==Description==
==Project description==
The article describes methods of implementation of various cases of bypass ventilation in sewage installations.
The attached projects present an exemplary solutions for a sewage installation with bypass ventilation.<br/>Schemes A-D are applicable to buildings from 3 to 5 floors (less or equal to 12m in height).<br/>Schema E - for the buildings with more than 5 floors (more than 12m in height).


==Location in the program==  
==Files to download and project information==
In many cases of bypass ventilation the internal structure of stacks should be changed. This is achieved by modifying stack data: types of pipes inside, declaration of elements on the top, declaration of internal connections, etc.
===Schema A===
The type of the stack is indicated in the ''<IS_TS id=DataEditorTable/>''.<br/>[[File:Bypass ventilation location.png|900 px|left|thumb|1. <IS_TS id=typyWlaczenWPionie/>.]]<br clear="all"/>
* Direct parallel ventilation: vent stack is connected to the sewage stack at the bottom near the stack foot, and at the top to the vent pipe;
All necessary points should be specified. Some geometrical data (distances between internal connections) have default values, but these may not fit all cases and often require manual correction after observing the 3D model.
* ''<IS_TS id=LacznikiNaKazdejKondygnacji/>'' can be made or not depending on the project features.<br/>[[File:Bypass ventilation schema A.png|900 px|left|thumb|1. Schema A.]]<br clear="all"/>[https://download.instalsoft.com/public/helpsystem/EN/SUF/Sewage-installations-Bypass-ventilation/ISPROJ/Bypass_ventilation_Schema_A.isproj Bypass ventilation Schema A, isproj]</br>
===Schema B===
* Indirect parallel ventilation: vent stack is a separate one, and is connected to the branches on each floor. Horizontal ventilation pipes are to be drawn manually, correcting the elevation where necessary;
* ''<IS_TS id=pinNameZaworOdpLubNapow/>'' is used as an ''<IS_TS id=EndOfSewerageLine/>'' for both stacks (''<IS_TS id=strKanalizacjaSanitarna/>'' and ''<IS_TS id=strKanalizacjaWentylacja/>'').<br/>[[File:Bypass ventilation schema B.png|900 px|left|thumb|2. Schema B.]]<br clear="all"/>[https://download.instalsoft.com/public/helpsystem/EN/SUF/Sewage-installations-Bypass-ventilation/ISPROJ/Bypass_ventilation_Schema_B.isproj Bypass ventilation Schema B, isproj]</br>
===Schema С===
* Direct parallel ventilation: vent stack is connected to the sewage stack at the bottom near the stack foot and at the top to the vent pipe;
* ''<IS_TS id=LacznikiNaKazdejKondygnacji/>'' are made automatically;
* Connection to the vent stack from each fixture on the first floor and from each sewage branch on the floors above.<br/>[[File:Bypass ventilation schema С.png|900 px|left|thumb|3. Schema C.]]<br clear="all"/>[https://download.instalsoft.com/public/helpsystem/EN/SUF/Sewage-installations-Bypass-ventilation/ISPROJ/Bypass_ventilation_Schema_C.isproj Bypass ventilation Schema C, isproj]</br>


==Example of use==
===Schema D===
The program provides several schemes of bypass ventilation. Please note, that all changes inside the stack can be achieved only by changing stack data (no graphical edition possible). After drawing and connecting a ventilation pipe-run to a sewage pipe-run, manual correction of the elevations may be necessary. 
* ''<IS_TS id=pinNameZaworOdpLubNapow/>'' is used on the first floor for the most distant fixture;
Schemes A-D are applicable to buildings from 3 to 5 floors (less or equal to 12m in height). Schema E - for the buildings with more than 5 floors (more than 12m in height).
* ''<IS_TS id=iNameSanWentylacjaKanalizacji/>'' are connected to the sewage stack on the floors above.<br/>[[File:Bypass ventilation schema D.png |900 px|left|thumb|4. Schema D.]]<br clear="all"/>[https://download.instalsoft.com/public/helpsystem/EN/SUF/Sewage-installations-Bypass-ventilation/ISPROJ/Bypass_ventilation_Schema_D.isproj Bypass ventilation Schema D, isproj]</br>
* Schema A:
===Schema E===
** Direct parallel ventilation: vent stack is connected to the sewage stack at the bottom near the stack foot, and at the top to the vent pipe;
* In high buildings the fixtures on the lowest floors should be connected to the additional sewage pipe in the stack;
** ''<IS_TS id=LacznikiNaKazdejKondygnacji/>'' can be made or not depending on the project features.<br/>[[File:Bypass ventilation schema A.png|900 px|left|thumb|2.

* The additional sewage pipe should be connected to the sewage collector at least 2 m from the base of the stack;
* Schema B:
* ''<IS_TS id=LacznikiNaKazdejKondygnacji/>'' is declared as well;
** Indirect parallel ventilation: vent stack is a separate one, and is connected to the branches on each floor. Horizontal ventilation pipes are to be drawn manually, correcting the elevation where necessary;
* The connection of the additional stack to the main stack is made automatically by the means of a "vent loop". <br/>[[File:Bypass ventilation schema E.png |900 px|left|thumb|5.
