Frequently asked questions

  1. What is the difference between JMV-D and JMV-V?

    JMV-D starts on a pressure switch — the pumps cut in and out with tank pressure. JMV-V uses a variable-speed drive that trims rotation continuously to hold constant pressure.

  2. Does the JMV set include the pressure tank?

    No. The tank is sold separately and sized to peak flow. See Pressure Tanks.
