PSC 185.77(3)(d)
(d)
When a complaint or dispute occurs. When a utility receives a complaint under s.
PSC 185.42 or is notified about a dispute under s.
PSC 185.39 involving a meter-related issue, the utility shall keep the meter, in “as tested" condition, at a designated location on the utility's premises for at least one full billing period plus four weeks after the complaint or dispute and any appeal of that dispute is resolved so that the meter is available should testing be requested. If the meter was tested during the complaint or dispute process, and it tested as accurate, the utility may choose to keep the tested meter installed at the customer's premises for the designated time period rather than storing it at the utility's premises.

PSC 185.795 Electrical safety. Jumpering meter settings. Under certain abnormal conditions, a dangerous voltage may appear across the meter setting when the water line is electrically opened as by removal of the meter. Before a water meter is removed (or the interior piping leading to the service otherwise opened), an appropriate electrical jumper shall be connected across the meter setting or proposed opening in the piping to maintain electrical continuity. If the water supply piping is used as a ground for the building's electrical service, the electrical jumper shall not be removed until a meter is again set or the piping closed. The utility shall inform the customer that the electrical jumper shall not be removed until a meter is again set or the piping closed.

PSC 185.82(1)(1)
Under conditions of normal heavy system demand the residual pressure at the meter outlet shall not be less than 20 p.s.i.g. For typical residential customers, normal conditions of use shall mean a flow rate of not less than 12 gallons per minute. This standard assumes that the customer's portion of the service lateral is of normal, adequate design, and in good condition. This standard shall ordinarily require that the distribution main pressure at the corporation stop connection be at least 35 p.s.i.g. The utility is to establish minimum specifications for the service lateral to assure that excessive pressure drop does not occur in the lateral because of its length or for other cause.
PSC 185.82(2)
(2) The maximum pressure at the meter shall not exceed 125 p.s.i.g. The maximum pressure at the meter shall not exceed 100 p.s.i.g. for new systems and, to the extent practical, major additions to existing systems.
PSC 185.82(3)
(3) Each utility shall have at least one permanently installed pressure gauge on its system and shall have access to indicating and recording pressure gauges to check pressure levels.
PSC 185.82(4)
(4) Each utility shall make such pressure tests or surveys as to assure that the pressure limitations of subs.
(1) and
(2) are being met.
