4.2 Servicing
Supply fittings, excluding supply stops, shall be designed so that replacement of wearing parts can be
accomplished
a) without
removing the fitting from the supply system;
b) without
removing the piping from the body;
c) without
disturbing the finished wall; and
d) using
standard tools or manufacturer-provided tools.
Swing spouts designed to use adjustable packing in the joint between the spout and the body shall be
constructed so that the adjustments can be made without removing the spout.
4.3 Installation
A method of sealing between the fitting and the fixture to which it is fastened shall be provided.
4.4 Threaded connections
4.4.1
Pipe threads shall comply with ASME B1.20.1.

4.4.3.1
Aerators and other end point devices with standard threads shall be compatible with one of the
following thread designations:
a) 13/16-27
UNS-2A, 3/4-27 UNS-2B, 15/16-27 UNS-2A, or 55/64-27 UNS-2B; or
