supply

You're right, they should be on the supply, mainly to get the expansion tank on the suction side of the pumps. In general, pumps should push, not pull.

Pumping away

I pipe everything this way. Expansion tank/air eliminator, then circs and or zone valves, all on the supply.

Tell ur plumber buddy to SUPPLY us the beers...... In my dad's 1954 something B&G book, shown some systems have pump on the supply side... Found a old National U S boiler manuel (1963) stating pump should be on supply side... Let us know if ur buddy needs the address from us to send the beer....
