Before you undertake any plumbing make sure you have everything you need to finish the job. The old outlet had no aerator and was really the wrong size for the trough. So when we turn the tap on we wasted a significant amount of water.

The new outlet has a built in aerator so the flow will be reduced and we will save lots of water. It’s worth checking every tap in the house and where possible use aerators or pressure reduction washers to reduce the flow rate. Apart from saving water you will also save lots of money.
