Lime descaler

[Dave Hurley]

Hi,

hoping someone can help. A customer has asked me to fit a lime inhibitor to the cold supply to the house. Hard water area. Problem is I cannot access any pipe work as its under the floor and under the kitchen units. Not enough pipe under boiler to fit one either. Is there a simple alternative to this?

thanks in advance

Without access to the mains supply you can't fit one. There are some magnetic systems available that do not require electricity and could maybe be attached to the mains outside the property if you can expose the pipe outside. I don't know how effective these are though.

If the rising main comes in under kitchen unit and behind cupboard just cut a big hole out the back to find it, then cover up with thin bit of ply or similar. I've fitted a few electrolytic ones to combi system and customers have been delighted with the results. I think they now do more compact 'shorter' versions. Alternatively just modify the cold feed pipework of boiler to form a loop out and back again.

A lot of people claim electrolytic ones are useless, it may be that the one area of hard water I work in isn't particularly hard so they are effective. With serious hard water they may not work as well.

People actually pay money to just have these fitted? We only fit them with combis because I'm sure someone got a backhander and its In the requirements.
