The first thing you need to do is check your water pressure. They you need to determine if you have an open or closed system. A closed system is usually created by a PRV, water softener, or in some cases a check valve in the meter. 
Most likely, for North Kansas City you will only need a thermal expansion tank if you have a PRV.
