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.
Can I build over an existing drain on my property? +
Building over or near a public sewer requires a Build Over Agreement from your water company. For private drains, you do not need permission but you must ensure the drain remains accessible for maintenance. Building Regulations require that drains under or near buildings are adequately protected. A CCTV drain survey before and after construction is strongly recommended to prove the drain's condition.
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 Belfast to clear the blockage.
Are emergency drainage engineers available at weekends in Belfast? +
Yes, most emergency drainage services covering Belfast operate 7 days a week, including weekends and bank holidays. Sewage backups and flooding drains are genuine emergencies that cannot wait until Monday. Expect to pay a premium of around 25% to 50% for weekend and out-of-hours call-outs compared to weekday rates.
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 Belfast. 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.
