This is much weaker than the original brass and can result in mechanical failure of stressed components. The problem is more likely in potable water systems than heating or chilled water as it requires a high oxygen concentration.’</ins></div></td></tr> <tr><td class='diff-marker'>&#160;</td><td style="background: #eee; color:black; font-size: smaller;"></td><td class='diff-marker'>&#160;</td><td style="background: #eee; color:black; font-size: smaller;"></td></tr> <tr><td class='diff-marker'>&#160;</td><td style="background: #eee; color:black; font-size: smaller;"><div>--[[User:BSRIA|BSRIA]]</div></td><td class='diff-marker'>&#160;</td><td style="background: #eee; color:black; font-size: smaller;"><div>--[[User:BSRIA|BSRIA]]</div></td></tr> </table>
