Looking after your drainage pipes after the lockdown


When the lockdown was announced, you may have closed your business quickly. If your business involves running a kitchen, you may not have had time to carry out your normal cleaning and maintenance regime.

The length of the closure may mean that your drains and pipes have a build-up of waste on them, and that your equipment that stops fat, oil and grease getting into pipes may not have been cleaned for some time.

To make sure you can get your business up and running again, and avoid sewer blockages that could cost you money, follow these steps:

  • Clean your equipment – before you start cooking, make sure your grease management system is thoroughly cleaned in line with the manufacturer’s instructions.
  • Check your drains and sink gullies – if the drains and sinks haven’t been used for some time, they could have dried up and have waste stuck in them. Check your sink gullies for any blockages and flush your drains through with water. You could also use a bio-dosing liquid or liquid fatbuster as you prepare to reopen, however, this should not take the place of a grease management system when you are operating again.
  • Use sink strainers to stop waste getting into drains and pipes – this is best practice and stops waste clogging up your pipes.
  • Remind your kitchen team to use bins for food waste, and to avoid putting fat, oil and grease down the drains and sinks.
  • Check your toilets – flush your toilets several times to ensure they are still flowing.
