A step by step guide to isolating your mains water in an emergency.

How to isolate your mains water.

How to Guide

In an emergency, knowing how to turn your water off at the mains can be invaluable and prevent further damage being caused to your property. Referred to as your stop valve, stop tap or stopcock, this  is the main source of operating and ceasing water function to your home.  It is the responsibility of the homeowner or tenant to ensure that the stop valve is installed, maintained, and repaired as needed.

The stop valve will be found inside the home and in many cases can be found near to where the water pipes are situated. This can be near the kitchen sink, the airing cupboard, next to the front door, under the stairs, in a utility room or possibly in a cellar or utility room.

In some office buildings or blocks of flats a stop valve may be shared between those in adjoining flats or offices. Again, this can usually be found where the water enters the building. A stop valve can also be observed in the individual flats or offices in most cases.

It is essential to acquaint yourself with the whereabouts of this stop valve in case of an emergency.

In the event that you need to turn your water off, locate the stop vale and turn it clockwise (to the right). Continue to turn until the water stops completely or the valve won’t turn any further. Do not continue to turn once it comes to a natural stop, some water may continue to flow for a short time due to water pressure.

At Fixx, we would recommend checking your stop valve every few weeks just to ensure that this is working properly and can be quickly turned off in an emergency.

When you need to turn your water back on, simply turn the stop valve anti-clockwise (to the left). It can take a short while for the water to come through the pipes again, but your water will begin to flow as normal.
