My own hot water tank is in the roofspace and it gets a feed from the

However the cold water tank in my roofspace is much older and had a

It seems that I am nrushing my teeth using water from the worse one !!!

This must be true in millions of households. Many have a heating system
like mine with hot & cold tanks in their roofspace plus a hot water
cylinder. {1}. And maybe they too have their cold water in the bathroom
supplied from their tank in the roofspace.

In an old house the heating system is quite likely to be much newer (say
five to 10 years) that the cold water system (say 30 to 40 years).

In future, should I use the hot water tap (before the water runs too
hot!) to brush my teeth?

Stop worrying, the risks either way are minimal. One does not drink a lot
of water when brushing your teeth.

If you want to avoid all risk stay in bed, which incidentally is more risky
than getting up.

I've never seen an installation in a house with separate header tanks for
hot and cold.

The bathroom basin should be really be fed with mains cold water, though.
Baths and showers off the header tank to get adequate flow.

Back in 1997, before I went to the Baltics, I drank increasing amounts
of cold-tank water for a few weeks. The tank was in a cupboard, not the roof
so not very smelly.

My theory was, a few bugs would be a good thing. Don;t know how if it made
any difference, but I was drinking small amounts of water from soviet
plumbing and directly from countryside wells with no ill effect.

The woolly asbestos (probably) I found while nosing in a riser cupboard gave
me more of a start!

That's a cold water tank that supplies both cold and hot taps in
the house. If it gets hot there is something seriously wrong with
your heating system and you need to get it seen to before a tankful
of boiling water descends through your ceiling killing you (as has
happened)

However the cold water tank in my roofspace is much older and had
a damaged top and I can see the base of the tank is full of crud.

That should be the central heating header tank and if it's also
full of crud there's a liklihood your CH is too and needs cleaning
out and inhibitor added.

I think you have gor my setup wrong.

There is a cold tank in the roofspace which feeds all cold taps
(except the one in the kitchen). It is refilled from the rising
main.

There is a hot water tank in the roofspace which feeds all hot taps.
It is refilled from the rising main and not from the cold water tank.

And then, as you mention the heating header tank, there is the
heating header tank for feed/expansion of the boiler heating circuit.
That too is in topped up (if necessary) from the rising main. It is
best to ignore this tank as it is a red herring.


This must be true in millions of households. Many have a heating
system like mine with hot & cold tanks in their roofspace plus a
hot water cylinder. {1}. And maybe they too have their cold water
in the bathroom supplied from their tank in the roofspace.

Provided you have a fairly frequent turnover of water in the tank
it should be fine. However, if you've been on holiday for several
weeks in warm weather I would suggest running a few bathfuls of
water first to freshen the tank.

In future, should I use the hot water tap (before the water runs
too hot!) to brush my teeth?

No. Apart from the *warm* water being more likely to have bacterial
or other contamination, the warm water will soften the bristles of
your toothbrush, which means they will be less effective against
plaque and gum disease, and all your teeth will fall out of your
bleeding septic gingivae.

There is no mains water at all in the bathroom.
Neither in the cold tap for the basin nor in the cold tap for the bath.

The bath is normally fed with 22mm pipe to give a fast flow rate from the
header tank, and unless you like cold baths there is no point in having it
on the mains, given you're as likely to 'drink' some of the hot as the
cold when bathing.

The basin is different. Many like to have a drink of water after teeth
cleaning or whatever. Have you investigated changing it to mains? All the
pipework going to the loft may well be together and of course includes
mains. So may not be that difficult to pick up.

I think those have got sodium bicarbonate; caustic soda is sodium

If you use a water filter to rid the water of certain impurities like chlorine,
etc. it is better to use water from the cold water faucet which has been
filtered.

If your bathroom sink does not have a filter, don't use the water to brush your
teeth. Bring a glass of water from the kitchen faucet which has the water

My bathroom water smells strongly of chlorine and I never use it for anything

Um, that's the water we are talking about. Most people might use a
slightly larger but still small amount.

I see. I did not make myself sufficently clear. The water is not put
into my mouth, it is used simply to rinse the sink.



also used to rinse brush, which is then air-dried.

Ditto. it makes not difference does it if the brush is rinsed in a
lot of water or a little because the water left after shaking is
going to be the same quantity.


Weeell, there is a difference between ingesting water fresh from the
tap, and inserting an air dried (over several hours) toothbrush in
one's mouth. How much of a difference is open to debate. Dry
plastic/nylon surfaces are pretty inhospitable to bacteria, fungi, and
viruses - they normally require warmth, food, and moisture. Remove any
one of the three, and they are inhibited from growth, and die pretty
rapidly, having few resources to fall back on. Some form spores, which
can be nasty.

In general, those with poor immune systems, such as the very young, the
very old, the pregnant, those undergoing chemotherapy, those taking
anti-rejection medication and the AIDS sufferers are most vulnerable.
Pretty much everyone else has low risk. As a student, I drank and
brushed my teeth in dilute pigeon (unbeknownst to me) for months
without any major short term effect.


Do twice daily after meals.

I started doing this after visiting Africa and seeing at first hand
what people had to go through to get 'water' - actually muddy
polluted muck - to use for drinking, cooking and cleaning; then
learning how much water is wasted by people leaving taps running
while brushing teeth during a not-so-recent water shortage.

Use caustic soda for excellent results.

Some toothpaste (e.g. Maclean's Whitening, which I have some of
in the cupboard) does contain caustic soda.

I think those have got sodium bicarbonate; caustic soda is sodium
hydroxide, which is altogether different.

Yes, I know. Let me get the tube for you:

"Macleans whitening helps restore natural whiteness and keep
teeth healthy. Ingredients: Aqua, hydrated silica, sorbitol,
pentasodium triphosphate, PEG-6 (?), titanium dioxide, sodium
lauryl sulphate (my sp.), aroma, xanthum gum, sodium hydroxide,
soduim saccharin, sodium fluoride, limonene."


Caustic soda would be a very
effective tooth-cleaning agent; the problem is that it would also be a
rather effective flesh-dissolving agent as well.

It only mentions keeping teeth healthy, not gums wuggf umnumnum
blblbblb mmfff.

The message
from Chris Bacon contains these words:

PEG-6 (?)

Polyethylene glycol. The 6 tells you how long the chain is.

PEG is used in a number of toothpastes as a dispersant; it binds water
and helps keep gum uniform throughout the toothpaste. It is also used in
liquid body armor [3] and tattoos to monitor diabetes[4]. Functional
groups of PEG give polyurethane elastomers their "rubberiness", for
applications such as foams (foam rubber) and fibers (spandex). Its
backbone structure is analogous to that of silicone, another elastomer.
