isolation valve on pressure switch
Posted: Tue Jan 08, 2019 3:23
Hi there, I am new to this so excuse me if i don't have the accurate lingo/terms.
On a recent installation of a residential sprinkler system (pumps from a storage tank) there is an isolation valve before the pressure switch.
If this valve were inadvertently closed, I believe the system would not detect the pressure drop, no pump start or flow switch activated, thus no alarm not to mention the location burning down.
Is this a code violation (Ontario) or just not best practice?
As the system has supervisory on the input/output valves to the pump, it did not make sense that a valve would be allowed in this position.

I was going to remove the handle as a precaution.
Your thoughts please.
