Circulator noise when hot?

I agree with @hot_rod

You have a ball valve at the boiler in the MU water. You could put the tee between the ball valve and the boiler. Put the EX tank and a pressure gauge there.

If you have (in addition to the valve we see) another valve upstream of the valve we see that only serves the boiler cut the tees in between the two valves.

Make sure you install the ex tank with the nipple pointed up and support the tank or make sure where you cut the tee in you can support the tee that feeds the tank. A drain where the tanks connects is noce to have

Thank you @hot_rod and @EBEBRATT-Ed .

Is this correct? I added a tee with a pressure guage.

I have a steel beam right above the junction where the EX tank would hang. Seeing that this re-pipe woutl be copper and not have the tensile strength

, maybe a short steel or bronze nipple with a clevis hanger of some sort to support the EX. Or am I totally off here! Thank you!

Yes that will be fine. You could put another hanger on the city water supply to the expansion tank tee. You don't really need it for support, but it might be easier to hang it. One hanger is plenty though
