rapid pressure change will cause the bust of polymer window.  you  
need a new detector.  you can add UPS in your pump system and alarm -  
so you have time to power down correctly (assume you are most  
experience is glitch of power supply, the UPS will do wonder... the  
alarm will allow you sufficient time to power down properly assume  
you have 24/7 monitoring...otherwise, get a big UPS.  if you have  
newer system, ask  your service guy if it can be programmed to power  
down properly in the event  of lost power - you still need UPS to  
execute the program).
my 1.4 cents.
