Large Pipes can be used to transmit water from the Water Pump Station.
Water Pressure Edit
Large Pipes can transmit water up to 761 tiles from a Water Pump Station, however water pressure is reduced long before these 761 tiles. Water pressure is not affected by secondary pipes that branch off the main pipe, or by the
number of objects requiring a water utility connection. Water pressure will be affected if a Boiler is placed in the path of the large pipe, so instead should be connected to the main pipe by a secondary branching large pipe. to avoid reducing water pressure in the main pipe. Low water pressure in the large pipe limits the range of small pipes that are connected to it. Water direction will always flow away from the main pipe.
Perimeter Walls Edit
Pipes can not be built through a Perimeter Wall (or Water), and building a Perimeter Wall over any existing pipe will remove it. When large pipes are build over small pipes, they will automatically replace the small ones. Otherwise building small pipes over large ones is not possible without dismantling them first.
Cautions and Considerations Edit
Large Pipes offer a large boost in tunnel digging speed. Tunnelling prisoners will dig towards these pipes when attempting to escape. Prisoners always start their tunnels under the toilet in their cell, and so it is important to use small pipes within cells and to connect to toilets as small pipes do not provide as great of a boost to tunnelling speed as large pipes do.
As of Alpha 36, sometimes large pipes burst (Random Event) and spill water everywhere. it is advised to quickly rebuild, block or turn off the water supply because it will continue to spread.
- Ideally, Large Pipes should be used as the main transport method for water to reach most areas of your prison, from the Water Pump Station to local distribution points. Small Pipes then carry water locally such as within rooms, to items requiring individual water connections like Toilets, Sinks and Showers.
- Placing Pipe Valves strategically throughout the prison can help to manage water leaks by allowing you to manually turn off water flow in the case of an emergency.
- Never build Large Pipes right to the edge of the map as prisoners are able to use them to escape.
