Ratings and Reviews for  Cistermiser 15mm Limescale Prevention Device and Combiphos Starter Pack COM1

If you live in a hard water area you'll need Cistermiser to protect your boiler from limescale build-up.

Item has only been in a week but I’ve noticed the water has softened noticeably.

Used to replace a previous Cistermiser that was installed 16 years ago.

Bought to replace old leaking Cistermiser.

Works very well in our house all elements hardly scale at all.

Replacement for the one that came with the house. Very effective.

Early days, but all seems to be working well!

Was easy enough to install. Will discover the result after use.

Living in a hard water area this is perfect to ensure I don't need to descale everything else.
