Out of stock pump and its cold!

[Jacob Hellenberg]

Looking for some help with my Rheem Prestige 9.9 Combi Boiler - 199000 BTU

The circulation pump went out and I need a new one. It's under warranty but Rheem said they are out with no ETA from the manufacturer. I found from what I thought is the most compatible and I can swap the pump housing.

Can you help? I don't know what the numbers stand for, Watts Amps, clearly a three speed? Per the manual IT MUST REMAIN ON HIGH at all times. Here is a picture of both pumps. See any issues? I see max mpa is higher and some others. The guy here was very nice and he took it apart and said it looked the same.

Grundflo doesn't have a published phone number for tech support. Old pump amp draw max is .3 new pump is 1. Flanges the same size and end to end? Or call a Grundfos online company they may be able to help. They could contact them. If it's under warranty is the install contractor helping?
