</blockquote><div><br>I immediately checked our rural water analysis to find we essentially have no copper in our system, or a negligible amount. We have a cousin who recently returned from Europe with legionnaire's disease which, with other complications, nearly killed her, so I'm not quite an complacent about the possibilities as I was earlier. Our DHW is also our floor heating system. It gets flushed during the summer with a switch of the water flow but I am aware of potential problems nonetheless.<br>
<br>So curious what the above measures mean.<br><br>thanks, Sacie<br></div><div> <br></div></div>
