Drain Backflow
Drain backflow occurs when wastewater reverses direction and comes back up through your drains, toilets, or manholes. This is both a health hazard and a sign of a serious blockage or structural failure in your drainage system. Immediate professional attention is essential.
What to Look For
- Sewage coming up through floor drains or shower trays
- Toilet water rising when other fixtures are used
- Manholes overflowing in the garden
- Foul water appearing in sinks or baths
- Backflow that worsens during heavy rainfall
- Multiple fixtures affected simultaneously
How We Diagnose the Problem
We attend as an emergency to contain the backflow, then use CCTV cameras to locate the blockage or failure point. Common causes include main drain collapses, severe root blockages, fat buildup, or problems in the public sewer system causing backflow into private drains.
Think you might have drain backflow? A professional inspection will confirm the diagnosis.
How We Fix It
We clear the immediate blockage with high-pressure jetting, then repair any structural damage found. For properties prone to backflow from the public sewer, we can install non-return valves to prevent future incidents. All work includes a CCTV verification survey.
