A tamper-proof plumbing arrangement for a water meter in an establishment for preventing the owner of the establishment from reversing or bypassing the water meter. The water meter has the internal shut-off valve for the establishment as an integral part of the meter such that the water meter cannot be removed while the shut off valve is closed. The water meter has a main housing which houses both the water meter and the shut off valve, and has a small, unbreakable window at the top of the meter to allow the meter to be read. The small Plexiglass window prevents the gauge reading from being altered by the customer.
