When you're experiencing no water or poor pressure, there are a couple of simple tests you can complete at home to try and restore your supply. Watch the video or read the information below to find out more.

How you can test your water supply at home

Check your internal stop tap - Locate your internal stop tap (this is usually under the kitchen sink) and turn it off and back on 4-5 times, whilst running your cold kitchen tap. This will clear any blockages in the pipework and your pressure should return to normal.

Carry out a flow test - Regulation guidelines are that there should be 10 metres head of pressure at the boundary, with a flow of 9 litres per minute. This is equivalent to you running your cold kitchen tap to fill a 1 litre container in 7 seconds. If you fill the container within 7 seconds this means your pressure is above our standards of service.

You may see fluctuations in pressure due to peak times of the day when there’s a higher demand for water. For example, between the hours of 7am – 9am when most of us are up and getting ready for the day. Or of an evening around 4pm-7pm, when more people are at home preparing dinner or making a brew.
