Do You Need a CCTV Drain Survey? Signs to Look For

CCTV Drain Surveys — Not Just for Buying a House

Most homeowners associate CCTV drain surveys with property purchases — but there are several everyday situations where a camera inspection is the most efficient way to find out what's happening underground. A survey sends a waterproof camera through your drains via the nearest inspection chamber, recording live footage that pinpoints exactly what's wrong and where.

1. The Drain Keeps Blocking

A one-off blockage caused by grease or hair won't come back once cleared. A drain that blocks again within a few weeks of clearing has a structural cause — root intrusion, a displaced pipe section creating a low point, or a partially collapsed pipe. Jetting alone won't fix it permanently. A camera survey finds the cause before we recommend a solution. Read our full guide to CCTV drain surveys for more detail.

2. Multiple Drains Are Slow

If your sink, bath, and toilet are all slow simultaneously, the blockage is in the shared main drain, not individual appliance pipes. This is much harder to locate and clear without a camera. A survey identifies the exact position so the engineer can target it precisely rather than guessing.

3. Persistent Smell

A sewage smell from drains, or in the garden above the drain run, usually indicates a cracked or displaced pipe allowing gas to escape. A camera survey confirms whether the smell is from a broken pipe or a blocked trap — both have different solutions.

4. Buying a Property

A standard homebuyer's survey doesn't inspect the drains. In Peterborough, where many older terraces and semis have original clay drain runs, a pre-purchase survey is strongly recommended. A failed drain is a significant hidden cost — repairs can run to thousands of pounds. Survey findings can be used to renegotiate on price or request repairs before completion.

5. Planning an Extension

Before any significant building work, you need to know where your existing drains run. Excavating into an unmarked drain during building works is a common and expensive mistake. A survey maps the run and identifies any existing issues before they become a builder's problem.

When You Can Skip the Survey

If it's a straightforward, first-time blockage in a single drain, try drain jetting first. A CCTV survey adds cost and isn't necessary for every blocked drain — it becomes worthwhile when the problem is persistent, structural, or unknown.
