Household Water Filters. advice needed please
Hi All.
Once again I'd like to tap into the wealth of knowedge on this site please.
The problem.
I live in a very hard water area so I have to replace shower heads every 3 months, shower units every 3 years,
de-scale the kettle every 2 weeks, but worst of all, scum on my tea. 
The posible solution.
I can't afford the 5 to 6 hundred pounds for a full blown salts system so I wondered what the cartridge filters are like.
Anyone use them or can offer advice?
I'm thinking of fitting then as in the pic below. (particulate filter, polyphosphate de-scaler and carbon drinking water filter)
These are made by Culligan and sold by Screwfix but I'm open to sugestions. I think I could fit these for £140 ish.
Any advice will be much appreciated.
Cheers
Paul G

They are really only good for say one tap for drinking water.
The volume of water going through one of those for an entire house will quickly use it up.
The salt system is your best option

We probably have similar water at out house.
I just ordered a water softner from Plumbworld which will solve the
problem all around the house.
At our last house I installed a Brita water filter tap (charchoal filter I think) which helped with the nastry tasting tea with scum on top
problem.

Dont forget you need to protect the feed serving the hot water side otherwise you will build up limescale inside your cylinder and boiler, it is the
hot water that gets effected most.
Also you need to protect your white goods - washing machine, dishwashers etc

What you mean those magnetic descalers don't do anything?

I think the biggest issue with trying to control the scale in an entire house is making sure you can still get a good flow rate... no use only being
able to draw off a few litres an hour if you want to shower/washingmachine etc

I have no idea how good these are, if they work or might as well be Snake Oil but there only on offer until tomorrow!
Maplin Descaler
The Plumbing company I work for has just fitted something similar to a Commercial Business at the request of the Catering contractors for the
dishwashers so they may be some use.

Yeh they're magic  You wonder why anyone bothers with those expensive water softeners  I think it's a bit of emporer's new
clothes in plumbing form..... All this cobblers about electromagnetic (whether permanent or electric) fields effecting water softness is quite
amusing. Still, boiler companies won't repair under warranty unless some kind of protection is fitted and seeing as there is no evidence these
don't work they pay out when a boiler protected by it gets furred up....

Thanks for all the replies chaps.
Looks like I might go for just the drinking water tap then.
At least I'll be able to have a decent cuppa while I replace the shower.
As a matter of interest, what's the running cost of a salt system?
Cheers

p.s. Fancy the BBQ meet David?

careful with the salt systems, they can cause corrosion of your copper pipework as the protective patina on the inside of the pipework relies on there
being calcium carbonate in the water. A 50% mix of softened and hard water would stop excessive furring and eliminate the rsik of corrosion, plus
might save you some money in salt!
