Step One: Remove the Old Sink

Turn off your water supply before you start work and remove the old sink. If you are re-using old taps, use adjustable wrenches to remove them from the old sink. Never remove the earth wire straps from the pipes under the sink. If you’re unsure, always call in a certified electrician to check the bonding.

Step Two: Line up The Sink To Tthe Wall

Line up the new sink against the wall, using a spirit level to check it is level.

Step Three: Check the Connections

If you’re lucky, you may be able to connect the water supply pipes and waste directly back to the sink trap and the taps. Use the washers and gaskets supplied to give a watertight seal around the new taps. Try to fit as many parts to the new sink as possible before fitting to the worktop or wall, so that you just have to make one connection under the sink when it’s in place.

Step Four: Connect the Pipes

Connect the overflow to the waste pipe with the parts supplied. Place the sink into the worktop or screw to the wall and double check all the pipes can be easily connected.

Step Five: Seal the Gaps

Seal around the lip of the unit with a waterproof sealant. Use two adjustable spanners to tighten the joints on the flexible tap connectors. Make sure the flexible tap connector pipes aren’t stretched or kinked.
