The service restores normal wastewater flow, helps prevent flooding around your property, and confirms the drain is working properly before the job is signed off. ## What gully trap clearance covers Gully traps collect wastewater from sinks, baths, showers and appliances before it enters the main drain. When they block, problems can escalate quickly. This service typically includes: - Locating the affected gully trap and checking connected pipework - Identifying the likely cause, such as leaves, silt, grease, wipes or scale - Clearing the blockage using appropriate tools and methods - Flushing and testing to confirm free-flowing drainage - Checking for signs of recurring issues, damage or poor fall - Practical advice to reduce the chance of repeat blockages ### When this service is the right fit Arrange gully trap clearance if you notice slow draining fixtures, gurgling, persistent drain smells outdoors, or water backing up in the gully. It is also suitable when the gully overflows during heavy use or rainfall, or after building work where debris may have entered the drain. ### How the service is delivered The visit starts with a quick assessment of symptoms and the gully location. The blockage is then cleared and the system is tested by running water through the affected waste lines to confirm the restriction has been removed. If the problem suggests a deeper drain issue, you will be told what was found and what the next step would be. ### After clearance: keeping drainage reliable Once flow is restored, you will be advised on simple prevention, such as keeping the grating clear and avoiding disposing of fats, wipes and solids into sinks or toilets. If there are signs of recurring blockages, you may be recommended further investigation or maintenance to avoid repeat call-outs.

Common signs include slow draining sinks or baths, bad smells outside, and water sitting in or overflowing from the gully. You may also notice gurgling noises or damp patches near external walls. What usually causes a gully trap blockage? Blockages are often caused by leaves, silt, food waste, grease, wipes, or scale buildup in the pipework. Sometimes the issue is linked to a partial collapse, poor pipe fall, or a downstream restriction. Can I clear a gully trap myself? You can try removing surface debris and flushing with water, but avoid forcing tools down the pipe as this can damage fittings. If there is overflow, repeated blockage, or strong odours that return quickly, professional clearance is the safer option. Will you confirm the drain is clear before you leave? Yes, the clearance is followed by flushing and functional checks to confirm normal drainage has been restored. If testing suggests a deeper issue, you will be told what was found and what further work may be needed. How can I prevent the gully trap blocking again? Keep the gully grate clear of leaves and debris and avoid tipping fats, oils and food waste down the sink. Do not flush wipes or sanitary items, and act early if you notice slow drainage or smells returning.
