lead acid batteries / topping up

We have very hard water here in Hampshire. I buy Reverse Osmosis water from Maidenhead Aquatics (£4 for 25 litres I think) for my tank and insectivorous plants. It passes this test with ease. ISTR from school days you could test hardness by shaking tap, then distilled, water plus a known amount of liquid soap in a measuring cylinder and comparinging the height of the "head". It was reasonably accurate compared to evaporating to dryness and weighing the residue on a chemical balance.

Nasty stuff dihydrogen monoxide. Should be banned.

I use rainwater for insectivorous plants. I have occasionally used brita filter jug water, and that seems to be OK too.

"Inhalation: No symptoms".

Really?

Warrington's water is so hard now, if Jesus tried his party trick the locals would say "so what, I do that to cut 10 minutes off my walk to work".

We tend to throw away 1 kettle a year because even through we descale every couple of weeks, it works into any joints so when you clean it it eventually leaks.

And addictive. I've never known a regular, or even casual user who could live without it for the rest of their lives after even one experience.

Flippin heck I thought St Albans was bad with a descale every month or even here before they switched the feed from the limestone adit on the hillside a mile away to Burnhope Reservoir.

Guess you need to find a good old fashioned metal kettle not some flimsy snapped together plastic thing.

My local car bits shop tells me the only thing they can sell to kids under
