Hi all,
I am going to have 3 different cold water supplies coming into my new build (mains(kitchen tap only), softened mains(utility, washing machine, electric shower) and softened pressurised mains(all other taps & showers)).
I also want to filter the mains water at the kitchen tap (i.e. have mains, filtered and hot at the kitchen sink) and I'm not too sure how much I should filter it.

Will a carbon filter be good enough or should I have UV or reverse osmosis thrown in there also?

Have got a good price for the units and would like to buy soon but just not 100% sure which unit to go for. Help!!??

Thanks in advance.
 
Re: Filtered Water

Get the water tested & they will tell you what is in it or what needs to come out
 
Re: Filtered Water

I would not recommed RO for the drinking water. This fully demineralises the water so if you are drinking it you are not getting the useful minerals that are added/naturally occuring in the water. In severe cases it is suspected of leeching the body of minerals.
 
Re: Filtered Water

Be careful of using softened water. If the pH of the water is too low this can lead to corrosion of domestic hot/cold copper services (pinholes) in your dwelling and also damage seatings in brass taps, ballvalves etc.

Is there a reason you need feel there is something that wrong with the supply ?
 
Re: Filtered Water

I know that the water in the area is full of lime - hence the reason for the softener system.(do not want my new plumbing system to get full of limescale)

In some households in the area they will not drink the water without it been filtered but I kinda agree with Yeager that I shouldn't be taking everything out of the water.

I'm leaning towards a carbon filter with maybe a UV light source to kill all the nasties (house is in the Galway region that with hit with the Cryptosporidinm last year)

Thanks for your input so far - more welcome.
 
Is the your water a county council supply or is it a group scheme? If its a group scheme does it have its own source and treatment or does it simply distribute the coco water?

If you are concerned about the quality of your drinking water then you should have it tested in an independent reputable laboratory. Do not have any truck with door to door or cold calling sales guys offering to test your water on the spot.

Get your water tested for Bacteria, General Water Chemistry (Hadness, pH etc.) and a range of metals such as Iron, Manganese, Lead, Arsenic etc. This should not cost more than a about €100.

You should show the results to a number of reputable water treatment contractors and ask them to suggest appropriate treatment how much it would cost.
 
Temporary hard water is the water type that will affect your plumbing system with the build up of limescale. This limescale or 'furring' will build up on hot water heating elements, namely: Electric showers, Electric Immersion elements, Electric Kettles and some pipework on direct hot water systems(pipes connected between Agas and hot water cylinders.)
This water should not affect your central heating system.
Ajapale is correct. Get your water tested by a specialised water treatment company and this will guide you into fitting an appropriate water treatment unit and subsequent plumbing system.
