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 Chichester. 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.
Do slow-draining sinks always mean a blocked drain? +
Not always. A slow-draining sink is often caused by a localised blockage in the waste trap or the pipe immediately beneath the sink — hair, soap scum and grease are common culprits. However, if multiple fixtures are draining slowly or you notice gurgling sounds, the problem is likely further down in the main drain. A drainage engineer in Chichester can distinguish between a simple waste pipe blockage and a more serious drain issue.
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 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 Chichester 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 Chichester to clear the blockage.
Are emergency drainage engineers available at weekends in Chichester? +
Yes, most emergency drainage services covering Chichester 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.
