Control the problem. Clear the restriction. Check the flow.
Stop using water that feeds the affected drain where practical. When you call, explain whether the problem affects one fitting or the whole property, whether wastewater is overflowing and when it began. This helps us assess the likely location and suitable equipment.
The clearance method depends on the pipework and cause. Mechanical clearance may suit a local obstruction; high-pressure jetting can remove grease, silt, scale and heavy build-up. If a blockage keeps returning, a CCTV drain survey can help identify roots, displaced joints or damaged pipework.
