with a metal brush to remove possible traces of rust or paint.

Degrease the pipe by rubbing it with the cloth soaked in methylated spirits.

Leave it to evaporate for 5 minutes.

STEP 2: Using self-fusing anti-leak tape

Carefully stretch out the self-fusing tape.

Wind the tape all the way around the duct, carefully stretching it over itself. Stick it on around the pipe in a spiral , ensuring that each time you go around the pipe, you cover half of the previous circle of tape.

The taped area should cover the leakage area plus a few centimetres on either side.

Leave it to dry for a few minutes and turn the water back on.

Step 3: Using the putty

Tip: For copper pipes, plumber's putty is preferable.

Carefully clean the pipe, as outlined earlier,

Using the Stanley knife, cut off a piece of putty.

Knead the putty well between your fingers until both components are perfectly mixed together.

Place the putty ball right on the leakage area. Flatten it so as to make it stick to the pipe.

Leave it to dry for 24 hours.

To finish, ensure that the leakage is gone.

To do this, turn the water on again.

Make sure that water is no longer leaking from around the repaired area.

Now you know how to seal up a leakage.
