What factors Influence Flow Rate?

Flow rates are influenced by several factors. These include:
The model of shower installed.
The water system in the property.
Pipework installation - size and type of pipework, number of 90 degree bends.
Other outlets being used at the same time as the shower.
Debris in the supply pipes or filters.
Please note: due to these factors, any maximum flow rates quoted are approximate only and are based on an optimal shower installation.
