Hydrant signage question
Random question here...
I know that the "H" sign stands for Hydrant, and that the numbers
above and below the H specify bore and distance respectively. But I
have recently seen a few "HD" signs, again yellow, with numbers above
and below the H, and with the H and the D merged together.
Purely out of curiosity can anyone tell me what these mean? Also, is
there any way of knowing whether it is a new, metric sign, or and old,
imperial one?
Cheers,
Ben

Re: Hydrant signage question
Hydrant double, Double outlet.
Metric signs will have bore in mm so will be significantly larger.

Re: Hydrant signage question
I seem to remember the plate appearing in an old manual of firemanship
and believe it referred to a double hydrant (possibly two pits close
together?)

Thanks :-) Its amazing what you can find out on the web.
In relation to the second point it occurred to me that it should be
obvious whether the sign is metric or imperial, since 100mm bore is
reasonable, but 100" would just be silly!

Re: Hydrant signage question
I seem to remember the plate appearing in an old manual of firemanship
and believe it referred to a double hydrant (possibly two pits close
together?)

Re: Hydrant signage question
Hydrant double, Double outlet.
Metric signs will have bore in mm so will be significantly larger.

Re: Hydrant signage question
Hydrant double, Double outlet.
Metric signs will have bore in mm so will be significantly larger.
