Why CCTV is the Best Way to Investigate Drainage Problems

Comments Off on Why CCTV is the Best Way to Investigate Drainage Problems

If you’ve found a drainage problem, you’ll want to deal with it as soon as possible before it causes anymore disruption.

The first step towards sorting it out is determining where the problem is. Accuracy is important if you want to solve the problem quickly.Drainage Problems

But how do you find the source of the problem?

One way to do this is to have a CCTV drain inspection, this will help you accurately pinpoint where the problem lies and bring you one step closer to fixing it.

 

How does it work?

With a CCTV drain inspection, a camera small enough to fit will be fed through the drains. This will provide a live feed to engineers examining the problem on the surface.

It’s useful because it allows engineers to identify and find the problem quickly, potentially avoiding costly and time-consuming replacements.

In order to get ahead and see problems before they arise, regular CCTV inspections are recommended. That way you can see any problems emerging like developing blockages, root ingress or fissures. This will put you in a better position to make a decision on whether to replace any drains before they become major disruptions.

 

Are there any other methods?

 

The toilet flush test

This is probably the simplest method of drain inspection. It involves monitoring what happens to a manhole after running a tap or flushing a toilet. A blocked drain can be quickly diagnosed this way as you’ll be able to see what does and doesn’t come through.

While it’s not an accurate way to find the problem, it’s a good first step. If there looks like there’s a problem, then further investigation will tell you more.

 

The dye test

Another method for checking drains is the dye test. This involves putting certain colour dyes into drainage systems and seeing what colours comes through when doing the toilet flush test.

This can be particularly useful when identifying the source of leaks as it will narrow down the possibilities of which drains are the root of the problem.

It’ll give you more of an idea of the drains affected but you’ll probably have to do more investigating into the problem.

 

The water test

Another method is the water test. This is where you fill up a pipe and block off the exit points. If the water levels stay the same, then this means there aren’t any leaks.

This last method is more complex than doing a CCTV inspection as it means engineers will have to map out your entire drainage system and work out how to isolate each drain.

 

How do CCTV inspections compare?

Compared to the other three common tests, CCTV comes out on top. It’s accurate and therefore allows you to make a more informed choice on the best action to take.

While the other tests can help you narrow down the problem, a CCTV inspection will give you the best chance of accuracy.

It also allows you to see problems develop before they cause too much damage if you decide to do regular inspections.
