I have a "closed" HVAC system. There is a drain line to dispose of condensed water that drips to the outside. There is also a cold water line that branches into the HVAC unit and also dead-ends at an indoor spigot. When I open the spigot, cold water flows freely.
I want to attach a hose to the spigot for regular use, but I am confused about why it also branches into the HVAC unit, and I don't want to cause any damage.
Maybe, if the main is turned off, the spigot could be used to drain the HVAC unit, even though there is already good drainage (but as far as I can tell the water main is on and has been on for years).
Any and all help in understanding this design, and if I can use the spigot for a hose hook-up, is appreciated
