    Ordered 10 and 5 were shipped quickly. others took a while, but Presair followed up well and customer is happy.

  2. david shelton (verified owner)

    I installed and tested the unit i purchased and it was sensing anything above 0 psi to 5 psi and alarming when zero pressure is avail. now after a couple months of service, the unit is throwing a closure alarm connection while at 5 psi. Is it possible that they are designed to throw a closure for anything OVER 5 psi?
