What size connection do I need?
This will depend on the type of development and the amount of water you require.For most domestic properties a standard 25mm or 32mm connection will be sufficient .
For larger commercial properties you may require a bigger supply - this will be based on the fittings e.g. toilets, basins, showers etc you are planning on installing in the property.
