Customer Care Annual Reminder

Cartridges in your water filter work by absorbing chemicals from the water. Over time the media in your cartridge will "saturate" and will no longer be able to remove any further contaminants. These cartridges will also develop a build up of bacteria on the surface over a long period of time if not replaced.

Therefore it is very important to replace cartridges every 12 months and this will ensure your filter will give optimal performance & run as new, providing crystal clear, healthy water.

Our Customer Care team will send out a timely 12 month reminder that the removable cartridges are due for replacement.

Cartridges can be bought at the showroom, mailed directly to you or an annual service arranged. Please visit us at our showroom or contact our sales or service team.

Customer Care Annual Service

For a welcome service call to have your filters replaced for you, simply contact us to arrange a day & time to suit, and our friendly plumber will come to your home.

Replacing cartridges regularly will ensure your filter will give optimal performance & run as new, providing crystal clear, healthy water.


Maintenance Agreements

An easy, cost saving way to organize your annual cartridge replacement service (or 6 monthly for companies).With a maintenance agreement we can lock in the annual service charge which covers the cost of replacement cartridges and labour for 3 years so you have no price rises over that period.

A great cost saving to you and no money is required up front. Our Customer Care team will contact you when the service is due, simply book in the service and pay the agreed annual cartridge replacement service fee when it is done.
