Pipes and tanks are destroyed by incompatible fluids. Of course you can't put molten iron in an iron pipe.

With this mod, you will have acid-resistant plastic pipes and (if space age is enabled) heat-resistant refractory pipes, which must be used for some particularly dangerous fluids. Other mods can define their own pipe and fluid types via the API.

If this mod is added to an existing save, it will not change the behavior of existing pipes. It only affects pipes that are built while the mod is running.

Modding API

The mod associates each fluid type with a fluid category (such as "inert" or "acid"), which represents the fluid's properties. Each pipe, underground pipe, or tank type has a set of fluid categories that it can handle without damage.

To define a fluid category: remote.call["call-plumber"].register_fluid_category{category=category_name}
To associate a fluid with a category: remote.call["call-plumber"].register_fluid{fluid=fluid_name, category=category_name} where fluid_name is the name of the fluid prototype.
To associate an entity with a category: remote.call["call-plumber"].register_entity_compatibility(entity_name, list_of_category_names) where entity_name is the name of the entity (e.g., pipe) prototype.

If an entity is not registered then the mod does not change its behavior.

The predefined rules can be disabled with the setting call-plumber-scripting-only.
