Water conditioners....

Hi All, Does anyone have an experience with the Permutit canister type water conditioners; the ones wot introduce a small quantity of Polyphosphate into the water feed. Do they work as claimed?
I was looking to fit one on the feed to the hot water system, and maybe the washing machine.

I've used one of these (or rather a similar product) for a relative's system.
They certainly do work, and unlike the magnetic/electronic devices do so consistently and with well known scientific principle.
However, you do need to understand what they do and what they don't. They are a water conditioner and not a softener, and as such will reduce or stop scale build up -e.g. in the water cylinder, heat exchanger in combi boiler, electric shower or element in washing machine.
They are not a water softener, and will have no impact on detergent and shampoo consumption. The only way to do that is with a proper ion exchange water softener using salt. If detergent and shampoo economy as well as scale elimination is what you want to achieve, then if you use a water softener which regenerates based on use, you can certainly cover the cost of the salt with the savings.

They do work very well. Fit it on "all" of the water supply, except the kitchen drinking tap and outside tap. Fit it at the stopcock and have a double check valve between it and the tee to drinking tap. You need to change the canister about every year. It will not remove existing scale, so treat existing scale with Viakal.
Electronic wrap around wire descalers work, but on some installations they do not. I have one and it works. Most makers give a 5 years guarantee and 1 years no quibble replacement if it doesn't work.
