nothing but trouble since. I don't have overly high (city) water
pressure; never had trouble before with anything. The house was built
in 1989. Why shouldn't I just take it out, and that way I don't have
to install an expansion tank? Any ideas, Joe?


Then the city would probably stick a backflow preventer in at your
meter and you'd be right back where you started needing an expansion
tank. Just put one in and avoid the hastle.
