The burst main affected people in Oldbury, more specifically those in the B68 area.
Repairs were carried out by South Staffs Water in Bamford Hill Close and were completed by 3.30pm.
The issue is said to have been caused by third party damage to one of the mains.

Pearl Beniston, who works as as a dog groomer at her business Pearl's Groom Room, in Oldbury, said the burst pipe was likely going to result in her having to cancel her afternoon appointments.
