Hydrotherm 145B inlet plumbing question

neald Member Posts: 1
I am trying to keep an old hydrotherm 145b going. The pipe below the recirculating pump as well as the element are corroded. The pump itself has been replaced. I know when we replace the second part of the inlet pump itself the terminal ends are so corroded they will most likely fail. Does anyone have an idea where I can source the pipe below the inlet pump, which leads into the boiler. I apologize in advance for my ignorance in terms. I am in NJ- if anyone has a good heating / plumbing tech that is willing to not just install new I would love a rec.

    If you can get the two bolts out from the boiler (pipe below the circulator). The boiler has an 1.25" (maybe 1.5") IPS female thread if I remember correctly. You can screw a nipple into the boiler and reconnect the piping.
