Some towns and villages on the Norfolk coast were experiencing water supply issues amid the heatwave.
On Monday afternoon, Anglian Water said that some of its customers in Happisburgh, Lessingham and the surrounding areas had very low water pressure.
On the Anglian Water map this shows issues going down as far as Horsey.
The company said that it is due to demand for water being "very high at the moment".
Normal service was resumed at about 7.30pm, after engineers fixed the issue.
It comes as temperatures soar across Norfolk, with some areas nearing 40C.
Ahead of the heatwave, Anglian Water urged households to turn off lawn sprinklers, to not wash their car and to take shorter showers.
