That is not correct neither for 22mm nor 28mm: According to EN806-3 the loading unit for DN20 Sink should be 8 loading units.</p> <p></p> <p>Please advise!</p> <p></p> <p><img src="/resized-image/__size/320x240/__key/communityserver-discussions-components-files/275871/pastedimage1554130287297v1.png" alt=" " /></p><div style="clear:both;"></div>https://communities.bentley.com/thread/513982?ContentTypeID=1Fri, 29 Mar 2019 17:01:15 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:36b17392-59cb-40eb-81d3-00622f16d894Stephen Brown<p>I would recommend the latest one available but to Update 5 at least.</p><div style="clear:both;"></div>https://communities.bentley.com/thread/513970?ContentTypeID=1Fri, 29 Mar 2019 15:52:07 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:80e676b9-a66d-40d3-8459-e29b29603296Pejman Kianbakhsh<p>which version V26?</p><div style="clear:both;"></div>https://communities.bentley.com/thread/513962?ContentTypeID=1Fri, 29 Mar 2019 15:25:48 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:67964413-d752-4119-8684-df33f7d299f5Pejman Kianbakhsh<p>I have V8i, do I have to update to V26?</p><div style="clear:both;"></div>https://communities.bentley.com/thread/513961?ContentTypeID=1Fri, 29 Mar 2019 15:20:27 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:5842536d-f9a3-4e1f-9664-8d252e9d73f1Stephen Brown<p><a href="/products/building/performance/w/building_performance__wiki/15526/pipe-sizing---pipe-sizing-standards">EN-806 changes</a>&nbsp;were introduced on V26.

From the Help file:<br /><span style="font-family:&#39;Arial&#39;,&#39;sans-serif&#39;;font-size:10pt;" lang="EN-GB"></span></p> <p style="padding-left:30px;"><span style="font-family:&#39;Arial&#39;,&#39;sans-serif&#39;;font-size:10pt;" lang="EN-GB">Outlets can be added at any position. For HWS and CWS, an outlet type is selected, which will then determine the flow rate using either <i>BS EN 806-3:2006</i> or <i>BS 6700:1997</i> loading units.<span style="font-family:&#39;Arial&#39;,&#39;sans-serif&#39;;font-size:10pt;" lang="EN-GB"><span style="font-family:&#39;Arial&#39;,&#39;sans-serif&#39;;font-size:10pt;" lang="EN-GB"></span></span></span></p> <p><span style="font-family:&#39;Arial&#39;,&#39;sans-serif&#39;;font-size:10pt;" lang="EN-GB">Regards<span style="font-family:&#39;Arial&#39;,&#39;sans-serif&#39;;font-size:10pt;" lang="EN-GB"><span style="font-family:&#39;Arial&#39;,&#39;sans-serif&#39;;font-size:10pt;" lang="EN-GB">Steve</span></span></span></p><div style="clear:both;"></div>
