I have a hot water baseboard heating system. I will need a new circulation pump in the future. The current one is 36 years old. It is an inline, water cooled Fostoria (Dyna Pump) Model 470A. I would like to replace it with an identical pump, but the company does not manufacture it anymore. Maybe I could just get this one rebuilt? What are my options. I would an inline, rubber mounted, 115 volt, 2.4 amp pump.What can you recommend for me?
