SQ-5-3082 Multiple Hose Station Product Alert

by JRSBlogWriterJune 20, 2011

This multiple hose station was required at a designated area for washing automobiles  in an exclusive apartment complex as a convenience to the residents. The objective was to provide multiple stations where several hoses could be attached simultaneously.  The station consisted of four cold water only hydrants,  one hot water hydrant and one twin-temp hydrant. These were segregated into four sections with each having a door that locks with a cylinder key. Each door opens a full 180° to the bottom. The hydrants were furnished with permanently attached wheel handles. The hydrants must have anti-backflow and anti-siphon  features and be non-freeze with self draining casings. Figure number 5519 hydrants were furnished for the hot and cold hydrants. These hydrants are quarter-turn  off/on with a vacuum breaker and a dual check valve conforming to ASSE 1019B and 1052. The door keys are controlled and issued to a resident upon request. The hot water hydrant is a nice feature for extra tough projects such as engines and tire wells.

This design was based upon a specific design by the owner and architect. This design can be reconfigured to accommodate  specific requirements.

PAINTING OF CAST IRON PRODUCTS:

Rust is the process where oxygen combines with iron to form metallic oxide which combines with moisture to  form rust. The majority of the Smith cast iron products are regularly furnished coated with our “Duco Yellow” paint finish. The painting of cast iron products is strictly cosmetic. The paint is applied to the cast iron to provide temporary

protection against  oxidation. It is anticipated and expected the surface coating will eventually wear away under normal use and the newly exposed surfaces will then develop  surface rust. Smith’s Duco Coated cast iron products are normally used in outside and/or in unfinished areas. Therefore, the discoloration caused by surface oxidation is usually not objectionable for products used in these areas.

Remember, the exposure of a cast iron surface does not affect the longevity, durability or performance of the drainage product in the same way it may affect other metals. It is normal for exposed cast iron surfaces to develop surface oxidation. This oxidation does  not penetrate the inner core of the cast iron wall but is usually confined to the outer surfaces.

Therefore, cast iron plumbing & drainage products do not necessarily require special coatings to prevent rust. As a result, cast iron products for plumbing applications are still superior overall to most other plumbing materials used in the same manner.

Cast iron has proven to be durable and the earliest recorded use of cast iron pipe was about 1562 in Langensalza, Germany where it was used as a water supply line to a fountain. There is still cast iron water pipe in use today in Versailles, France supplying their famous fountains that was installed in 1664.

One manufacturer of cast iron construction and drainage products does not provide the cosmetic paint coating. They state it is their policy to provide their cast iron products unpainted since it is a  cosmetic feature only.
