Can we install your filter?

The usual answer is no, sorry, we do not come and install your filter.

This is because the great majority of our filters are designed to be very easy to install on your own.

However if it's a larger filter, like installing a whole of house type or you have special requiremments and are happy to pay someone else to fit a smaller DIY type filter then we do have a list of independent installers in most parts of the UK.

Please note that replacing / changing any filter - even a large whole of house type - is almost always very simple and can be done DIY

Please Contact Us for more information.


To Replace Your Undersink Type Cartridge


A) Turn off the water supply to the filter

B) Open the counter top filter tap – to relieve water pressure

C) Positioning a bucket or bowl underneath - to catch any water spillage - unscrew the bottom of the filter housing and remove the old cartridge. This can be discarded.

D) Wash the housing thoroughly. Rinse well.

E) Place the new cartridge into the lower housing. Make sure that both rubber “ O Ring” seals are in place at the top and bottom of the cartridge ie fitting neatly into their slots.

F) With the cartridge in place screw the housing and top back together. Screw tight.

G) Once this is done turn on the water - ie at the saddle valve - and check for leaks. If there is a leak the housing should be tightened further.

H) Run about 2 gallons of water (approximately a sink full) to flush the cartridge.

Your water is now safe to use.

The cartridge will be good for approximately 6 months. We will email you a reminder

If you are away for anything longer than a weekend always flush the cartridge through on your return - as per (H) above.
