How do you suggest rebuilding this check valve?

My guess is the flow switch is doing exactly what it is supposed to
do. Replacing it would give the same result as the working flow switch
already there.
The check valve would, if working, allow water at a higher pressure
into the sprinkler system leg only once and then it would check
shut. Then as the domestic side of the system has routine pressure
fluctuations, for example when domestic is used for a hose or toilet
flush, the sprinkler leg is isolated from the variability of the
domestic. No flow, so then there's no alarm.

the home system, not the other way around, but I'm open to exploring
any options. Any suggestions on how to check and repair this? I'm not
sure if the picture was attached, as I can't see it here, so I'll give
a link to it: https://1drv.ms/i/s!AnhFeJX0YorirQUGGBIOXAy4RUu2 The
check valve is just below the flow sensor. It probably would be more
cost effective to replace the flow sensor than the check valve due to
limited space and accessibility for changing the check valve (soldered
copper with no unions). I would have no problem draining the system,
opening up the check valve and repairing it, if it is repairable. What
do you suggest?

[email protected] 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 saddl e
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.
