Building and Developing

What size connection do I need?

Connection size

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.

You can use our flow calculator determine if you need a standard connection or something a bit bigger.
