Jeff,
Which codes are you referring to (2003, 2006, 2009, 2012)? There is no Subnote "e" & "f" to
Table 2902.1 in the 2006 IBC.
From the 2006 IBC, Section 1109.5.1 = Minimum number: "No fewer than two drinking fountains
shall be provided. One drinking fountain shall comply with the requirements for people who use a
wheelchair and one drinking fountain shall comply with the requirements for standing persons.
Exception: A single drinking fountain that complies with the requirements for people who use a
wheelchair and standing persons shall be permitted to be substituted for two separate drinking
fountains."
Your question now brings up other related questions. What are the requirements of a
Drinking Fountain for a standing person (i.e. - minimum height of the lip of the fountain,
minimum height of the drinking spout?). Is a "Hi-Low" actually required, or does a
single drinking fountain meet the requirements of both the ADA & non-ADA users?
Also, is there somewhere that identifies the use of "bubblers"?
