What Should You Do During a Drainage Emergency Before Help Arrives?

Step-by-step guidance to protect your property and stay safe while you wait for our rapid response team.

Keith, Owner | Updated July 2026

During a drainage emergency, turn off your main water supply if it is safe to do so, stop using every sink, toilet and appliance in the property, keep clear of any contaminated water and avoid chemical drain cleaners. Then call a professional drainage company straight away. Acting quickly limits flooding, protects your health and reduces the risk of lasting damage to your property.

A+ Drainage Services provides 24/7 emergency drain unblocking across Essex, London and the M25 corridor, and we aim to be with you within the hour. Here is exactly what to do while you wait for us to arrive.

What Should I Do in a Drainage Emergency? (Step by Step)

Follow these steps in order to keep the situation under control before your drainage engineer arrives:

1

Turn off your main water supply

If it is safe to reach, shut off the stopcock to stop more water entering the system and making the flooding worse.

2

Stop using water throughout the property

Do not run taps, flush toilets, or use washing machines and dishwashers, as every litre of wastewater has nowhere to go and will add to the backup.

3

Keep away from contaminated water

Waste water can carry harmful bacteria. Keep children and pets clear, and wash thoroughly if you come into contact with it.

4

Move valuables and lift soft furnishings

Protect belongings, rugs and electrical items near the affected area to limit damage.

5

Do not use chemical drain cleaners

If wastewater backs up, these chemicals can splash and cause skin burns, and they rarely clear a serious blockage anyway.

6

Ventilate the area if you can

Open nearby windows to reduce odours and improve airflow while you wait.

What Counts as a Drainage Emergency?

A drainage emergency is any blockage or fault that risks flooding, property damage or exposure to waste water. Common examples include: sewage backing up into sinks, baths or toilets; wastewater overflowing from an external drain or manhole; a toilet that overflows every time it is flushed; and multiple fixtures blocking at once. If waste water is rising and you cannot stop it, treat it as an emergency and call for help immediately.

What Should I Avoid Doing in a Drainage Emergency?

Some quick reactions make the situation worse. Avoid these common mistakes:

Do not keep flushing or running water to test whether the blockage has cleared, as this adds to the overflow.

Do not pour boiling water or chemicals down the drain, as they can crack pipes or cause burns.

Do not attempt to lift a heavy, sealed manhole cover yourself if waste water is under pressure behind it.

Do not ignore it overnight. A blockage left to build up can turn a manageable clearance into a costly flood.
