Choosing the Right Tap for Your Kitchen: Factors to Consider for a Perfect Fit

Choosing the Right Tap for Your Kitchen: Factors to Consider for a Perfect Fit

Choosing the right tap is an important step when it comes to upgrading your kitchen. It’s essential to invest in a tap that is both functional and durable. We have to start with the right buy. Don’t go for the cheaper ones, but choose a middle-range tap at least, and we advise you to buy a tap which is manufactured in Britain.
There are many brands on the market! To buy a suitable kitchen tap for your kitchen sink, we have to consider something about the water pressure in your home. Usually, the water pressure in the kitchen is mainly fed so you will not have any problem with the water pressure.
Before starting the installation process, it’s crucial to consider the water pressure in your home.

What about if you have low water pressure in your home?

Most kitchen taps and sinks receive water from the main water supply, which usually provides adequate water pressure. However, if you have low water pressure throughout your house, you may need to select a tap specifically designed for low-pressure systems.

Alternatively, you can explore options such as installing a booster pump to improve water flow.

This is a small job, but to make your life easier you need a few handy tools and materials to finish the work. ( kitchen tap tools) You need a:

Set of 8-piece spanners (monoblock spanner), Pipe cutter, Basin wrench, Adjustable spanner, Pump pliers, Flathead screwdriver, Backnut spanner, Loctite or PTFE tape, Plumbers mate jointing compound, Isolating valve (if needed), Bucket, Towel, New tap

Not necessary tools and materials: Masking tape Flexible hose connections, open mains pipe connections, tap joins.

Make A Plan Before You Change A Kitchen Tap

Before changing your tap, it’s important to create a plan to ensure a smooth installation process. Familiarize yourself with the manufacturer’s instructions, assess the current state of your sink and plumbing connections, consider the design and functionality of the new tap, and take into account the water pressure in your home.

By making a plan and gathering all the tools and necessary materials beforehand, you can ensure a successful and efficient tap replacement.

Switch Your Mains Water Supply OFF – Turn off the water supply

This is the first and most important thing you do. If you don’t know where to turn off the water for your tap, you STOP NOW. If you can’t close the water supply you don’t even start. There can be a complication with the installation, and even the smallest one can cause major leak damage.

Where is the stop tap?

Normally you can find the stop tap or main shut-off valve under the sink in the kitchen cupboard. If you found it just turn the head clockwise to close (anticlockwise to open). Sometimes the handle is really stiff and you need a plier to complete the stop tap.

If you can’t find the main shut-off valve on-off valve in the house then close the stop valve in the street. You can find the stop tap underneath a black plastic lid written with water on the top. You can turn off the water by turning the valve head a third clockwise direction a quarter anticlockwise.

Sometimes you are lucky and there is two isolator valve underneath the sink on the right angles with copper pipes here. These are compression fittings. You can close this one too, but we prefer to isolate the whole house because these isolation valves sometimes leak when you disturb the joints.

Double-check if the water is shut off by opening the taps and now you also can drain out the leftover water.

Disconnect The Pipes

Before proceeding to disconnect the pipes, it is essential to prepare for potential water spillage. Have a towel and a small bucket ready to catch any water that may flow out when the water pipes themselves are disconnected and the tap handle is opened. This precautionary step will help prevent water damage and make the process cleaner and more manageable. Place the towel and bucket strategically beneath the water pipe connections, to catch any water that may be released. By being prepared and proactive, you can minimize the mess and ensure a smoother transition during the tap replacement process.

You have three options to disconnect the kitchen tap:

  • If there are 15 mm compression-fit copper pipe connections, you can undo the nuts with an adjustable spanner. Also, you have to hold the old tap so it won’t twist and undo the nuts on the hot and cold sides.
  • Another option is when you have flexible pipe connectors. You can loosen the nuts with an adjustable spanner where which connects to the pipe or isolating valve. Sometimes the nuts are very tight. Unscrew the nuts and take out the flexible tap connectors.
  • The third option is to cut both 15 mm pipes and install an isolator valve. Sometimes you have to go with this option.

You might need a faucet wrench or a monoblock spanner. It all depends on which one can be used to access the nuts/ single-threaded rod easier. Sometimes the single-threaded rod and nut are rusty and the space is really tight. Now, this can be a messy job. If you can’t unscrew the tap single threaded rod from underneath, you have to cut it down. This is a really rare occasion but it can happen.

If you manage to take out the tap from the kitchen worktop, now you can clean the surface. There can be some limescale leftover. Disconnect the existing tap. Please make sure to check the hot and cold pipes. ( the existing taps have connection alignment assured)

Prepare The New Tap

Read step 1 of the installation manual. Unwrap the tap from the box, and start to put it together. There will be two flexible tap connectors (pipes). You just have to turn this into the hot and cold side which you can find underneath the tap body.

Meantime underneath the tap body screw in the supplied single-threaded rod and insert the rubber washer seal.

Now is a good time to put the plumber’s mate sealing compound underneath the tap body where it will touch with the kitchen worktop. Normally the rubber seal that the manufacturer supplied is enough for the seal, but we like to use this jointing compound for extra protection.

The last thing you want is to finish the installation and have a leak.

Install Your New Kitchen Tap – How to Fit a Kitchen Tap

You can insert the kitchen tap into the worktop. You have to hold it in one hand while with the other you will put the fixing bracket underneath the bottom tap hole. You will have to use the monoblock spanner set to tighten the nuts onto the single-threaded rod.

Believe it or not, this monoblock spanner can save you a lot of time. You can struggle 15 minutes with an adjustable spanner or you can finish the job properly within 2 minutes.

Check the tap alignments and tighten the nuts.

Connect The Pipes To The Mains Water Supply

Now you can connect the two pipe cutters and two flexible tap connector pipes to the hot mains supply and cold mains pipe connections. If you have to cut the 15 mm copper pipe just do so and install 2 new isolator valves on the pipes.

After you installed these isolator valves, you can connect the flexible pipes.

Tighten the nuts but with one hand also hold the isolation valves.


Just watch out for the flexible pipes not to twist. You can avoid this by using two pliers in one hand. With one plier you hold the isolation valve, with the other you hold the flexible pipe to avoid twisting (you have to hold both pliers with one hand). And with your other hand, you can use an adjustable wrench or spanner to tighten the nuts.

And that is it, the kitchen tap is fixed and is connected to the water and supply pipe. Now you close the isolation valve with a flat screwdriver.

Pressure Test The Tap

All you have to do now is to turn back on the hot and cold water supply. First, you check if the isolation valve that you installed is not leaking. After your success, you can check the valves you can open the isolation valve with a flat-head screwdriver by turning it anticlockwise.

Check for leaks. If it’s all fine now you are ready to test the tap.

After you finished the tap installation, open the cold water first, leave it to run for 1 minute until the air will come out and after open the hot side.

Sometimes after an installation, if you open both the hot and cold sides at the same time, you can have an airlock. This means the higher-pressure cold water can push air back to the hot side. This issue is very common in mixer taps.

And that is it, now you succeeded. Your installation is ready and hopefully, you don’t have any leaks.
