How to fit kitchen taps

Updated February 21, 2017

Before buying a new set of kitchen taps, use the old set for a template of measurements. Measure the length of the spout and ensure your new taps will reach the sink. Measure the distance between the hot and cold taps if you are planning on replacing them with a mixer tap. Most kitchen sinks are universal in size but some taps vary in width between the attachments ends. Ensure your new taps fit the holes in the sink before attempting to replace them.

Seat the new tap through the sink holes. Let the taps sit on the plastic or rubber bedding washers. Surround the hole with silicone sealing compound tape if washers are not supplied.

Tighten the back nut by hand from underneath the sink to clamp the tap in place.

Move the spout to the correct position and tighten the back nut gently with the tap wrench.

Screw the water supply pipes to the ends of the tap underneath the sink. Use the adjustable wrench to tighten the nuts.

Turn on the water supply slowly and test the taps for leaks. Look underneath the sink for leaks as well as on the top.


Turn off the water supply before removing the old taps.


Do not over-tighten nuts on the taps.

Turn off the water supply immediately if the new taps leak after fitting.
