Two comments about the water here in Ealing.
This has to be, by far, the hardest water
I have ever come into contact that is used on a regular basis. It is so hard, that scaling forms in water heaters so easily, and in electric percolators, and even in clean tea cups. I just have never seen its equal anywhere.
The second thing is the water pressure.
It is by far greater than I have ever experienced in any household. I love that part of it.
