“Ah,” Dai said, pointing at the monitor. “The classic ‘FOG’ clog.”
Dai’s team arrived with a “call out” marked urgent. Using a powerful vacuum truck (a "hydro-vac"), they sucked the standing sewage away. Then came the CCTV camera. Deep underground, in a section of pipe laid in the 1920s, a section of the brickwork had collapsed, creating a dam of rubble and sludge. blocked drains telford
For Bill, the thought of digging up his prize-winning rose garden was a tragedy. But Dai offered a solution: trenchless pipe relining. A resin-saturated liner was inserted into the old clay pipe, inflated, and cured into a new, smooth, joint-less pipe inside the old one. The roses were saved. “Ah,” Dai said, pointing at the monitor
“Clay pipes are like a magnet for tree roots,” Dai said. “The joints shrink over time, leaving a tiny gap. A root finds that gap, follows the moisture and oxygen into the pipe, and then it branches out. You can jet them out, but they grow back. The real fix is a structural repair—either a patch liner or digging up the old pipe and replacing it with modern plastic.” Then came the CCTV camera
“Fats, Oils, and Grease,” Dai explained. “When you pour bacon fat down the sink or rinse a pan with oil, it’s liquid when hot. But as soon as it hits the cold pipe under your kitchen, it solidifies. Over months, it builds up like concrete. It catches food scraps, coffee grounds, and eventually, you get this.”
