Usually, bathroom basins have an installation manual included in its package that you can refer to. But in this handy step-by-step guide, we show you how to quickly change an old basin tap to a new one, in five easy steps.
1. Turn Your Water OFF
First, you have to make sure that your water supply for both cold and hot taps from the mains supply is turned off. Then, make sure app your taps in the house (both hot and cold) are left open to drain any excess water.
Clear out everything you can from under the sink, including any shelves. This will give you more room to work and use your tools more easily. Once ready, add a bucket or tray below the tap to catch any drips.
2. Remove Your Old Tap
Get under the basin - you can spread an old towel across the floor or the bottom of your under-sink cabinet to catch any spills. Start unscrewing the nut that locks your basin to the old tap. If your existing tap was fitted using compression fittings, you might need two adjustable wrenches to undo the nuts. Once you have removed this, your old tap can now be pulled out.
3. Install Your New Tap
Connect the threaded post to your tap, then feed into the basin hole, so your tap sits on top of your basin, with the thread poking out below. Again, there may be a washer included or needed to make sure the tap sits snugly. Screw the nut tightly onto the threaded post, your tap is now gripped onto your basin.

Balancing water pressure
The water supply should have a reasonably balanced pressure from a common source (e.g. hot and cold supplies both from the same storage or both from a supply pipe). Where the fitting is supplied from unbalanced supplies (e.g. hot and cold supplies from separate sources) Water Regulations or Byelaws in your area may require an ‘approved’ non-return valve or single check valve to be fitted to both the hot and the cold pipes that are connected to the mixer tap.
Where this is the case, simply fit the valves below the flexible tap connectors with the arrow on the valve pointing upwards. Once fitted, this will ensure that cold water is not pushed back through the hot water pipe when both taps are on, stopping the hot water temperature from cooling too quickly.
Once your tap is gripped onto your basin, the hot and cold pipes should feed directly from your wall to your new pipes. Don't forget to check everything to make sure there are no leaky or loose connections.
4. Connect Your Plumbing
Screw the flexible connectors into your tap. After that, connect them to the copper domestic pipes, with a compression fitting in between (this will keep the pressure between the two pipes regulated and safe).
5. Switch Your Water Supply Back On
Now you can turn the water supply on from the mains. If your new tap is set to ‘closed’ when the air rushes through, it could potentially damage the tap. We recommend all taps be set to ‘open’ for a little while after turning the water supply on. Remember the other taps in your house may still be open, so remember to switch them off once water comes through again.
