I assume attaching a water hose to my test valve wouldn't help, as the
pressure from inside and outside would be the same. How do you suggest I
add pressure to my system?

I've heard of contractors pumping up sprinkler systems a few lbs over
domestic supply, rather than leaving the sprinkler at supply
pressure, so there is no subsequent flow alarm after running an
Inspectors test.
For example, our City water pressure trends up in the very late hours,
then down as daytime usage increases. This is about a five to eight
pound change, sometimes it's enough to cause systems with failed check
valves and short flow detection cycles, to alarm.

Check valve failure, so that the sprinkler leg is no longer isolated?

Subject: Seeking false water flow alarm suggestions
I drained all the water from my pipes when I installed a new water
filter/softener system in my home. After installing the new
system, which replaced some 3/4" pipe with 1" pipe in my home
water system, I have been getting false alarms from my Potter
Electric Signal Co VS-SP flow sensor. I flushed my sprinkler
system using the drain and the test valve, yet I believe some air
pockets may still remain in my two areas of coffered ceilings,
where the sprinklers sit 1 foot above the rest of the system.
Potter recommends replacing the VS-SP with a VSR-ST. I'd prefer
not spending the money to replace the sensor, but I'd like to hear
from the professionals before I make that decision. I'm thinking
there may be other solutions, especially since I never had any
false alarms during the previous 20+ years. Possibly I could
attach saddle valves between each of the two sprinklers in the two
coffered ceilings and bleed the air out. Unfortunately, I've never
had any long-term luck with saddle valves, as they have all become
inoperative over time. I've attached a photo of my water system in
case that might be helpful. Feel free to ask any questions or
offer any solutions. Thank you.
