Does the static pressure dropping affect the operation of anything within my plumbing system?

If the static pressure after the TankBoost unit drops below 2 Bar the pump will activate for a few seconds to repressurise the system. Typically, on mains fed systems most appliances (combi boilers, taps, electric showers etc.) require a minimum of 1 Bar ‘static’ pressure to function so the TankBoost is well within these requirements. The TankBoost operates on the same principle as our negative head shower pumps, these initially switch on by monitoring pressure rather than flow.
