John Dirks Jr Posted July 10, 2022 Report Share Posted July 10, 2022 At the Post Office building where I also work I sometimes have to go up on the roof and reset the HVAC unit. Next to the unit is a yard hydrant. Is there a code compliance that insists this gets installed and what is the intended purpose? Link to comment Share on other sites More sharing options...
Bill Kibbel Posted July 10, 2022 Report Share Posted July 10, 2022 I see them occasionally. They're made specifically for commercial roof installation. Idon't think there's a requirement, unless maybe something local. It's handy to be able to clean the economizer screens and coils without having to leave the roof (and for techs to cool off fixing the AC in 100°). 1 Link to comment Share on other sites More sharing options...
Marc Posted July 10, 2022 Report Share Posted July 10, 2022 Never seen one before but boy, ohh boy, I'd sure love to have one on commercial roofs to help clean the coils on roof top units. What Bill said. 1 Link to comment Share on other sites More sharing options...

"and signage is code required for nonpotable" I really can't think of a reason that I would assume non-potable water would be conveyed to this hydrant.
