When I first installed my TST system with the CAP style sensors, I started having leaks from the flexing of the valve stems. I replaced all of them with metal stems. like 1 inch, purchased a dozen from a local auto parts store in 2 packs. Cost about $2.50 each. I had all 8 of them changed out at my local tire store. No more intermittent leaks.
To wait or not would be your decision. BTW, they have lasted thru several sets of tires so it's not a regular expense. Just make sure to tell the tire store to leave them on and just change the schrader valve insert.
