Why arrange for drain inspection if you aren’t having any problems?
Drainage problems generally only come to light when they start to affect us, but that isn’t to say they don’t start before then. If you have never had your drains inspected, it is worth hiring someone to carry out the task as it may prevent major problems in the future.
A standard drain inspection will involve first jetting the drains to clear away any significant debris and then putting a camera through to identify any major problems.
Many things might be found. Something as simple as a build-up of silt will be easily dealt with, while tree roots and broken sections of drain will be more complex. However, the key benefit is that you will be able to address these problems before they get out of hand.
Tree roots will often find a way into a drain as they are searching for moisture. Obviously, what starts as a small root is likely to develop over time and can cause greater structural damage to the pipe as a result. Similarly, a sharp edge inside a drain can lead to a gradual build-up of grime which might ultimately lead to a complete blockage, which will be hugely inconvenient.
Far better to address problems such as these early and the only way to identify them in the first place is by arranging a professional drain inspection.
