A burst pipe has flooded homes and caused disruption to water supplies in Birmingham.
Severn Trent said a "handful of properties" were affected by flooding on Bristol Road South in Northfield in the early hours.
Customers in nine postcodes have been affected but a "large proportion" should find their supply is back to normal, a spokeswoman said.
Some customers were without water, while others experienced low pressure.
Bottled water has been sent to customers while repairs are carried out, Severn Trent said.
Severn Trent said the repair "will be a lengthy progress and is likely to go on for a few days" and a lane closure on Bristol Road will remain in place while the repair is carried out.
On Sunday afternoon, the water company said pressure had been restored for the "majority" of customers but some were still experiencing "intermittent supplies".
The spokeswoman added: "Our teams are working really hard to get everything back to normal as quickly as we can and we want to thank everyone for their patience."
Customers in the following postcode areas have been affected: B14, B15, B16, B28, B29, B30, B31, B45, B90.
