Question Circular malfunctioning, how can I tell?

Hello how can I tell that the circular in my boiler system is working correctly?
I think it is a “Tacco 007-4F” brand I am not sure about the spelling.
Thank you.

Circulator not working?

Taco 007 circulators are some of the most reliable on the market but will fail once in a while. I usually use a screwdriver with the blade firmly against the circulator & the handle pressed against my ear. You should be able to hear motor running.

Question Circular malfunctiooning, how can I tell?

I did try that before I posted the thread. It is a subtle noise.
Is that it?
The rooms in the second floor warm quickly; can I obtain that from the gravity only?
The technician who purged the system wasn’t sure about the good functioning of the circular because after the purge, through the drain valves, the system was reversed (the zone supply line was cold and the zone return line was extremely hot). I had to shut the system for three or more hours and then restart it to reverse it to normal.
My house is a two story house and I have three zones controlled by a single thermostat.
Thank you,

Noise/Gravity

What you should hear is a slight "whirring" noise.
Hot water will migrate as high as the second floor if there is nothing there to stop it.
Are there any valves to shut off the second floor?

Valve

You may be able to throttle back the second floor if it heats too quickly. I don't understand how the direction of flow could have been reversed. The circulator only pumps one way & the flow control valve should prevent backward flow as well as gravity flow.

Exclamation Supply side cold/ return hot after purge

Just after the purge the supply side was cold and the return side was very hot. So I had to shut down the boiler till both sides cooled down.
Now it is working like it is supposed to.

Question Circular Problem

Do you know what is the normal running temperature of the circular? Mine is always burning hot.
I shut the boiler and I have the circular pumping cold water and in no time its temperature, the circular, increased dramatically is that normal?
Thank you.

Circulator temp

If you are feeling the motor, it should get warm but not extremely hot. The body (cast iron part which connects to the pipes) of the circulator will get very hot.
