Is there any other way to tell if the expansion tank is bad besides knocking on it?

That’s pretty much the only way.Zman said:Much better! Remove the tank and check the precharge pressure using the schreader valve.
Same people who knock on expansion tanks must’ve learned it from knocking on oil tanks..
