How do you fix a leaky ceiling fire sprinkler head?
We have exposed fire sprinkler heads in our house. We noticed that the one in our master bath is leaking with a slow drip. Do you have to get plumber for this or is this an easy fix?
They are easy in principle. first turn off the water source. 2nd drain line. I would recommend replacing the head all together so you don’t have to distinct between the valve where the glass is or the joint above. you might try to tighten, clockwise the head prior to replacement and see if it turns tighter. if it turns then maybe it just was not really tight to begin with. once new head is installed, if you have a compressor, you can use air to see if it leaks. merely put the air on it, have a gage installed between the fire system and valve. turn off air by having a valve between sprinkler system and compressor. If the same pressure holds for a day, then you will have no water leaks. if you don’t have a compressor, then you will have to fill with water, it should be ok. make sure to use proper pipe sealant. Good luck.
