Leaky sink? Don’t delay – learn how to fix a pipe leak under a sink. With the right products and some expert tips, you can get it sorted in no time.
Leaky pipes are a common problem and may not seem like an emergency. However, if they’re not dealt with promptly, they can result in significant damage. Even a minor leak should be repaired as quickly as possible.
So, how to seal a leaking pipe?
The good news is you can easily fix uPVC waste pipes yourself using either epoxy putty or a high-strength, waterproof repair tape. With the right products, it’s a simple and straightforward job.
In the sections below we’ll show you exactly how to fix a pipe leak under a sink, so you can protect your home from water damage.
Our top recommendation for pipe leaks is epoxy putty. UniBond Repair Express Power Putty is strong and waterproof, so it’s ideal for pipe repairs. In addition, it is quick and easy to use – no expertise or special tools required! You simply mould the putty and wrap it around the pipe.
As well as the epoxy putty, you’ll need a bucket, a cutting tool, and a pair of gloves.
Here’s how to seal a leaking pipe with putty:
1. Get a bucket. Put a bucket under the sink to catch any leaks and prevent further damage.
2. Turn off the sink’s water supply. The internal stop tap is usually located under the kitchen sink. Turn it clockwise.
3. Clean and dry the surface of the pipe. This will make it easier to apply the putty effectively.
4. Use gloves before and while handling the putty.
5. Cut the epoxy putty. Cut off the amount you need – enough to go right around the pipe.
6. Prepare the putty. For the best results, knead the putty for about a minute.
7. Apply the putty. Wrap it around the pipe, using firm pressure so it adheres to the crack or joint. Hold the putty firmly in place for 3-5 minutes.
8. Wait for the putty to dry. UniBond Repair Express Power Putty sets within 5 minutes, and reaches full strength after 24 hours.
As an alternative to epoxy putty, you can also try a high-quality tape such as UniBond Extra Strong Power Tape. This heavy-duty, waterproof tape is very easy to use, and perfect for temporary fixes. Suitable for a wide range of DIY jobs, it’s a popular choice for pipe repair.
This is how to fix a pipe leak under a sink with UniBond Extra Strong Power Tape:
1. Prepare the pipe surface. It should be clean and dry.
2. Rip off a piece of tape by hand. Make sure it’s big enough to go around the pipe multiple times.
3. Apply the tape. Press it onto the pipe with firm and even pressure. Keeping the tape held in place, wrap it around the pipe a few more times.
Repair tape is intended to be used as a temporary fix. If you later need to replace the pipe, you can remove the tape with a utility knife.
