Some homeowners in Pearl River are still being urged to boil water before use.
SUEZ Water officials say the break happened around 2 a.m. on Sunday, and caused a loss of pressure in the distribution pipes.
The depressurization then increases the chance that untreated water could enter the system.
They say the boil water order is in effect for many of the homes on Michael Roberts Court, Robert McPadding Street, Fred Ill Jr. Court, Blue Hill Plaza and Veterans Memorial Drive.
Officials urge residents not to drink the water until boiling it for at least one minute.
The boiled water should be used for drinking, making ice, brushing teeth, washing dishes and prepping food.
Neighbors say they are sticking to bottled water for now.
"We did get pressure back so I thought everything was fine.
We are still doing bottled water, I didn’t want to take the chance," says one homeowner.
The boil water advisory will remain in effect until officials finish testing and deem the water safe.
