Why might I need a recirculation pump installed with my new water heater?

Answer

Re-circulation systems without a re-circulation pump are designed to function based on the gravity or thermal characteristics of hot water. New water heaters have federally mandated Heat Trap Nipples that prevent the gravity or thermal expansion characteristics from moving water through the recirculating lines as they had previously. A professional solution to correct this issue is to install an appropriate pump; the technician can discuss all options with you on site.
