When it's happening, (it's intermittent) I can even hear it vibrating in the radiators as well as the pump itself.
The pump is attached to a water pipe that's more than an inch in diameter, presumably it's one that circulates the hot water to the radiators. I see that it goes into the back of the oil fired boiler.
The pump is a Grundfos Selectric UPS 15-50, like this:
I'm guessing that a bearing is wearing out (or maybe dirt inside?) but should I be looking to repair or replace the pump?
Are they relatively easy to teardown and repair?
If I decide to replace the whole pump then is it a job I could do myself ? I two stop taps (no wheel attached to either though) each side of the pump so at least I won't need to drain the system, just attach a wheel/handle or use a wrench.
Anything in particular that I need to be aware of if replacing it? I note that I'll need to connect it up electrically.
It it simply a matter of take old the old and put in the new or do I need to also make sure that I use PTFE tape on the threads, etc?
I also notice that you can buy new or refurbished, not sure what I'd go for.
