Jaison Water Tap
Self-closing tap
The Jaison Water Tap or Jayson Water Tap (also known as Waste Not Water Tap) is a self-closing water-saving tap invented in the early 20th century by J.P. Subramonya Iyer at Travancore, India. Jaison taps were widely adopted across India, and still are used at many railway stations operated by Indian Railways.
History
J.P. Subramonya Iyer, who invented the tap, served as an insurance officer in the erstwhile Travancore-Cochin state. The tap was meant to reduce the water wastage which occurred when road-side water taps were left open by their users. With the help of a few friends who were engineers, such as Sri Rajangam (Deputy Chief Mechanical Engineer of South Indian Railway) and S.L.Narayanan, he developed the tap.
He patented the invention, improved it further and patented the improved tap version as well. The Jaison water tap was the first of its kind to be patented.
In order to facilitate large-scale production, Subramonya Iyer set up a factory at Karamana. Due to militant trade union activism prevalent in the region, the factory had to shut shop and moved to Coimbatore.
International use
The Jayson Tap has been used in many countries such as Nepal, Sri Lanka and Bhutan particularly in rural environments.

Why this record matters
The subject matters to the general reference register because the source frames it as self-closing tap. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 3, 2026. The linked authority identifier is Q42417204. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
