After installing a squat switch (such as the Peregrine brand), did your plumbing pass a pitot/static leak test?

I have heard gossip of the Peregrine switch having pitot/static leak issues. Is there another approved squat switch known not to leak?

This last summer I installed the Perigrine ground/air speed switch, with a small syringe applying just enough pressure to read 50 knots airspeed, reading is steady as a rock for over 20 minutes during a transponder-Ads_b check.
Good Luck,
