Expansion Tank

[chuck172]

I'm waiting for my Amtrol Sx-160V to arrive. I've read here that it should be piped on the suction side near the circulatior pump. I have three pumps. Any problem with tee'ing it in before the pump going to the 500 gallon pressurized storage?

It should be connected to the suction side of the pump dealing with the worst pumping situation (head loss), thus ensuring that the pump is starting from zero pressure. Typically, that means the pump feeding the heating zones.
