Water Systems

Identifying your water system
The type of shower you choose and its performance will be influenced by your water system. For example, if you have a gravity fed system and want to install a Hangrohe shower, you might also need to consider fitting a pump to boost flow and pressure or choose one of our products that operate at 0.1bar. However, if you have a mains fed water system, you will not be able to add a pump to increase pressure.

There's a product to suit everyone, but taking time to identify your water system now can save a lot of time in the future. We recommend asking a qualified plumber to give you good advice and further guidance.

Gravity fed systems
Gravity fed systems tend to be found in older properties and have a hot and cold feed. There is normally a cold tank in the loft and a hot cylinder in the airing cupboard.

The greater the drop (called "head" of water) from the bottom of the cold water tank to the top of the showerhead, the better the shower's performance.

You are able to fit a pump to boost the flow rate and performance of a gravity fed system.

A Combination boiler is better known as a Combi. A multi-point heater is a similar type of system. Both can vary in shape and size but are usually located in the kitchen and fire up to heat the water the moment you turn on a hot tap.

You must not fit a booster pump to the this type of system.

Mains fed hot water cylinders can vary in shape and size and can be found in airing cupboards or garages. Many can be recognised by the expansion vessel on the top of the storage cylinder.

This system supplies water at high pressure and is often fitted in newer or refurbished properties.
