Cistermiser Combimate Scale Remover

Living in a hard water area, my taps, showers and boiler are plagued by bad limescale build up. If not managed limescale will continue to grow and cause longer term damage.Although this product works well at reducing the building of new limescale it's prudent to to remember that the balls are not a limescale remove and will not remove existing scale.This is a well known brand in the industry that is proven to be effective. I tend to refill my combimate about every 9-12 months on average. Given the modest price point, it works out a couple of pence a week over the life span of the balls.Great longevity and value for money.Happy to recommend

I would definitely recommend this cheap, easy to use alternative to very expensive water softeners. It gets rid of 99% of Lime Scale without leaving a nasty smell like some others do. It is the most effective Scale-removing tablets I have used. This product leaves my sink spotless and shiny.

you only know if theses work after enough time has passed without lime scale. I'm into year two and yes the scale is decreased but I can see that if you want to eliminate the problem entirely you will have to spend the money for a softner.I live in a very hard water area and it took 6 years before the boiler needed a new £250 heat exchanger thingy. I would guess that these balls will give me a couple more years but critically have the showers and taps working as best they can for longer.

Good item

Excellent with 2 seals

Refill existing product

I have replaced these crystals yearly since installation & found them great for keeping the water system clear of limescale

Good product. I've previously paid a heating engineer to install this product each year. Very easy to do yourself and save some cash. Remove the combimate cover by depressing the two red buttons at the side of the combimate. The cover then pulls off forward. This isolates the water supply and gives access to the dome containing the crystals. Place an old towel under the dome in case a small amount of water (half a cup at most) drips out. Unscrew metal ring anti clockwise.Pull dome forwards. Will be stiff but hand tight. Empty out old crystals. Replace rubber seal which is included in pack. Replace dome. Tighten metal ring. Now you can reove the cap on the top of the dome with the small red plastic spanner . Drop the crystals (silphos balls) in one by one. Replace cap. Push on front of combimate till it clicks.That's it. No need to prime anything. Check for leaks, which if the provided seal is inserted correctly there shouldn't be any.Takes 10 minutes max.
