Regular servicing of your Pure H2O water purification system keeps all impurities out of your drinking water.


Why we recommend an annual service for your water purification system:

  • Protect the investment you’ve made in your Pure H2O system by servicing it each year. Replacing the exhausted components every 12 months keeps your system fully optimised so you’ll enjoy the great taste and benefits of pure water day in, day out.
  • Did you know the levels of slug poison (metaldehyde) in our tap water exceed the legal limit and water utility companies cannot remove it? Your RODI drinking water system removes 100% slug poison along with all other impurities.
  • If you book a service each year your warranty is extended for a further 12 months, free of charge.
  • 2015 service tariff : Warranty service £249 inc VAT / Non warranty service  £199 inc VAT

It is not recommended customers install or carry out any repairs to their system.

    Why should I buy a PURE H2O purifier when there are others on the market?

    Our technologically advanced systems are unique; they are the most efficient in the world. They last longer than any others on the market and consistently produce pure water with the absolute minimum of water usage. To find out more about what makes our systems the best available, please click here


    Other companies talk about ‘5 stage purification processes’ – you should know that it is the membrane that removes impurities; other stages sound impressive but are not the key to purity.  Our membranes last up to 10 times longer than others on the market, meaning a saving of £1,000 on membrane replacement over a 10-year period.


    Do your purifiers remove beneficial minerals from water?

    This is a common question and we answer it in full here. Briefly, minerals in water cannot be digested, therefore minerals in water are simply impurities that have never, and will never, benefit you. We DO however get beneficial minerals from the food we eat, specifically plant-based food. Please read our interesting articles about minerals, water and food, please

    I’ve heard alkaline water is better?

    This is a common myth, and in fact quite the opposite is true. We look at this question in full on our blog; please click here to read the article


    Which purifier is best for me?

    The RODI S is the system we recommend most frequently; it removes 99.99% of impurities and has an auto-flush feature meaning absolutely no maintenance, as well as extended life of the membrane component, saving up to £1,000 over 10 years.


    Does the size of my house / amount of water I drink determine which purifier I should have?

    No, it’s about the level of convenience you require and your budget. We have 3 purifiers at different price points to suit you; the RODI S, our most advanced system, the RODI which is the same as the S, but with a manual (once a week) flush, and the RO. You can see full details about them here


    Can I drink my softened water; can I give it to my pets?

    Softened water is unlikely to cause any adverse effects on health, but UK regulations call for homes to have a hard water supply for drinking (of course hard water has its own drawbacks, which is why people ask us to install purifiers).


    Please don’t give soft water to your pets. They can drink regular tap water, or Pure H2O water from any of our purification systems.


    Can I brush my teeth with softened water?



    Should I adjust the amount of detergent & softener I use in my washing machine if I have a softener

    Yes, you can reduce these by 50% (no matter what product labels say).


    Should I still use salt in my dishwasher if I have a softener?

    No, with a softener you don’t need to use any salt whatsoever.


    What about rinse aid?

    You can continue to use rinse aid as normal.


    Is there a charge for installation?

    No. Installation by one of our trained technicians is included in the price (unless specified).


    How quickly can I have a system installed?

    Within 2 weeks from when we hear from you, but we will do this sooner if at all possible.


    Do you cover every area of the UK?

    Yes, including the Isle of Man and Channel Islands subject to additional transport charge.


    How long will installation take?

    Purifiers typically take 2 hours; we offer timed appointments within a 3-hour slot for your convenience. Softeners and Conditioners usually take a whole day.


    Do I need to do anything to prepare for installation?

    Purifiers: Please clear out and clean the cupboard where your purifier will be installed (typically under the kitchen sink); the purifiers usually take up half of a single cupboard.


    Softeners  & conditioners: We’ll visit you for a site survey before installation and will be able to advise if you need to do anything.


    Do I need a power socket?

    Yes, the purifiers and softeners use 1 power socket (just like a washing machine or dishwasher does). Conditioners do not need a power socket.


    What about water supply?

    Purifiers: We take a feed from the cold mains and run a drain to the sink. We take care of all of this; you don’t usually need any plumbing work done in anticipation of our visit.


    Softeners require access to mains water and drainage and again we take care of this.


    Can I install a system myself?

    A site survey and installation by our specially trained technicians is included in the price of our systems, and provides a full warranty. We do not recommend you install our systems yourself; we cannot provide a warranty if you do so.


    Do I need to do anything to maintain my system?

    The Pure H2O RODI S system does not require any maintenance whatsoever.


    The Pure H2O RODI and RO Purifiers just require flushing once a week. This is easy; if your system is empty (you’ve recently turned the tap on), just turn the flush valve handle, leave it for 5 minutes, then turn the valve back off. If your system is full (you haven’t turned on the tap recently), then run the tap for a moment (we suggest filling a kettle for later use), turn the tap off, and turn the flush valve handle, leave it for 5 minutes, then turn it off again.  You’ll know your system is flushing because it will make a louder noise for a few minutes.


    Softeners: top up with salt twice a year – we deliver the right kind, as you need it.


    Conditioners: none.


    Other than that, you just need to book an annual service for your purifier with one of our friendly engineers; this can be booked with our customer services team on 01483 617 000 or
