How often should I have my drains surveyed? +
For most domestic properties, a CCTV drain survey every 3 to 5 years is sufficient to catch problems early. If you have mature trees near your drains, older clay pipes, or a history of blockages, consider annual surveys. You should also commission a drain survey before buying a property — it can reveal expensive problems like collapsed sections or root intrusion that are not visible from the surface.
What causes a foul smell from my drains in Edinburgh? +
Foul drain smells are usually caused by a dried-out trap (the U-bend), a cracked or disconnected pipe, or a blockage building up in the system. If the smell is coming from outside, it could indicate a broken manhole cover seal or a collapsed section of drain. Run water through any infrequently used sinks or showers to refill their traps first. If the smell persists, a CCTV drain survey will identify the cause.
Can I unblock my own drain or should I call a professional? +
Simple blockages near plugholes can sometimes be cleared with a plunger or drain snake. However, if you have sewage backing up, multiple drains blocked at once, or persistent foul smells, you should call a professional drainage engineer in Edinburgh. Using chemical drain cleaners on severe blockages rarely works and can damage older clay pipes. Professional high-pressure jetting is far more effective and safer for your drainage system.

What is the NADC and why does it matter? +
The NADC — National Association of Drainage Contractors — is the leading UK trade body for drainage professionals. NADC members must demonstrate competence, carry appropriate insurance, and adhere to a code of practice. Choosing an NADC-registered drainage engineer in Edinburgh gives you confidence that the work will be carried out to professional standards with proper equipment.
What is the difference between a drain and a sewer? +
A drain serves a single property and runs from your house to the boundary. A sewer carries waste from multiple properties and is maintained by the water company. Lateral drains — the section connecting your drain to the public sewer — transferred to water company responsibility in October 2011. Understanding this distinction matters because it determines who pays for repairs.
