Welcome to the Sunstar Solutions website. We are the manufacturer’s representative for the Act, Inc. D’MAND Recirculation Pump. The D’MAND Recirculation pump is a hot water recirculation pump that works on demand only.
This pump is different from the competition and here’s why: • It is the only type of pump that will not void or reduce the warranty for tankless water heaters. • It is the only type of pump that is LEED Certified and UL listed. • The pump will only come on when you tell it to.
