The alternative term "hosepipe" is a chiefly British, South African, and southern US usage; "hose" or "garden hose" is the predominant term in other English-speaking areas. The term "[[Hose (tubing)|hose]]" is also used for other types of flexible, water-carrying tubes such as
== Description ==
Line 21 ⟶ 22:
As implied by the name, garden hoses are commonly used to transport water for gardening, lawn care, and other landscaping purposes. They are also used for outdoor cleaning of items such as vehicles, equipment, building exteriors, and animals. NSF-approved hoses may be used for connecting drinkable water to [[recreational vehicles]] and trailers.
Whenever a flexible hose is connected to a drinkable water supply, the spigot or tap should be fitted with an approved [[backflow prevention device]], to prevent contaminated water from being [[siphon]]ed back, in the event of a pressure drop. Many water suppliers require this, and [[plumbing code]] may legally require permanently installed backflow preventers
== Porous or perforated soaker hoses==
Special hoses designed to leak throughout their length are sometimes used to gently distribute water on a lawn or garden. These hoses have either many small holes drilled or punched in them, or are made of a porous material, such as [[sintered]] rubber particles. These "soaker hoses"<ref>Dave's Garden. [https://davesgarden.com/guides/terms/go/829/#b Definition of soaker hose.] {{Webarchive|url=https://web.archive.org/web/20210513225900/https://davesgarden.com/guides/terms/go/829/#b |date=2021-05-13 }}</ref> are a simple, low-cost, substitute for a [[drip irrigation]] system.

Garden hoses connect using a [[Gender of connectors and fasteners|male/female]] thread connection. The technical term for this arrangement is a "hose [[plumbing fittings#Union|union]]". [[Tap (valve)|Spigots]] or sillcocks have male hose connectors only, and the mating end of a hose has a captive nut which fits the threads there.
Line 42 ⟶ 43:
In other countries, a [[British Standard Pipe]] (BSP) thread is used, which is {{convert|3/4|in|mm}} and 14 TPI (male part outside diameter is {{convert|26.441|mm|in|2|abbr=on|disp=or}}). The GHT and BSP standards are not compatible, and attempting to connect a GHT hose to a BSP fitting, or vice versa, will damage the threads.
The connector threads are not tapered, and do not seal against leaks. Instead, a pliable rubber or plastic gasket (often ambiguously called a "garden hose washer") seals the connection against leakage. A variant of this gasket also incorporates a fine-meshed metal or plastic screen to filter out small particles of dirt that may be present in the flowing stream of water. The purpose of this filter is to intercept debris which could otherwise clog the small openings used to disperse a spray of water from various garden sprayers and sprinklers.
Various adaptors made of metal or plastic are available to interconnect GHT, BSP, [[National pipe thread|NPT]], [[hose barb]], and quick connect fittings.▼

== Quick connectors ==
In the 1980s, the use of quick-connector systems became increasingly popular. These are fittings that attach to the hose and or screw into common hose connectors and equipment, allowing hoses and accessories to be easily connected together using a snap-fit type system. The first plastic connector was invented in the UK by [[Hozelock]] in 1959,<ref>{{Cite web|url=https://www.hozelock.com/about-us/|title = About Us | Our History, Values and Innovations Hozelock Ltd|date = 10 March 2019}}</ref> and the style has now become a [[de facto standard]] throughout Europe and the wider world, compatible with and imitated by many other manufacturers. A differently-designed [[hermaphroditic connector|hermaphroditic]] quick-connect hose fitting made by GEKA has the advantage of interconnecting without distinction between "male" and "female" connectors,
Some connectors also incorporate an "autostop" feature. This is an internal valve which is shut off by water pressure, and it is opened only by connecting a fitting or appliance; thus, disconnecting a hose fitted with this adaptor will automatically stop the flow of water. This eases connecting and changing appliances without the need to shut off the water first.
