All QETTLE taps have a standard hole size of 35mm diameter.
If you’re replacing an existing kitchen tap, it’s wise to check the space between the back of your tap and the splashback, windowsill or wall. The QETTLE tap’s lever handle, which is used for flows of normal hot and cold water, needs 10cm to ensure it can be moved all the way back. If you are short on space, don’t worry – you can still have a QETTLE. Just tell us your QETTLE will need to be fitted with a progressive valve. This is a special valve that allows the hot/cold lever to work in a slightly different way, without being obstructed by a wall, windowsill or splashback.

You can install a QETTLE tap onto a variety of different work surfaces. Quartz, granite, marble and other solid surfaces should always be templated by a work surface professional. Bear in mind these work surfaces often come with an ‘underlay’ of fibreboard, which is relatively soft, and, as the tap is tightened up, can move over time. This can cause the tap to wobble, so it is best to remove the soft underlay and ensure the tap is clamped against the hard surface.

QETTLE boiling water taps have been designed to be simple and straightforward to install – whether you’re a professional installer or a happy DIY-er. Our step by step installation video will guide you through every aspect of planning and carrying out a QETTLE installation. It’s also worth viewing our pre-installation videos that tackle how much space your QETTLE’s boiler tank and filter system is likely to take up under your kitchen sink, water pressure and power.
Here’s our step by step installation video.
QETTLE taps need a minimum of 1.5 bar pressure on both hot and cold water feeds. In the UK, it would be unusual for mains cold water pressure to be lower than 1.5 bar, and generally, if your home has a combi boiler or mains-fed hot water system (e.g., a Megaflo), you are likely to have good hot water pressure, too.
Take care if you have a gravity-fed plumbing system (where hot water is stored, typically in a loft space), as these systems can have lower pressure and will often need a helping hand in the form of a small pump.
If you are in doubt about your home’s water pressure, ask a qualified installer to measure it for you.
Our video about water pressure is also helpful.
If water pressure is higher than 5 bar, you will need to fit a PRV (pressure reducing valve). The valve is easy to fit, is fitted inline with your tap’s pipework and can be purchased from us.
Watch our video about why water pressure matters.
Yes, you can. Our blender valve is a clever accessory that draws a small amount of boiling water from your QETTLE’s boiler tank and mixes it with normal cold water. The blended water becomes your flow of ‘normal’ hot water. It is the perfect solution if you don’t have a supply of mains hot water to your sink – common in office kitchens, workshops, studios etc. You can also opt for a blender valve as a solution if you have very low hot water pressure. Bear in mind that if you are using a blender valve, upgrading your QETTLE’s boiler tank size is sensible – i.e., opt for a 7L, rather than a 4L.

QETTLE taps and systems installed above ground floor – i.e., in an apartment, above a shop etc – should always have a floodsafe device fitted. This is a simple accessory that includes a water block. Should there be a surge in water pressure (common in apartment and commercial buildings) the floodsafe device will be triggered and the water supply will shut off.
Currently, the floodsafe device is not available to purchase online. Please tell us if you would like to add a floodsafe device to your order.
Watch our video to understand more about how the floodsafe device works.
Not as much as you might think! A QETTLE 4L boiler tank can be easily accommodated by a 450mm wide kitchen cupboard. Remember that whatever size boiler tank you choose, there must be at least 80mm above the boiler tank. This ensures hoses and connections are not squashed.
It can help to think of your QETTLE’s boiler tank as a big kettle. But, unlike a kettle, which has a spout for steam to escape from, the boiler tank is a sealed unit. So, the vent is there to allow steam to be released and for water droplets to run away into the waste.
Watch our video to understand more about the vent’s function.
Yes, of course. Ideally, we suggest that a hard (unsoftened) flow of water is fed to the boiling/filtered side of your QETTLE tap, and that softened water is fed to your tap’s normal hot/cold flows. Softened water is subjective, but please note that it is not recommended that babies or very young children drink softened water. The QETTLE filter system will not remove additional sodium from softened water.

Installing the QETTLE Chiller is very easy. You can fit a chiller at the same time as you install your QETTLE or at a later date, providing you allow adequate space in your cupboard and make provision for ventilation. The QETTLE Chiller is around the same size as the 4L QETTLE boiler tank; a standard 600mm wide cupboard will accommodate a 4L boiler tank and a chiller. Always ensure there is ‘breathing space’ between the boiler tank and the chiller and that additional ventilation is available in the form of holes drilled into the rear of the cupboard or a grille in the ‘kickspace’.

A QETTLE tap and system has two, simple maintenance requirements – its filter cartridge will require replacing twice a year, and its boiler tank will need an annual deep clean. Both are easy, routine jobs that you can do yourself and that are inexpensive. We’ll send you a friendly reminder to let you know when your filter cartridge needs replacing (also watch out for the LED on the base of your tap to flash red) and when it’s time to deep clean your tap’s tank. Filter cartridges cost under £30.00 and tank cleaner costs under £10.00.
You should replace your QETTLE’s filter cartridge twice a year.
Yes. The QETTLE tank should be deep cleaned annually. This is an easy, inexpensive procedure that you can do yourself.
It’s really easy – a 10 minute job! You won’t need a plumber or specialist maintenance engineer. You simply turn off the water to your QETTLE’s boiler tank and filter system using the shut-off valve, unscrew the lower section of the filter cartridge’s housing, remove the old filter cartridge, pop the new cartridge in and reassemble.
