Venturi Shower

A venturi shower contains a special shower valve that offers high flow rates without having to use a pump or power shower.

Features of the Venturi Shower include

high rates of flow
good pressure
no electrical connections
plumbs straight in
push fit connections
economical
low maintenance

Venturi showers are a relatively cheap and easy to install, for bathrooms with gravity fed hot water systems and mains pressure cold water.

Venturi showers will not operate with high pressure hot water systems such as combination boilers or unvented systems.

How They Work

High pressure mains cold water is used to "suck" tank pressure hot water through the special venturi valve inside the unit, so that the resulting mixed water comes out at a much greater rate than could be achieved using an electric shower or ordinary shower mixer valve . The venturi shower uses no electrical connections, it simply plumbs straight into the heating system.

There must be a 300mm gap between the top of the shower head and the bottom of the supply tank (click diagram to expand).

Venturi showers will only work where there is low pressure, tank-fed hot water and high pressure, mains-fed cold water - an arrangement which is commonly found in UK homes.

The Aquadart Hydroflo was a very popular venturi shower but has been discontinued for some time. New Team currently have a venturi shower in their range called Jetstream
