Low Head Pressure And Low Suction Pressure . Maintenance Study Time (Discussion) Wastewater 101 TXV failure can also be caused by a rub out on the bulb tube and an external equalizer without a core depressor installed on a port that has a Schrader core in place. A liquid restriction would result high superheat (warm suction line)
