South East Water: No water for homes 'a little longer'
Some of the 3,000 homes in East Sussex without water since Tuesday will see supplies restored later, according to South East Water.
The bursts were all on the main supplying a service reservoir in Kent.
Properties in the Ticehurst, Hurst Green, Robertsbridge and Mountfield areas are affected.
A South East Water spokesman said: "It will take a little longer before all customers have their supplies restored."
The water company said teams had worked through the night and completed a number of repairs to the burst pipeline.Low water pressure
The spokesman said: "There is a lot of air in the system which we need to carefully remove."
Water has been delivered to vulnerable people and customers with medical or special needs and bottled water is available at sites across the area.
About 3,000 properties may have no water or low water pressure, South East Water said.
The company said the bursts were all on a pipeline taking water from a water treatment works at Crowhurst Bridge to a service reservoir in Flimwell.
The first burst at about 16:00 BST on Tuesday was followed by a second at 02:00 BST on Wednesday and then a third at about 15:30 BST.
