Compression Tank

Where would be the best place to mount the compression tank with the current piping configuration. 2 zones. Would it be acceptable to mount the tank on one return even though there are 2 zones? Relief valve opening. Replaced compression tank in current upside down position due to customer not wanting to reconfigure piping arrangement.

you would like the tank connection on the inlet of the circs. But with two circs pumping into the boiler on the return, that is not an easy fix.

While not ideal it will work as shown

Same with the tank position nipple up is preferred, manufactures show nipple down or horizontal as options
