A number of people suggested that this should be permitted because it is a psik reisha d'lo nicha lei on an issur d'rabbanan. I would like to raise 2 issues with that premise:<br><br>1. Is this really lo nicha lei? Everyone would agree that you cannot disconnect the meter before shabbos and use the water because you would be stealing from the water company. Therefore, the meter recording how much water you used is nicha lei. If the meter didn't record your use the company would not be able to charge you and you wouldn't know how much to pay, in essence you would be stealing. Therefore, you want the meter to record your use to keep you from stealing.<br>
2. It is not so clear that psik reisha d'lo nicha lei on an issur d'rabbanan is permitted. R' Eider in his sefer on hilchos shabbos writes that a psik reisha d'lo nicha lei on an issur d'rabbanan is assur. The Shemiras Shabbos in the new edition has an introduction to Hilchos Shabbos. In the text he doesn't discuss psik reisha d'lo nicha lei on an issur d'rabbanan but in a footnote he quotes a number of Mishna Berura's that it is assur. R' Willig in his sefer Am Mordechai on Shabbos, wanted to make the following distinction by psik reisha d'lo nicha lei on an issur d'rabbanan. He said that if the issur is ikkaro min hatorah and it is only d'rabbanan for a technicality (melacha shein tzricha legufa, shinui, mekalkel, etc.) then psik reisha d'lo nicha lei on an issur d'rabbanan would be assur. But if the issur is ikkaro midrabbanan like electricity then psik reisha d'lo nicha lei would be mutar.<br>
