The expansion tank needs to be adjusted to the cold system pressure when it is completely empty of water and isolated from the system. Only way to do it.

This cross reference guide offers the best cross reference from other drain manufacturer’s products to a Josam equivalent series. You may need to add options to the Josam series to match the other manufacturer’s options. In some cases, adding options on a competitor’s model will require a different Josam series than the one selected in this chart. If you need assistance with product cross reference, please contact Josam Customer Service.

There is a major misunderstanding with the expansion tank pressure. You need to start at 12 PSI air pressure in the tank and set the boiler feed cold (ambient) temperature to 12 psi. They both need to match. [huge snip]

Thank you all for the helpful replies. It's been a hectic day. Let me answer a little and then try to take and post pics tomorrow.I bought a liquid filled gauge and attached it to the hose bib on the boiler. Surprisingly the original gauge is tracking right along with it.The expansion tank was originally 1/2 to 2/3 full of water. During my reconfiguration, I pumped it up to 20 psi. But then it only was filling the top 2 or 3 inches, so I let a little air out, bringing it down to 17 psi.When I let a little water out of the system, the pressure drops. But then it climbs right back even though I have adjusted the PRV. I need to try setting it to 12 psi tomorrow when it is at ambient.Again, thanks all, and I'll be back tomorrow.Jay
