Severn Trent Water became aware of the issue at just after 1pm on Wednesday and had a team on site working on the repair.
At 6.15pm a spokesman said: "We’re so sorry if you notice a slight dip in your water pressure in the SY7 area of Shropshire.
"This is due to a burst water pipe at Craven Arms. We have a team on site working on the repair and are confident to have this resolved as soon as possible.
"We really appreciate your patience whilst we work to get this resolved."
