Introduction
Blocked drains are a common and often avoidable problem. From kitchen sinks to main runs, blockages cause bad smells, slow drainage, and sometimes backups that require emergency drain unblocking. The good news is that many blockages can be prevented with simple habits and occasional maintenance. This guide outlines practical steps you can take at home to keep your drains flowing and reduce the need for professional unblocking. If you do run into a stubborn blockage, we offer drain unblocking and high-pressure jetting across the UK, including in Uxbridge and Kingston.
What Causes Blocked Drains?
The main culprits are fat, oil, and grease (especially from kitchens), wet wipes and other non-flushable items, hair and soap in bathrooms, tree roots growing into pipes, and debris such as leaves or soil entering gullies. Once a partial blockage forms, it tends to get worse until the drain is fully blocked. Preventing these materials from entering the system, or dealing with roots and structural issues early, can avoid most blockages.
Kitchen: Avoid Pouring Fat and Grease Down the Sink
Fat, oil, and grease solidify as they cool and stick to the inside of pipes. Over time they build up and restrict flow until the drain blocks. Wipe pans and plates with kitchen roll before washing, and put fat and grease in the bin or a sealed container rather than down the sink. Use a sink strainer to catch food scraps and empty it into the bin. These simple steps greatly reduce the risk of kitchen drain blockages and the need for jetting or unblocking.
Bathroom: Use Drain Guards and Only Flush the Right Things
Hair and soap can combine to form stubborn blockages in shower and bath wastes. Fit drain guards or hair catchers and clean them regularly. Only flush toilet paper and human waste down the toilet; wet wipes, sanitary products, and other items should go in the bin even if they are labelled "flushable." These products are a major cause of blocked drains and sewer problems. Teaching everyone in the household to follow these rules will cut down on blockages and callouts.
Outside: Keep Gullies and Gutters Clear
Gullies and surface water drains can block with leaves, mud, and debris. Clear leaves from gratings and gutters regularly, and avoid washing soil or rubble into gullies. If you have trees near your drain runs, be aware that roots can invade pipes and cause blockages; a periodic CCTV survey can spot root ingress before it becomes severe. Keeping external drains clear reduces the chance of backups and flooding.
When Prevention Isn't Enough
If you already have a blockage, or if drains are slow despite good habits, the cause may be further down the line—a build-up of grease, roots, or a structural problem. In that case, a CCTV survey will identify the cause, and we can then jet, clear, or recommend repair as needed. For urgent blockages or backups, our emergency drainage team is available 24/7.
