Inlets and shanks may be designed to mate with other common connections.
Note: Longer shank lengths are sometimes necessary on account of fitting orientations and countertop thickness or
materials.
4.4.8
Alternative end-threaded connections for flexible hoses and flexible components shall comply with the
performance requirements of this Standard.
4.4.9
Showerheads for installation on standard shower arms shall be capable of being connected to a 1/2 NPT
male thread.
4.5 Connections other than threaded connections
4.5.1
The lengths and diameters of solder-joint sockets shall be as specified in ASME B16.18 or ASME B16.22
for connections to copper tubes. This requirement shall not apply to factory-assembled parts.
4.5.2
Connections achieved by push-fit fittings, intended for use under continuous pressure, shall comply with
ASSE 1061.
4.5.3
Alternative end connections for flexible hoses and flexible components shall comply with the
performance requirements of this Standard.
4.5.4
Fittings with proprietary connections for aerators or other end point devices may be used.
4.6 Accessible designs
Operating controls intended for use in accessible designs shall
a) be automatically controlled; or
b) meet the following requirements:
i) be operable with one hand;
ii) not require tight grasping, pinching, or twisting of the wrist; and
iii) require an operating force not greater than that specified in Clause 5.5.2.
4.7 Backflow prevention
Fittings shall be designed to protect the potable water supply from contamination due to backflow by a
means that meets the applicable requirements of Clause 5.9.
Diverting and anti-siphoning devices incorporated into a fitting shall be removable for cleaning, repair,
and replacement.
