If water is uncontrolled or approaching electrical equipment, prioritise safety and call a plumber. The guidance below is general and does not replace an inspection.

Understanding the issue

Drain-cleaning products may remain in trapped water and create a handling hazard. Mixing products can be dangerous. Tell the attending plumber what was used before they open or clear the pipework.

Before arranging the visit

Keep the product packaging available and do not add a second chemical in an attempt to improve the result.
