We have a hot water recirculation system in our new house that is working just fine. But we have been having some HVAC issues and a fellow who came by to give us an estimate on a new heat pump pointed to our hot water recirculation pump (Grundfos UPS 15 58FC) and told us that it was a code violation to use a cast iron pump in the domestic hot water system.
Is that true? Beyond the code issue, is there any risk from it? If so, what is the risk? If it's just premature pump failure, I can easily wait for it to die. If it's going to cause a problem with the hot water heater or the water itself, I'll have to replace it. And in that case, what is my best bet for a replacement pump?
Thanks for any help.
