Rats are strong swimmers and are perfectly capable of travelling through sewer and drainage systems. In Stowmarket, as in most towns, an intact drainage system is not usually a problem, but cracks, broken pipe joints or damaged inspection covers can give rats a direct route from the sewer network into gardens and, from there, into homes.

How rats use damaged drains

A drain in good condition is largely rat-proof. Once a pipe cracks, a joint fails, or a rodent trap or non-return valve within the system is missing or faulty, rats can climb up through the gap and emerge at a manhole, gully or broken inspection cover in your garden. From there, it is often a short journey to an air brick, a gap around pipework, or an open door.

Signs your drains may be involved

Rat activity concentrated near an inspection cover or gully, an unusual smell around a manhole, or droppings appearing close to drainage points can all point to drains as the entry route. A drop in water level in a toilet bowl, or scratching sounds from that area, is sometimes reported too.

What can be done

A proper inspection looks at the areas around your property where drains surface, alongside the more usual entry points, to build a full picture of how rats are getting in. Where a damaged drain is suspected, this may need investigating further, alongside treatment of the immediate infestation and advice on rat-proofing the areas around it.

Older drainage systems around Stowmarket

Parts of Stowmarket have drainage systems that have been in place for many years, and age alone can be enough for joints to weaken or pipework to shift slightly over time, particularly where tree roots are nearby. This does not mean every older property has a drainage problem, but it is a factor worth bearing in mind if rat activity seems to be concentrated near a manhole, gully or inspection chamber rather than spread across the property generally.
