: The difference between an upright head and a pendent head is, an upright sprinkler is designed to be installed upright in the branchline piping of a sprinkler system. The pendent is designed to be in the pendent or 6 o clock position, with the deflector facing downward. It is important that you always install sprinklers in accordance with their designed listing; you cannot install an upright sprinkler in the pendent position, for example. you can usually find this information with the data sheet supplied with the sprinkler. If in doubt, contact the sprinkler manufacturer. Sprinkler installation is regulated by National Fire Protection Association or NFPA for short, document number 13.. This standard gives the codes for proper location, selection, and installation of fire sprinklers.
A sprinkler designed to be installed in such a way that the water stream is directed downward against the deflector.
Oh, dude, the minimum distance between the ceiling and slab required to install an upright sprinkler system along with a pendent in a fire fighting system is typically around 18 inches. But hey, who's really counting, right? Just make sure there's enough room for those sprinklers to do their thing and you should be good to go. Like, safety first, man.
yes
The deflector (part shaped like a daisy) is shaped differently to give the water the correct spray pattern,
Upright heads
When the fire protection is required above false ceiling to protect cables or combustable materials.
Maximum drop of the deflector when the concealed sprinkler cover or what they call escutcheons is released, should be at least 1/4" of an inch from the horizontal height of the ceiling to spray the water during sprinkler operation in case of Fire.

To cap a sprinkler head, you can use a sprinkler head cap or plug that fits the size of the sprinkler head. Simply twist or push the cap onto the sprinkler head to cover it and stop water flow. Make sure to turn off the water supply before capping the sprinkler head.
It depends on the use of "pendent"you are refering to. In biology, "pendent"means loose or hanging in refering to a structure or organ so the antonym may be "rigid" or "erect". In law, "pendent" means "forthcoming" so the antonym may be "complete" or "past". Structurally, the "dependent" may be any object that requires a group of other structures for support, each other object being a "pendant" and taken together they form an "independant".
You do not need the sprinkler use the t pipe to drop water on the plant and using that is easier than the sprinkler since it does not work Your welcome
Sprinkler systems can use many components that control the flow of the water. A plastic piping connects the water supply to the electric valves and the sprinkler.
