Should you soften the water in Manchester?

A verdict and running-cost estimate based on M2's 80 ppm reading, for a typical 4-person household.

Softener optional

Water is soft to moderate, so limescale and soap costs are low and a softener rarely pays back.

Water is already soft, so there is little detergent saving from softening.

Appliance impact at 80 ppm: negligible: appliances reach full expected life. Sized for a 4-person home; regenerates roughly every 33 days (estimate). Figures are conservative estimates and vary with household size and usage.

FAQ

Common questions about M2

What is the water hardness in M2 Manchester?
The water in M2 Manchester has a hardness level of 80 ppm (parts per million) calcium carbonate, classified as slightly hard. This is 127 ppm below the UK national average of 207 ppm.
Which water company supplies M2?
M2 Manchester is supplied by United Utilities. United Utilities serves the North West region.
Is the water in M2 safe to drink?
Yes. Slightly Hard water at 80 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 M2?
At 80 ppm, the water in M2 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 80 ppm water hardness mean?
80 ppm means there are 80 parts per million of calcium carbonate dissolved in the water. This is equivalent to 5.6 Clark degrees, 4.5 German degrees, or 8 French degrees. Water above 180 ppm is generally considered hard.
What size water softener do I need in M2?
For a typical 4-person home at 80 ppm, a 24,000 grain softener is a sensible size. It would regenerate roughly every 33.5 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 M2?
At 80 ppm, expect to use about 16 kg of salt a year, costing roughly £5–£8/year. Water is soft to moderate, so limescale and soap costs are low and a softener rarely pays back.
