Yes/No Hardness Tablets

Yes/No Hardness Tablets - Fast and effective water hardness test. Yes/No Hardness Tablets - Fast and effective water hardness test.

Availability: In stock

Many areas in the UK have a water supply that is naturally hard (water that contains high levels of calcium and magnesium). Water hardness can lead to the build-up of calcium and magnesium (limescale) in pipes, radiators, cylinders, pumps and boilers and can significantly reduce efficiency. More visible signs of limescale around the house tend to be around taps and bathroom fittings and in kettles, washing machines and dishwashers.

These hardness tablets are a fast and effective method of determining water hardness. They can be used to determine initial water hardness or used regularly to ensure the continued effectiveness of an already fitted water softener.

Each pack of Pool Chemical Products Yes/No Hardness Tablets comes with 50 easy to use tablets.
