Why don't water boards in hard water areas filter the water for you? It would save their own pipes getting scaled up too.

I took my Biology exam last Friday. I was asked to name two things commonly found in cells. Apparently "Blacks" and "Scousers" were not the correct answers.

They may want the pipes (or the ones to your house) to scale up if the
area still has a lot of lead. It stops the lead leaching into the water.

I would thought this is for two reasons: cost and the fact that a small
amount of the salts which cause limescale is actually thought to be
beneficial to the human body.

And it's not filtration, which the removal of solid particles from a liquid
by a fine mesh (metal, paper, ceramic). In the case of hard water, the salts
are dissolved in the water and gradually deposit themselves onto the pipes
in your house. You'd need a chemical reaction in the treatment plant to
convert the salts to something insoluble that would precipitate out - *that*
precipitate could be separated by filtration.

So what do "filters" for preventing limescale buildup do in your house? Make sure it stays dissolved?

It is also expensive and only really matters for some things like making
tea - too much calcium and you get a layer of brown scum on top. The
right hardness matters for coffee too but only affects the taste.

Some of them do nothing at all. The magnetic snake oil variety.

The real water softening filters swap calcium ions for sodium and have
to be replaced or recharged from time to time. It is a waste softening
water unless it is for drinking or some other critical usage that
requires soft water. Hard water doesn't corrode pipes and may even seal
minor pinhole leaks - which is a benefit for the water company.

But if you get continuous deposition in the pipes, after some amount of
time no water flows.

Except in insanely hard water regions it requires evaporation and
exactly the right pH for calcium carbonate to plate out at any speed.
These conditions are not normally met in a pipe unless there is a leak.

Heating it in a kettle or boiler is the most common source od problems
with hard water since that does make it come out of solution quickly.

I recall some drain pipes in a former dye chemical plant that were
hugely entertaining when removed after the plant was closed. I believe
some clocks and other ornaments were made from polished sections of it.
Heaven knows what noxious ancient aniline dyes were in there.

They are not filters but ion exchange resin beds that exchange the
calcium in the water for sodium. You must regenerate the resin by
adding salt to flush out calcium to sewer.

Everyone should know but when you hear that maybe 20% of a population is
functionally illiterate, i.e. cannot read beyond road signs or newspaper
headline, it makes one think that technical illiteracy is even higher.

Might also have mentioned reverse osmosis which even less probably
understand and is a filtration of sorts and more expensive process.

How much does it cost to do this, compared to your water bill?

Einstein married his cousin, Elsa Lowenthal, after his first marriage failed in 1919.
At the time he stated that he was attracted to Elsa "because she was so well endowed".
He postulated that if you are attracted to women with large breasts, the attraction is even stronger if there is a DNA connection.
This came to be known as.... Einstein's Theory of "Relative Titty."

Depends where you live. I don't know about the US, but in the UK only the south half has hard water.
