What causes a foul smell from my drains in Altrincham? +
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.
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 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.
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 Altrincham gives you confidence that the work will be carried out to professional standards with proper equipment.
What should I do if my drain is overflowing outside? +
If an external drain or manhole is overflowing, check whether it is a shared drain serving multiple properties. Since October 2011, lateral drains and public sewers became the responsibility of your water company, so contact them first if the blockage is beyond your property boundary. If it is a private drain within your boundary, call a drainage engineer in Altrincham to clear the blockage.
