1. A method for remote estimation of hydrant water pressure at a hydrant located at an end of a branch pipe being branched of a main pipe, said method comprising the steps of:
detecting a valve open-close status of a stop valve arranged in said branch pipe and transmitting said valve open-close status wirelessly to an external data system,
detecting a hydrant open-close status of said hydrant and transmitting said hydrant open-close status wirelessly to said external data system,
detecting a branch water pressure of water in said branch pipe and transmitting said branch water pressure wirelessly to said external data system, and
estimating said hydrant water pressure at said hydrant based on said valve open-close status, said hydrant open-close status and said branch water pressure.
