We recently attended a commercial property that was experiencing frequently blocked drains. The drains were repeatedly backing up, despite previous attempts to clear them.

Rather than simply clearing the blockage and waiting for the next call-out, we decided to investigate the root cause.

A CCTV drainage survey was carried out, and it revealed exactly why the problem was happening.

The internal pipework was heavily affected by hard, compacted drain encrustation throughout the drainage system. Over time, this had significantly reduced the internal diameter of the pipes and restricted the flow.

And here’s where the trouble starts…

Tissue and waste were catching on the rough, heavily encrusted surfaces inside the pipework, creating the perfect conditions for further build-up and recurring drain blockages.

In simple terms — the pipes were technically still there, but they were becoming more like a straw with a load of concrete stuck inside it!

A standard drain unblocking only treats the symptom.

By carrying out a CCTV drain survey, we were able to identify the underlying problem and provide the property with a much clearer picture of what was actually happening inside the drainage system.

This is why CCTV drainage surveys can be particularly valuable for commercial properties suffering from recurring drainage issues. Instead of repeatedly paying to clear the same blocked drain, identifying the cause allows the correct remedial work to be considered.

CCTV drainage survey completed

Drainage problem identified

Cause of recurring blockages established

Commercial drainage system assessed

Appropriate remedial options can now be considered

If your commercial property is constantly calling someone out for the same blocked drain, there could be a bigger problem hiding within the drainage system.

CCTV Drain Inspection Preston

Client:

Residential

Location:

Preston

Date: August 2026

We recently attended a customer’s property to carry out a CCTV drainage survey. During the inspection, we noticed something important — the property didn’t have an inspection chamber or any suitable external access to the drainage system.

To complete the CCTV survey, we drilled through the soil stack to gain access to the pipework and were able to inspect the drainage system.

Once we’d completed the survey, we recommended installing a new inspection chamber — and that’s exactly what we did.

Why is an inspection chamber so useful?

Having a proper inspection chamber gives you a dedicated access point to your drainage system. If you ever experience a blocked drain or drainage issue in the future, it means we can:

Access the drain much more easily

Locate and diagnose drainage problems more efficiently

Rod and clear blockages from a suitable access point

Carry out a drain inspection and check the condition of your drainage system when required

It may not be something you think about until you have a problem, but having the right access points in your drainage system can save a lot of time, hassle and potentially money further down the line.

In this case, the customer now has a proper inspection chamber that provides easy, reliable access to their drainage system for years to come.

If your property doesn’t have an inspection chamber, it could be worth having your drainage system checked. We can assess the existing layout and advise on the best drainage access solution for your property.
