In many of today’s potable hot water heating systems, back flow preventers are required by code. Since this seals off the system, an expansion tank is required or the relief valve will discharge on every heating cycle. DuraMACTM Expansion Tanks eliminate this wasteful and costly practice.

The MPIX and MPI series has all the features of the MH series, but includes a powder coated liner in the water containing area. This unique bonded surface provides positive protection against rust and corrosion and meets today’s sanitation requirements. For other conditions, please contact our Pump Department for assistance. DuraMACTM Expansion Tanks must be installed on the cold water supply side of the water heater and placed between the water heater and check valve or back flow prevention device.
