section v - service line

Sleeves, furnished by the Customer, shall be installed in accordance with Company requirements, to protect the service line from mechanical injury or corrosion, such as where the service line passes through the building wall, through an areaway or through any unexcavated area under a structure up to the inside service stop valve. At the end of the sleeves, the space between the service line and the sleeve shall be sealed by the Customer in accordance with Company requirements. The wall shall be sealed by the Customer around wall sleeves to prevent water from entering the building at the sleeve.

Customer installed steam piping shall be properly pitched towards low points in the system with steam traps to maintain drainage of condensate. Steam traps upstream of the inside service valve and Company meters shall be furnished and maintained by the Company, and installed by the Customer in accordance with Company requirements.

Backfill around buried service line shall consist of clean earth, and shall be free of cinders, large rocks, vegetable matter, building material debris and rubbish or other foreign matter.

Pressure Drop
The Company recommends that the Customer design his/her piping so that the pressure drop from the point of service termination to the meter does not exceed 2 psig for the Customer's maximum demand at an assumed pressure of 125 psig.

When required by the Customer for the adequate sizing of his/her utilization equipment, the Company will furnish specific information pertaining to the pressure drop of its meters.

The Company requires the Customer to install equipment that will operate satisfactorily at the minimum pressure, as well as at the maximum pressure, which may be encountered. Particular attention should be given to the choice of devices where performance is sensitive to supply pressure such as ejectors for steam turbine condensers. The Customer should inform the Company when devices installed require pressure in the range of 100 psig, or above.
