Wythenshawe residents without gas for four days
It will take "some time" to restore gas supplies to about 1,400 homes in Manchester, the National Grid has said.
Households in Wythenshawe have been without gas for four days after 30,000 litres of water flooded into supply mains when a pipe burst.
Supply was restored to about 100 homes on Wednesday evening, but water is still being pumped from the network.
Engineers need to visit each home to turn the gas back on at the meter and check appliances are working.
The water pipe burst at the junction of Portway Road and Saltrush Road early on Sunday, cutting off gas supplies.
The National Grid Helpline is providing electric cooking rings and heaters to affected residents.
Stephanie Van Rossa, from the National Grid, said: "We've got engineers from the whole of the North West working along with contractors, we've pulled people in.
"We have engineers on the ground who can go in and reconnect people."
The area has been split into seven zones which will be reconnected in turn once the area's gas pipes have been cleared of water.
The company said it was important that people ask to see the identity cards of engineers who call at their home.
A United Utilities spokeswoman added: "Our preliminary investigations have shown that the water main burst at a point where a new gas main had been laid only an inch away."
