Blocked drain: what to check before booking help

Safe first steps

1. Stop using fixtures that cause water to rise or overflow.
2. Check whether the blockage affects one sink, one room or the whole property.
3. Keep people and pets away from sewage or dirty standing water.
4. Tell the specialist about odours, noises and any products used.

What not to do

• Never mix different drain chemicals.
• Do not open a manhole if it is unsafe or not on your property.
• Do not keep flushing an overflowing toilet.
