South West Water has apologised after residents in several Devon towns continued to face disruption to their water supply.
The company said engineers were working to fix a problem caused by air pockets in the network serving Buckfastleigh, Paignton, Kingsbridge and Totnes.
A number of people reported issues since Thursday, which were resolved by Friday but returned on Saturday.
South West Water said it was sorry for any inconvenience caused and added that bottled water stations at Meadowbank Car Park in Dartington and the Cattle Market car park in Kingsbridge would be open until 22:00 BST on Saturday and would then reopen at 08:00 on Sunday.

On Friday, South West Water said customers in Buckfastleigh were experiencing a loss of supply or low pressure after "issues with equipment" at one of its treatment works.
The company said air pockets then formed in the network while resolving the issue, which led to supply being impacted again.
"Our teams are working around the clock to remove these and return service to normal as quickly as possible," a South West Water spokesperson said.
"We apologise for the disruption and thank customers for their continued patience and understanding," they added.
South West Water said bottled water would be delivered to its most vulnerable customers.
