Another common problem is blockages. These can be caused by a build-up of sediment, grease, or hair. In some cases, blockages can also be caused by tree roots growing into the pipe. If you have a blockage, you’ll need to clear it before you can use the pipe again. Repairing leaks and blockages can be a difficult and time-consuming task. However, it’s important to carry out the repairs as soon as possible to avoid further damage to your pipes.
