A number of Todmorden residents have been left without water since Sunday.
The problems, around Robinwood Terrace, began on Sunday evening.
A spokesperson for Yorkshire Water said: “We sincerely apologise to the customers in Todmorden who’ve been affected by our burst water main.
“We want to reassure local people that we’ve been working round the clock to make sure we permanently fix the issue as quickly as possible.
“Some customers in the area may have experienced intermittent water supply or low pressure, but we now have a temporary fix in place and water supply should now be restored.”
