This is a pretty cool video explains how an expansion tank function.
I shared this video with yicheng how to install an expansion tank.
We consider replacing the anode rod and this video provides very good tutorial. It seems simple, but to screw it back can be very difficult. Sear also provides detail instruction as well.
It turns out that we need to replace the heating element from this (videos) but the themorstat seems fail so we want to test the thermostat.
To replace the heating element, we follow this video. Again, nothing works easily as the video shows. In our case, we have hard time to screw the element back.
