Common questions about CH61

What is the water hardness in CH61 Wirral?
The water in CH61 Wirral has a hardness level of 108 ppm (parts per million) calcium carbonate, classified as slightly hard. This is 99 ppm below the UK national average of 207 ppm.
Which water company supplies CH61?
CH61 Wirral is supplied by United Utilities. United Utilities serves the North West region.
Is the water in CH61 safe to drink?
Yes. Slightly Hard water at 108 ppm is safe to drink. Water hardness affects taste and can cause limescale, but it is not a health risk. In fact, hard water contains beneficial minerals like calcium and magnesium.
How can I reduce water hardness in CH61?
At 108 ppm, the water in CH61 is slightly hard and unlikely to cause significant issues. A jug filter can improve taste, but a water softener is generally not necessary.
What does 108 ppm water hardness mean?
108 ppm means there are 108 parts per million of calcium carbonate dissolved in the water. This is equivalent to 7.6 Clark degrees, 6.1 German degrees, or 10.8 French degrees. Water above 180 ppm is generally considered hard.
What size water softener do I need in CH61?
For a typical 4-person home at 108 ppm, a 24,000 grain softener is a sensible size. It would regenerate roughly every 24.8 days. Larger households or higher daily use need a bigger unit. These figures are conservative estimates.
How much does it cost to run a water softener in CH61?
At 108 ppm, expect to use about 22 kg of salt a year, costing roughly £6–£11/year. Water is soft to moderate, so limescale and soap costs are low and a softener rarely pays back.
