1 The N-Series internal pump controller is not suitable for domestic ring main applications as it does not allow the system to turn off. This means the ring main continually operates, which can cause high energy use and cost, and can be a noise nuisance, especially at night, when people are sleeping. We do however have a plumbing configuration solution if a domestic ring main is required, click here for more information.
