What equipment should a professional drainage engineer have? +
A properly equipped drainage engineer should have high-pressure water jetting equipment (typically 3,000+ PSI), a CCTV drain camera for surveys, electro-mechanical cleaning machines, drain rods, and root cutting attachments. They should also carry personal protective equipment (PPE) including gloves, eye protection and waterproof clothing. Be wary of anyone who turns up with just a set of drain rods — they will struggle with anything beyond a minor blockage.
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 Bristol to clear the blockage.
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 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 Bristol gives you confidence that the work will be carried out to professional standards with proper equipment.
What should I do if sewage is backing up into my home in Bristol? +
Stop using all taps, toilets and appliances that discharge into the drains immediately. Open windows for ventilation as sewage gases are hazardous. Do not attempt to clear the blockage yourself if raw sewage is involved — it carries serious health risks including E. coli and other bacteria. Call an emergency drainage engineer in Bristol straight away and keep children and pets away from the affected area.
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 Bristol. 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.
