Revision history [back]

Good day, all,

I have looked high and low for a durable, inexpensive low cost tap that can be used in gravity fed handwash stations, to little avail. This appears to be a major stumbling block to primitive school and home handwash setups. If you know of any, please post them here - or provide links, leads to some.

Scenario: youngsters or adults walk up, push a button or pull a lever (which is easily cleanable, or washed by the water flow) and the water sprinkles onto their hands for a short time, then turns itself off. It works typical low-pressure gravity fed system (e.g. tank raised a few meters),

It must be easy to manufacture in each developing country which restricts imports. Ideally they would be made of inexpensive materials that can be found in most cities in developing countries; or from inexpensive moulds that can be used to cast plastic etc.

Here is what I've found so far:

1. USA & Chinese valves you pull down, which shut off automatically, but they require 20-30psi, not operate at very low pressure; example: Hippo one-touch tap; video: www.hihippo.com/en/2012en/talktous_02.html

2. hy2u - plastic bag, inside decorated cloth bag, with ball valve carved from wood or other material: https://www.hy2u.net/content/technological-perspective___________.... and

3. the most promising so far, Impex 10092-2V Calf nipple 1/2" https://www.impex.nl/en/category/35/cattle_bull_nipples.html (because people who raise cattle may perhaps use the same tap for humans and cows). I am corresponding with them.

What options have you found? In what countries and regions are they available? How reliable in the field are they?
