The Isle of Man Water Authority says customers in the Farmhill, Crosby and Glen Vine areas should now have their water back on.
A burst main in Glencrutchery was responsible for the loss of supply, but it's now been isolated and is being repaired.
As a consequence of the disruption to the distribution system, some customers may experience some air in the supply and/or discoloured water.
Anyone who requires assistance should contact the Water Authority on 695999.
