Signs that your drainage system needs attention

A warning sign is not a diagnosis

The EA’s England guidance lists sewage smells among signs that a system may not be in good working order. Its examples also include leaks, blocked pipes, pooling near a drainage point and failed equipment. A professional assessment is needed to identify the cause at your property.

Record what you have noticed

• Describe when the issue started and whether it is constant or intermittent.
• Note which part of the property is affected without opening or entering the system.
• Tell the service firm about recent emptying, repairs or changes to occupancy if known.
• Ask whether its proposed visit is diagnosis, emptying, repair or a survey.

Choose the right next contact

• Ask the relevant service company to assess the system and explain whether immediate action is needed.
• If you suspect a discharge is affecting the environment, use your nation’s regulator contact route in the rules guide.
• Do not assume that emptying alone fixes a drainage-field or equipment fault. Ask the professional to explain the evidence for the proposed remedy.

Keep the finding, not just the invoice

• Ask for the identified defect and proposed work in writing.
• Record whether further inspection or permission checks were recommended.
• Avoid DIY tank entry, opening damaged covers or electrical investigation; this page does not teach those tasks.
