Disclosed is a method for remote estimation of the hydrant water pressure at a hydrant (1) located at the end of a branch pipe (2) being branched of a main pipe (3). The method comprises the steps of - detecting a valve open-close status of a stop valve (4) arranged in the branch pipe (2) and transmitting the valve open-close status wirelessly to an external data system (5), - detecting a hydrant open-close status of the hydrant (1) and transmitting the hydrant open-close status wirelessly to an external data system (5), - detecting a branch water pressure of water in the branch pipe (2) and transmitting the branch water pressure wirelessly to the external data system (5), and - estimating the hydrant water pressure at the hydrant (1) based on the valve open-close status, the hydrant open-close status and the branch water pressure. A hydrant water pressure estimation system (7) for remote estimation of the hydrant water pressure at a hydrant (1) located at the end of a branch pipe (2) being branched of a main pipe (3) is also disclosed.
