This is a common issue . If you use globe 1 inch drop concealed head then you have 1 inch of adjustment if your heads are too high . You will have to either cut thedrywall to access piping to adjust the head or remove the head and install what we call a cheater . Usually a 1/2 or 3/4 inch extension which will be added to the head to lower it.Dont use the brass ones , if you can use the listed 1/2 male BY 1/2 female metal . The brass ones arent listed and can crack .
I have some concealed sprinkler heads that extend about 1 inch below the ceiling drywall. How easy it is to adjust these to sit just above the ceiling drywall? Is there a regulation on this for Texas?
Not sure about regulations in Texas but typically all the regulation are based on NFPA codes and also the manufacturers instructions . Without knowing the model number of the sprinkler , the piping height in relation to ceiling height , the type of piping you are describing I wouldn’t be able to say exactly . Sounds like a renovation happened and the ceiling was raised . It is a lot easier to extend than to raise up the heads . If you have a drywall ceiling then a hole needs to be cut to enable the fitter to work above the ceiling .If ceiling tiles are used then it would be easier . Just need close the sprinkler valve , drain the system and remove and re install the heads to the proper height . Not recommended for a DIY’er .
It is also possible if you have access to the piping to raise the hangers holding the piping up. You may need to cut the rods by 1 inch to accommodate this .
I had no idea the escutcheons screwed in like that, I assumed they were just plastic caps 🤔
They are metal , mostly tin i believe .
Hello, can the cup be adjusted (lowered)? I have one that is a little too high above the drywall and can’t get the cover to screw back on.

Or just swap the head with a globe 1inch drop head .
