When Your Sewer Needs Cleaning
A private sewer connects your property’s drainage to the wider network, and it can cause problems for one property or several sharing the same run.
- Slow-draining fixtures across the property: if multiple drains are backing up at once, the shared sewer connection, not an individual fixture, is usually the cause. This is a useful sign to look out for, since it points straight to the sewer run rather than an individual toilet, sink or bath, saving time spent investigating the wrong fixture. We assess the whole run rather than treating each symptom separately.
- Recurring blockages in older, shared connections: period properties on original clay sewers, sometimes shared with neighbouring homes, are especially prone to this. Where a sewer is shared, a blockage caused by one property can affect all the others connected to it, so it’s worth checking with neighbours if the issue seems to come and go. We can help establish whether your sewer is shared as part of an assessment.
- Bad odours from outside drains: a build-up inside the sewer run often shows up as smell before it fully blocks. This is often the earliest warning sign available, well before any fixture actually stops draining, so it’s worth acting on rather than waiting for a full blockage to develop. A clearance at this stage is usually quicker and less disruptive.
- Routine maintenance: scheduled cleaning keeps a private sewer running freely and catches problems before they become an emergency. This is particularly worth considering for older or shared connections, where the cumulative build-up from multiple households means blockages tend to form faster than on a single-property run.
Thorough Private Sewer Cleaning
At Cooper & Sons Drainage, we clear and maintain private sewer connections using jetting and rodding to remove grease, scale, root ingress and general build-up from the full length of the run. Every call-out is free, so you know what you’re paying before any work starts.
We work on private drainage and sewers only. If a survey or call-out shows the issue actually sits on the public or adopted sewer network, we’ll let you know straightaway and point you to your local water company, who are responsible for that section, rather than carrying out work that isn’t ours to do.
Every completed job is covered by our 1-year guarantee, giving you peace of mind that the fix will hold.
We’re also proud of our reviews from satisfied customers, which you’ll find in the footer below.

Frequently Asked Questions
We always confirm the price before starting work, so there are no surprises on the invoice.
No, we work on private drainage and sewers only. If your issue turns out to be on the public network, we'll let you know and point you to your local water company, who are responsible for that section.
Many period properties share a sewer connection with one or more neighbouring homes. If you're unsure, we can help identify this as part of our assessment or a CCTV survey.
Yes, an out-of-hours surcharge applies.
This depends on the property and connection, older or shared sewers generally benefit from more regular attention. We can advise honestly on what's actually needed rather than pushing an unnecessary schedule.
