How do I drain my water system?

Published in Plumbing Basics 2 mins read

Draining your water system is a straightforward process involving a few key steps. Here's a guide on how to do it:

Steps to Drain Your Water System

  1. Turn off the mains water supply: Locate your stopcock (usually under the kitchen sink or where the water enters your property) and turn it off. This will prevent more water from entering the system.

  2. Run all the taps and flush toilets: Open all the taps in your house, both hot and cold, and flush all the toilets. This helps to release pressure and drain the water already in the pipes.

  3. Empty the hot water cylinder:

    • Locate the draincock at the base of your hot water cylinder.
    • Attach a hosepipe to the draincock.
    • Run the hosepipe to a drain or into a large bucket to collect the draining water.
    • Open the draincock to allow the cylinder to empty.
