My gas hot water tank has begun leaking, so I started looking into replacing it and found out I have to put on an expansion tank. What do these do? The instructions say only qualified people are allowed to install it. Can a homeowner install his own expansion tank? The instructions do not look too complicated, are there any tricks I should know? Can 3/4 inch copper line really hold up a 2 gallon tank? Or should I try and strap the tank to the wall? The instructions say I need to use a pressure guage. Do I leave the guage in the line or do I take it out after I get a pressure reading?
In Washington state is it a code requirement to strap a hot water tank to the wall for earthquake purposes?
