I had no idea, but, I do now

I knew what this was when I was 5 years old.
Are people really unware of what this means????

Well... One less mystery on our hands...
Fascinating.
I didn't know, and I still don't know as it's not really that interesting.
I've always been amazed that there are so many helicopter landing pads around the country. There's even one near my house!

Are they something to do with Steps?
H from Steps grave.

I knew what that was when I was 4 .
Steps have been going longer than I thought.
There's one in the woods behind my house...and my dad told me about them. Then, he was in the AFS during WWII...Originally Posted by Lampoc
That's interesting that the hydrants are below ground I am curious as to why. Over here they are all above ground I would think it's easier to connect the hoses to the hydrant above ground.
I also knew from a very young age.
I rather like marker posts and plates indicating things that are important but out of sight.
Probably purely historical, but they're less exposed to traffic damage and vandalism than above ground hydrants. Lift the cover, add one of these:
...and away they go.
Frost, they are not subject to extreme low temperatures when underground.

Me too

"Once is happenstance. Twice is coincidence. The third time it's enemy action."
'Populism, the last refuge of a Tory scoundrel'.
I knew what they were, but didn't know what the numbers meant, or that you shouldn't park over one. Presumably they'd have double yellow lines nearby, I've never noticed.
SV - Sluice Valve, what's WO?I rather like marker posts and plates indicating things that are important but out of sight.
I knew what it meant whilst I was still in the womb.
Or, more commonly I believe, 'stop valve'...as for WO (I had to look it up) it's Wash Out, the official name for a flushing point.
Now for AV...
Edit: Apparently it is Air Valve, these "air valves will discharge air from a non–pressurized pipe enabling the efficient filling of the pipeline; continuously release air from a pressurized system, preventing the build-up of air pockets in the pipeline and admit large amounts of air into the system when vacuum conditions occur, protecting the pipeline from pressure transients and possible collapse."
PS I don't believe that there are routinely parking restrictions around hydrants.

Out here in the boonies they are often hidden in the overgrown verges of country lanes, a recent addition has been to paint a yellow H on the tarmac with an arrow pointing to the verge so that the fire brigade might stand a better chance of finding them
PMSL!!
Was taught about them at primary school.
I had dozens of I-Spy books when a nipper and loved 'em. Full of stuff like this. How times have changed...
Some hydrants have a frost valve, which allows water to drain out of the main body and stop it freezing up.
Top number is the diameter of the main in mm, bottom number is distance from the post to the hydrant pit in m to enable finding it if there's snow on the ground, or if overgrown etc. If you lift the hydrant lid and turn it over there should be an enamel disc with an arrow indicating the direction of opening with the key and bar. On an old plate the numbers would be smaller and be inches and feet. The water maps on a fire appliance will show each hydrant with a colour coded circle to also give the pressure and flow.
F.T.F.A.
Pah! I knew what it meant when I was just a glint in the milkman’s Eye...
My hypnotist has just informed me that I was aware of what these were in an earlier incarnation as an amoeba drifting through the primordial soup.
I invented them.
But I gave you the idea.
Probably lots of folk have no idea what these are.
I recall remarking upon their function before the Big Bang.
Is it an issued wall?Probably lots of folk have no idea what these are.
or maybe an Ordinance Survey Benchmark.
OS Trig point?

Go on then I'll go to 3
Please...and just to add some are imperial measurements and some are metric.
You'll find one there, but otherwise they may be shown on maps as 'BM'.

Bench Mark?
That's the one. See Benchmark (surveying) and OS map abbreviations.
My apologies to vRSG60 for giving a clue and the answer.
We have 'm too:
About heli landing spots: a friend of a friend (I only meet him at birthday parties) is helicopter pilot on an ambulance helicopter. His working area is the eastern part of The Netherlands (where I live). He told me that he's always observing spots with a 'can I safely land here?' attitude. He often goes out on a cycling trip and he's always making pics of open patches of land, squares in villages etc. A lot of these spots are already 'survey'ed' but he wants to see them IRL.
Menno
No worries. You can put map coordinates in here and it gives a list of local BMs
I knew but then I'm old. Would make an interesting thread...what's that sign?
Seriously , we had them explained as part of the tufty club. We had a fireman in full uniform explain the importance of not messing around with them or blocking them. I might even have been younger than 5.
