Slow Drainage Investigation

What a slow drainage investigation covers

This service is designed for situations where the cause is not obvious, or where problems keep coming back. It typically includes:

• Checks to identify where the restriction is forming (at the trap, branch pipe, or further along the run)
• Investigation of symptoms such as gurgling, bad smells, back-ups or overflow
• Clearing the blockage using the most suitable method for the pipe type and location
• Confirmation testing by running water and checking flow and drainage speed
• Clear feedback on what was found and what to do next if further work is recommended

When this service is right for you

Book an investigation if you notice slow drainage in one or more fixtures, especially if basic DIY steps have not helped. It is also a good fit for recurring blockages, unpleasant odours, or when multiple outlets are affected and you want a proper root-cause fix rather than a quick temporary improvement.

What happens on the day

You will be asked a few questions first to narrow down the likely causes, then the pipework and connections are checked to pinpoint the restriction. The blockage is cleared with appropriate tools for the situation, and drainage is tested afterwards to confirm normal flow has been restored. If the issue suggests a deeper problem (for example, a collapsed pipe or ongoing ingress), you will be advised on the next sensible step.

Aftercare and next steps

Once drainage is back to normal, you will receive practical guidance to reduce repeat blockages and protect the pipework. If further investigation is needed, you will be given a clear explanation of the options and what each would achieve before any additional work goes ahead.
