New homes are built to comply with modern building regulations. Part G is entitled 'Sanitation, Hot Water Safety and Water Efficiency'.

The regulations set maximum water consumption levels for new dwellings, which affect:

  • flow rates of taps and showers
  • toilet flushes
  • bath sizes
  • dishwasher and washing machine specification

In order to meet the requirements it is often necessary to install flow restrictors to taps and showers. Even if the incoming water pressure is high, these flow restrictors can cause your shower or taps to perform differently than you might otherwise expect. However, they should reduce your water consumption and therefore save you money.

Example of a flow restrictor which may be fitted to a shower:
