Reverse Osmosis (RO) Drinking Water

Solution

Reverse Osmosis (RO) Drinking Water

Important facts you need to know

Before you invest in a RO system:

 

All RO purifiers use 'crossflow' mechanical filtration and have a waste to purified water ratio of 3 to 1 at best. This means that at least 30 litres of water go to drain for every 10 litres of purified water produced.

RO purification is non-specific - it takes out the good elements as well as the bad. Water has many good elements eg Calcium, Magnesium, Zinc, Electrolytes to name but a few.

Humans, in nature, have never drunk pure water. Indeed pure liquid water is non-existant in nature

They take up about a quarter of the space, or more, in a standard undersink cupboard.

They need a waste connection.

Expensive compared to a water filter. Our basic Pearl-T undersink drinking water filter, which is adequate for most peoples needs, is just £69.30 delivered totally complete.

Health warning? There is a substantial and growing body of medical & expert opinion against Reverse Osmosis drinking water purification. Not only because the good elements are removed but because of the 'aggressive' and acidic nature of purified water. H2O is nature's solvent so the thinking is that it can and does leach out beneficial elements you take in with your food & drink.

Up until this year (2007) we manufactured and supplied our own brand of RO purifiers. For us, the final nail in the coffin for Reverse Osmosis was this from the website of the Drinking Water Inspectorate for England and Wales; an exact copy taken 22nd February 2007:

 

"Reverse osmosis systems
Reverse osmosis (RO) filtration systems remove virtually all dissolved solids, soften the water and produce a waste stream equivalent to 20-30% of the incoming flow. There is also a substantial reduction in pressure through the RO unit. RO may have applications within the home if the consumer is using water for specialist purposes such as photographic processing or hydroponic culture. RO treated water should not be used for potable purposes. Because of the correlation between cardiovascular disease and consumption of naturally soft water the Department of Health has advised that consumption of artificially softened water should be avoided.

 

Consumers should also be aware that installation of RO could increase water bills by up to one third because of the waste stream. The Water Fittings Regulations require that consumers give notice to their water company of the intention to install a RO system."

 

In view of all this up to date information, as a responsible water filter manufacturing company, we have withdrawn RO from our inventory completely.

 

Do we have alternatives?


Yes, lots ! With no water wasted, bad elements removed, beneficial elements retained, taking up a fraction of the space used by RO, more cost effective to buy and maintain.

 

For those of you worried about hormones (eg oestrogen), endocrine disruptors and pharmaceutical residues; all our Pearl and Oyster models will filter these out.

 

All supplied totally complete from incoming cold water 'saddle valve' connector to dispensing tap (with different tap models if required).

Doulton are the recognised world leaders of water filter cartridge technology. We incorporate the Doultontm Imperial Supercarbtm or Ultracarbtm Silver impregnated self-sterilising Ceramic Cartridges with an Activated Carbon Block core to cover just about all eventualites in the two Pearl Super & Ultra Models. If you simply want the best without further ado, then:

Q. Why do you use a helpdesk instead of just emails?

A. Using the helpdesk ticket system means that we can ensure that all the questions, requests for information, and other correspondence between us and our customers is saved for reference.

It makes it much easier for whichever person handles your message to see everything that's been said. This enables us to provide you with a much more efficient, and better service.

Q. When I send a message through this helpdesk, what happens?

A. When you submit a ticket it adds your message into a private system and then sends an email to each of use to let us know there's a new message, or reply to a message.

That prompts us to log into the system, find your message, and then answer you. You'll receive an email telling you we've answered.

That email will have a link in it that takes you to the ticket where you'll see all the messages that have been added.

Q. Why does my ticket say it's closed?

A. When we've answered a query in a ticket we tend to close the ticket, unless we've asked for more information and it should stay open.

This is so that we can see which messages we've received still need to be dealt with and keep it all manageable.

If you want to reply, all you need to to is type a response, and the ticket will automatically reopen itself. There's no need to submit a new ticket.
