Trevi Shower Glossary

Thermostatic Mixer Shower

To maintain a constant temperature without having to continuously adjust the hot and cold water inlets,thermostatic shower valves are the only option.All Trevi thermostatic mixer showers* utilise a temperature sensitive wax cartridge which maintains the water temperature to within +/- 1 degree and
ensures that the temperature and pressure is automatically controlled, preventing cold water shock or hot water scalding.

Manual Mixer Shower

Single lever control with hot and cold inlet and mixed water outlet. Manual mixer showers do not compensate for variations in water temperature and pressure.

Venturi Mixer Shower

High pressure mains cold water is used to “pull through”tank pressure water through the special venturi valve inside the shower control,so the resulting mixed water comes out at a much greater rate than could be achieved using an electric shower or ordinary shower mixer valve. Gives excellent showering performance in conditions that are often deemed unsuitable for conventional thermostatic showers e.g.guest rooms,en-suites,attic bathrooms etc.Ideal alternative for electric shower.

Shower Totem/Panel

All encompassing, simple to install shower panels which incorporate a thermostatic mixer,diverter,mist jets,fixed water overhead and flexible handset for the ultimate showering experience. Suitable for use with pumped or high pressure water systems.

Ceramic Disc Cartridge

The Ceramic Disc Cartridge was developed by Ideal Standard and is the modern way to control water flow.There are no washers to wear and drip.A robust housing contains ceramic discs which control the flow of water through the fitting.Trevi valves which contain a ceramic disc cartridge are drip free
and impervious to lime deposits.

In-Line Valve

The ceramic disc technology integrated in the base of our Moonshadow slide rail,allows simultaneous use of the fixed overhead and handset.

Built-in shower valve

The shower valve body and water pipes are fitted (or chased) into the wall with the control faceplate and handles mounted onto the wall surface.i.e there is no visible pipework.

Exposed Shower Valve

This refers to a shower installation where the valve is installed on top of the finished wall surface (e.g.tiles).

Diverter

A diverter can be fitted to multiple water outlet systems to direct the flow of water between the outlet sources e.g. between handset and body jets.

Flow Control

Like a diverter,a flow control can be fitted to multiple water outlet systems to control the flow of water between the outlet sources but does not redirect the water like a diverter.

Body Jet

Directional jets that spray water and can be added to any Trevi valve on a high pressure or pumped gravity system to enhance your home showering experience.

Water Pressure

Pressure is the force that pushes through pipes.Water pressure determines the flow of water from the shower valve to the showerhead.If pressure is not sufficient then the flow can reduce to a trickle,the addition of a pump is recommended in cases of very low water pressure.

Minimum Pressure

This is the amount of water pressure required so that the shower fitting you have chosen performs adequately,the water pressure within your home depends on the plumbing system that you have installed.As a guide low pressure gravity fed systems have less than 1.0 bar pressure,high pressure
systems such as combination boilers tend to operate at greater than 1.0 bar.

Maximum Pressure

The maximum pressure stated for your chosen shower fitting is its safe operating pressure. If this pressure is exceeded then all guarantees on your Trevi shower fitting are void as this may damage the fitting.
