An in-line expansion tank (10) includes a sleeve (14) defining a volume (24) , a pipe (18) positioned within the sleeve, and an annular flexible bladder (2 2) disposed within the volume between the sleeve and the pipe. The pipe defines a fluid flow channel (20), and an outlet at a downstream region of the pipe in fluid communication with the fluid flow channel. The bladder and the sleeve define an outer radial chamber therebetween. The chamber is pressurized duri ng normal use and the bladder is configured to contact the pipe during operatio n at normal water pressure to minimize dead space between the bladder and the pipe. The tank includes a valve (26) for pressurizing the chamber.
