I have access to the rest of the switch, but the part needed to screw into my pipe is missing. I'm sure someone has run across a non-operational Potter VSR-ST and is willing to sell me the union piece I am missing, rather than just throw the entire switch in the trash. I wish the manufacturer would sell parts, but they don't. I'm even willing to buy a used part, as long as it is still in good condition. I care about functionality, not looks. I appreciate any help anyone can offer.

Changing it to one with a time delay would solve the problem. But why not just disconnect it. The is no requirement in 13d for an audible alarm or monitoring.

How do you suggest I add pressure to my system?

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.

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.
