If you don't know the answers to those two questions ... don't be shocked, you're in the majority. However, knowing the answers can make all the difference when ordering replacement fire sprinklers.
5 Helpful Fire Sprinkler Replacement Tips
Tip 1: A qualified professional should replace fire sprinklers or in any other way modify a fire sprinkler system. If you do not know a trusted sprinkler contractor, contact us by email or phone at (888) 361-6662. We'll point you in the right direction.
Tip 2: A fire sprinkler's size describes the inner orifice diameter - either half inch (1/2"), three-quarter inch (3/4"), or in some very rare cases one inch (1"). If you measure the outside diameter of a half inch (1/2") sprinkler's threads it will equal close to three-quarter inch. The outside diameter of a three-quarter inch (3/4") sprinkler is almost one inch.
When ordering replacements, if the outside diameter of the your sprinkler's thread is (3/4") three quarter inch you should request a (1/2") half inch sprinkler.

On a side note, in our experience nine times out of ten you need a (1/2") half-inch sprinkler.
Tip 3: Try always to match the sprinkler's response type to the one you're replacing. Replace quick response fire sprinklers with quick response fire sprinklers. Replace standard response fire sprinklers with standard response fire sprinklers unless, in some approved cases, it is recommended to replace with quick response fire sprinklers. Always, equal or better.
There are two ways to tell a sprinkler's response type. You can either find the letters SR (for standard response) or QR (for quick response) stamped on the body of the sprinkler, usually on the deflector (top of an upright, bottom of a pendent).
An alternative is to look at the thickness of the bulb. A 5 mm bulb is standard response while the smaller 3 mm is it's peppy quick response cousin.

Tip 4: Spare fire sprinkler heads and a wrench should be stored in an impact resistant sprinkler head cabinet (available here) and remain accessible at all times in a facility with a fire sprinkler system installed. State regulations often apply in this matter. Check with your local fire department.
