Connection to a Mains water supply.
A minimum of 1.5 bar pressure on hot and cold water is required for QETTLE Original and Signature taps. QETTLE Mini requires a minimum of 1.5 bar pressure on cold water only.
Please note if water pressure exceeds 5 bar, a pressure reducing valve must be fitted.How do I find out?
The water pressure of most properties is typically between 1.5 - 5 bar (it’s usually around 3). In a few cases, where water pressure is greater than 5, a pressure reducing valve must be fitted to reduce the pressure.
If you’re unsure what your water pressure is, knowing what type of plumbing system your home has will help.
1. High Pressure Systems usually generate enough water pressure for our taps.
2. Low Pressure Systems typically don’t generate enough pressure for the QETTLE Original to work perfectly (not an issue for the QETTLE Mini). The boiling water, filtered drinking water and your normal mains cold flow are unaffected but your hot water flow will be much slower than with a conventional kitchen tap. This needn’t be a problem (a lot of people who use boiling water taps don’t mind) but there are things we can do to improve your QETTLE’s performance. Give us a call on 01603 875464 if you want to discuss options.
If you want to measure your water pressure you’ll need to measure both hot and cold for the QETTLE Original and just the cold for the QETTLE Mini. To test your mains water pressure, you’ll need a water pressure gauge. Gauges are widely available from online retailers such as Amazon and shouldn’t cost more than £10.00.
Use an outside/garden tap to test your cold water pressure. Outside taps usually have a ¾” BSP connection – so you should be able to screw the pressure gauge straight onto the outside tap. Once the gauge is attached to the tap, turn the tap on and take the pressure reading.
To measure the pressure of your hot water, you will need to turn off the hot water supply. Disconnect the hot water hose from your existing kitchen tap, then connect the pressure gauge to the mains hot water supply. Turn the water supply back on and take a pressure reading.
A standard, 13 amp socket to plug in your QETTLE’s boiler tank.
You’ll need a double socket if you are also installing a QETTLE Chiller.Find out more
Power to the QETTLE’s boiler tank is supplied via a standard, 13 amp socket under the sink. The socket should be installed prior to your QETTLE being installed and is not included in the QETTLE installation.
You’ll need a double socket if you’re also installing a QETTLE Chiller.
The ability to shut off the water.Find out more
Water can be isolated either by isolation valves on the existing hot and cold water pipework under your kitchen sink, or by using your home’s stopcock.
An under sink waste pipe already in place.Find out more
If you have a functioning kitchen sink, you’ll already have a waste connection. QETTLE’s vent assembly attaches to your sink’s waste. Find out more about what the vent does and how it should be fitted here.
Space for your QETTLE’s boiler tank under the sink.How much space do I need?
A 4L QETTLE boiler tank and filter system can be accommodated by a 400mm wide (or larger) kitchen cupboard. If you are also installing a QETTLE Chiller, your cupboard should be a minimum width of 600mm and proper ventilation is essential.
There must be clearance of at least 80mm above the top of a boiler tank and/or chiller to ensure hoses and connections are not squashed.
Take care if you have a Belfast or butler sink.

A 35mm diameter hole (this is the UK standard tap hole size) for your QETTLE tap and 10cm clearance behind your tap and the back of your sink, windowsill, upstand or splashback.Find out more
Your QETTLE tap will need a 35mm diameter tap hole, which is the UK standard tap hole size. All QETTLE taps, apart from the QETTLE Signature Classic and Signature Mixer taps, use a progressive valve to control the normal hot/normal cold flow of water. The lever handle only moves outwards and forwards, so there is no need to worry if your tap is positioned close to the wall or splash back.
If you are ordering a QETTLE Signature Classic or Signature Mixer tap, please ensure there is 10cm clearance between the centre of the tap hole and the wall or splash back.
An alternative design of QETTLE Signature Classic, with a progressive valve is available by special order. Watch our video below to learn more.
