CARE OF INJECTORS IN WINTER.
During severe frosty weather, an injector can be kept in order much easier than a pump; but it needs constant watching and intelligent supervision.
To keep an injector clear of danger from frost, it should be fitted up so that all the pipes can be thoroughly drained, by frost-cocks put in for that purpose. Bends in the pipes, where water could stand, should be avoided as far as possible; and, where they can not be avoided, the lowest point should contain a frost-cock.
To run an injector successfully, thoughtful care is requisite on the part of the engineer; and, where this is given, the injector will prove itself a very economical boiler-feeder.
