Decolourized Sprinkler Heads

Dear All,

 

During the site visit, I noticed that some of the sprinkler heads are decolourized, i.e. the red bulbs (68C) become transparent however the bulb is still filled with the liquid.

 

Is there anybody who knows what is the main reason for this case? Besides, should we replace the sprinkler head because of this decolourization or not?

 

Many thanks in advance.

 

Regards,

Alican
