@harry_millerrr: 🛠️ Old cast iron sewer stacks don’t last forever. This one was heavily scaled with years of rust and buildup restricting the pipework. Using specialist descaling equipment, we removed the rust and restored the pipe’s internal diameter, helping improve flow and extend the life of the existing sewer line. 💧 ✅ Cast iron pipe descaling ✅ Improved drainage flow ✅ CCTV inspected before & after ✅ Sydney-wide service 📞 Contact Mr Drains for expert drain cleaning, inspections and repairs. #MrDrains #DrainCleaning #PipeDescaling #CastIronPipes #BlockedDrains
