Southampton homes without water
Hundreds of homes in Southampton were left without water after an airlock blocked part of the supply system.
Southern Water said customers in the SO15 and SO16 areas had called since lunchtime to report problems.
The water company said the airlock occurred during maintenance work on Thursday.
Engineers worked throughout the afternoon to fix the problem and supplies were restored by about 19:00 GMT.
A spokesman said: "When supply is restored to customers' taps, they may experience some harmless discolouration of their water which can be easily resolved by running the tap until the water runs clear."
