Case Study: Emergency Toilet Blockage - City of London (EC2)
A commercial office near Moorgate called for an urgent toilet blockage affecting multiple staff floors. Our team attended the same morning and traced the issue to a build-up in the main WC stack. We cleared the blockage using mechanical rodding and high-pressure jetting, ensuring the toilets were operational before the lunchtime rush. No excavation was required, and the facilities manager received preventative advice to reduce future issues.
Common Signs of a Blocked Toilet
- Water rising high in the bowl when you flush
- Toilet draining very slowly or not at all
- Gurgling sounds coming from the toilet or nearby drains
- Waste backing up into the toilet or shower
- Unpleasant smells around the WC, bathroom or hallway
Case Study: Blocked Toilet in a Flat - Southwark (SE1)
A tenant in a Southwark flat reported a toilet that had become completely blocked, with water close to overflowing. Our engineer arrived within two hours, isolated the water supply and carefully cleared a build-up of wipes and sanitary products from the WC line. Once clear, the system was tested several times to confirm normal flow, and advice was given on what should and should not be flushed.
How We Unblock Toilets
- Assessment: We inspect the toilet and surrounding pipework to identify the likely cause and location of the blockage.
- Clearing the Blockage: Using specialist tools such as mechanical rods or high-pressure water jetting to remove the obstruction safely.
- CCTV Check (if needed): If the blockage keeps returning, we can carry out a CCTV drain survey to confirm the line is clear and identify any defects.
- Testing & Advice: We test flush the system to ensure free-flowing drainage and provide advice to help prevent future toilet blockages.
Case Study: Blocked Customer Toilets - Restaurant in Clapham (SW4)

Our engineer attended promptly, located a heavy build-up of fat and tissue in the shared waste line and cleared it using high-pressure jetting. The toilets were restored to full use the same night, with minimal disruption to trading.
