    Faucet restrictors

    Do kitchen and bathroom faucets in most countries have built-in restrictors?

    In the USA, most modern faucets have "restrictors" to limit the flow rate. Sometimes these are in the aerator of the faucet, but sometimes they are built into the valves. The outward visual appearance of the spout of a faucet for sale in the USA cannot be used to judge how quickly water will flow through it.

    I suppose a faucet could be designed to limit the flow rate without having only one part of it designated to be a restrictor. One feature of having a designated restrictor is that ( in the USA) people find ways to remove it.

    In the UK, you can buy and fit them separately.

    And I'm one of those people.

    Most modern faucets or taps as we call them, use polished ceramic discs with tapered holes so that the action of the handle is progressive towards maximum flow. The actual maximum flow is of course restricted by all the piping and the water pressure and if restriction is required the best place is before the faucet in the form of a small hole or a pressure regulator. The type which screw onto the final nozzle is more to pacify the form of the flow. Being small parallel passageways they are easily blocked with debris or calcium and so then they do restrict the flow and should be taken off and cleaned.

    When we realize that patterns don't exist in the universe, they are a template that we hold to the universe to make sense of it, it all makes a lot more sense.

    Yup, that's the kind we've got.
