Description

a) This is one in a pair of circa 1890 nickel-plated brass water service pipes. Each one has an auxiliary tube with a turned finial at its top. The water service is controlled with a disc-shaped valve knob. b) Each service pipe is fitted with a thin metal escutcheon for dressing the area where it exits the floor.

Narrative

These water service pipes were designed to provide water to a sink. They have secondary  reservoir tubes topped with finials incorporated within them. Filled with air, the purpose of these secondary tubes is to mitigate the effect of sudden changes in water pressure that result from turning off the water outlet into the sink. In certain situations, this can cause a banging sound commonly known as "water-hammer". The sophisticated design and fine craftsmanship of the valve knobs and reservoir tube finials mark these as rare examples of the finest American domestic plumbing available during the late nineteenth century.

History of Use

Unknown. These water service pipes were purchased by The Castle Society from a dealer in 2010.
