Drainage emergencies do not wait for convenient timing. A sewage backup at midnight, a flooded kitchen on Christmas morning, or an overflowing manhole during the school run are all situations our engineers attend regularly across Chester. The actions you take in the first few minutes after discovering the problem can make a significant difference to the amount of damage your property sustains and the cost of putting things right.
How to Tell It Is a Genuine Emergency
Not every slow drain warrants an emergency callout, but the following situations require immediate professional attention:
- Sewage or foul water rising through internal drains into your home
- Significant water flooding from external manholes, gullies, or inspection chambers
- Multiple fixtures throughout the house blocked or draining backwards simultaneously
- A strong, persistent sewage odour inside living areas
- Visible sewage pooling in your garden, on your drive, or on a shared path
Chester properties along the River Dee floodplain, including parts of Handbridge and the Meadows, face an additional risk: when river levels rise, surface water drainage systems can become overwhelmed, causing localised flooding that compounds any existing blockage in your private drainage system.
Steps to Take Immediately
Stop All Water Use
As soon as you realise the drainage system is blocked or backing up, stop adding water to it:
- Do not flush any toilet
- Do not run taps, showers, or baths
- Switch off the washing machine and dishwasher if they are mid-cycle
- If possible, turn off any automatic appliances that discharge water, such as water softeners
Every additional litre of water you put into a blocked system forces wastewater further into areas where it can cause damage.
Protect Your Belongings
If water or sewage is entering your home:
- Move furniture, electronics, and irreplaceable items away from the affected area
- Lift rugs and carpets off the floor
- Roll up curtains and soft furnishings that could absorb contaminated water
- Place towels or plastic sheeting along doorways to contain the spread
- Open windows to ventilate, especially where you can smell sewage, as the gases can be harmful in enclosed spaces
Locate and Turn Off Your Stopcock
If clean water is contributing to the flooding, for example from a burst internal pipe feeding a toilet cistern, locate your stopcock (typically under the kitchen sink or near the front door in Chester houses) and turn off the mains supply. This will not stop the drainage backup but will prevent fresh water from making it worse.
Stay Clear of Contaminated Water
Sewage carries bacteria including E. coli, salmonella, and other pathogens. Keep children and pets well away from affected areas. If you must enter a flooded room to rescue valuables or turn off electrics:
- Wear rubber boots and waterproof gloves
- Avoid touching your face
- Wash your hands and any exposed skin thoroughly with antibacterial soap afterwards
- Do not eat or drink in the contaminated area
Record Everything for Insurance
Once you have done what you can to limit the damage:
- Take photographs and video of every affected area, including close-ups of water levels and damage to fixtures, flooring, and belongings
- Note the date, time, and sequence of events
- Keep a written list of damaged items with approximate values
- Retain any receipts for emergency cleaning supplies or temporary accommodation
Chester-area insurers will expect evidence to support a claim, and the more detail you provide at this stage, the smoother the process will be.
Common Mistakes to Avoid
Do Not Pour Chemical Drain Cleaner into a Backed-Up System
Chemical products are formulated for minor partial blockages, not emergencies. In a fully blocked system, the chemicals sit in the stagnant water creating a corrosive hazard and can react dangerously with sewage. They will not clear a major obstruction.
Do Not Attempt to Open or Enter a Main Sewer
The shared sewer beneath your street is the responsibility of United Utilities in the Chester area. Attempting to access it yourself is potentially dangerous and may breach regulations. If the blockage turns out to be in the public sewer, United Utilities will deal with it at no charge once notified.
Do Not Wait and Hope It Resolves
Drainage blockages do not fix themselves. Delaying action allows more water damage to occur, increases the risk of mould developing, and can turn a straightforward clearance job into a major repair project.
While You Wait for the Engineer
- Clear access to external manholes and inspection chambers; move bins, garden furniture, or vehicles if they are in the way
- Note exactly where water is coming up or backing in, which fixtures are affected, and whether the problem appeared suddenly or has been building
- Ask your neighbours whether they are experiencing similar issues; shared problems point to a blockage in the public sewer rather than your private drainage
