Need to replace my water pump
My water pump has started leaking. It was made in 08/1990, so it's probably time. The original pump was a Shurflow 2088-403-144. This is a 3-chamber pump that shuts off at 45 PSI and does 2.8 GPM...

You can put in whatever works. I'm not sure why you're concerned about such a small power draw.
Mostly I'm concerned about increased pressure in the plumbing.
My drain valves already leak, and are not accessible to replace. At least the two under the bathroom sink are not.
They mostly leak when if they are stuck in between fully open and fully closed, but weep even when closed.
But I'm mostly curious why they would spec out a pump with different operating parameters from the original when it seems like there is a pump out there that matches the original specifications almost exactly.
Original pump:

Factory Shutoff: 45 PSI
Max Flow: 2.8 GPM
Max Current: 4.6 amps

Factory Shutoff: 55 PSI
Max Flow: 3.0 GPM
Max Current: 7.5 amps
Best match I found:
https://www.freshwatersystems.com/specifications/2088-554-144.pdf
Factory Shutoff: 45 PSI
Max Flow: 3.5 GPM
Max Current: 5.2 amps
Also the physical form factor of the best match I found matches the form factor of the original more closely.
