Pressure Gauge

Connection to a mains water supply, with both the hot and the cold water having a pressure between 1.5 Bar and 5 Bar for a QETTLE Original, or a cold water supply between 1.5 and 5 Bar for a QETTLE Mini.

How do I find out?arrow

Testing your water pressure

All QETTLE taps need a cold water supply of between 1.5 - 5 bar. For most properties, water pressure 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.

High Pressure Systems (Combi boiler, pumped)

High pressure systems usually generate enough water pressure for our taps.


Low Pressure Systems (Gravity Fed)

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.


Measuring Your Water Pressure

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 plug socket to plug in your boiler tank.

Power Source

This is supplied via a plug socket which needs to be positioned under the sink prior to the installation.

 

If you are installing a chiller alongside your boiler you will need an additional plug socket.

 

Currently QETTLE installers do not install additional plug sockets hence any additional plug sockets that are required should be installed before your tap installation.

Stop Cock

The ability to shut off the water.

Isolate Water Supply

Water can either be isolated by independent isolation valves on both existing hot and cold feeds already positioned under the sink or alternatively the mains water isolation valve supplying the property.

Waste Connection

An under sink waste pipe already in place.

Waste Connection

If you have a functioning tap, you probably already have this.

Space for your Boiler

Room for your boiler under the sink.

How much space do I need?arrow

Undersink requirements

If you're installing the QETTLE boiler, the minimum width of your kitchen cabinet needs to be 400mm.

If you're installing a boiler and a chiller the minimum width of your kitchen cabinet will need to be 600mm.

Preparing your work surface

Your QETTLE tap will need a 35mm diameter hole, which is a standard size tap hole.

Please note that if you are purchasing a QETTLE Original 4 in 1, there should ideally be 100mm clearance between the tap hole and the splashback. This is to ensure the tap’s lever handle for normal hot and cold water can be moved freely. If this clearance is not available, don’t worry, we will be able to help – but please contact our QETTLE customer team on 01603 875464 or support@qettle.com
