Circulator pump starting to fail.

Sweet_Lew Member Posts: 116
Good Evening All,

Tonight I started to hear a weird noise eminating from the radiators. I went down to the basement and heard the noise coming from the heating system (Hot water boiler). It was the circulator pump making a slight grinding noise. How concerned should I be in replacing it? I'm trying to hold out just 2-3 weeks more until the nights here in Chicagoland get a wee warmer and I can turn off the system until next fall.

The pump is a Taco 007-F5, so I'm sure the cartridge is going so I could swap that out, maybe upgrade to a better pump (I've read Taco, Grundfos, and B&G are the more popular makers).  Anyone recommend a different pump? Here's my system details:

Boiler: Bryant Legacy BW-2

Pump: Taco 007-F5

Aquastat: Honeywell L8148E

System is in the basement. I have 4 large rads on the main floor and 4 smaller rads upstairs. Total heating area: 1500 square feet.

Thanks for reading.
