The sewer system beneath your home is one of those things you rarely think about—until something goes wrong. A blocked or damaged drain can quickly lead to damp, unpleasant odours, or even flooding. That’s why it pays to establish a routine for regular sewer inspections. With a few simple habits and scheduled checks, you can prevent costly repairs and keep your drainage system working as it should.

Why Regular Inspections Matter

Your home’s drainage network is hidden underground, but it plays a vital role in keeping your property healthy and safe. Over time, tree roots, grease, silt, and debris can build up inside the pipes, causing blockages. Older pipes may also crack or shift, allowing leaks that can attract rats or cause structural damage.

By inspecting your drains regularly, you can spot early signs of trouble before they escalate. Preventive maintenance is not only cheaper but also more environmentally friendly than dealing with the aftermath of a major fault.

Create a Maintenance Plan

A good routine starts with a clear plan. You don’t need to check your drains every week, but an annual or twice-yearly inspection is a sensible rule of thumb—especially if you live in an older property or an area with many trees.

• Spring and autumn are ideal times for inspections. After winter, frost may have affected the pipes, and in autumn, falling leaves and roots can cause blockages.
• Set a reminder in your calendar so you don’t forget.
• Keep a simple log of your observations and any issues. This helps you track changes over time and spot recurring problems.

Signs That Your Drains Need Checking

Even with a regular routine, it’s important to act quickly if you notice changes in how your drains behave. Common warning signs include:

• Water draining slowly from sinks, showers, or toilets.
• Gurgling sounds coming from the pipes.
• Damp patches or sewage smells in the cellar, garden, or around inspection covers.
• Evidence of rats or their droppings near the property.

These symptoms don’t always mean there’s a serious fault, but they should be investigated before the problem worsens.

How to Carry Out a Basic Check Yourself

You can perform a simple visual inspection of the parts of your drainage system that are accessible:

1. Check inspection chambers and manholes – lift the cover carefully and look for standing water or signs of blockage.
2. Keep gullies and surface drains clear – remove leaves and debris so rainwater can flow freely.
3. Avoid pouring fats, oils, or food waste down the sink – these solidify in the pipes and cause blockages.
4. Use drain strainers in sinks and showers to catch hair and small objects.

If you notice anything unusual, it’s time to call a professional drainage engineer for a CCTV survey.

Get Professional Help Periodically

While you can do a lot yourself, it’s wise to have a qualified drainage specialist inspect your system every few years. A professional can:

• Carry out a CCTV drain survey to detect cracks, root intrusion, or misaligned joints.
• Jet-clean the drains to remove grease and sediment build-up.
• Assess the need for repairs or relining before damage becomes severe.

Although this may seem like an extra expense, it can save you from far greater costs and disruption later on.

Make Drain Maintenance Part of Your Home Routine

Just as you check the roof, clean the gutters, and service the boiler, your drains should be part of your regular home maintenance plan. It doesn’t require much time—just consistency. Once you establish a routine, it becomes a natural part of looking after your property.

By taking responsibility for your drainage system, you not only ensure smooth wastewater flow but also protect your home from damp, odours, and unwelcome surprises.
