Ive looked all over the place for what a yellow fire hydron stands for but can only seem to find every other color except yellow. Reason i ask is because in my town we have yellow hydrons all over the place.

A Yellow fire hydrant is usually considered a Class B hydrant with a flow of between 500 and 999 GPM (Gallons Per Minute). Sometimes this class of hydrant is also colored orange. A Red hydrant-Class C has less than 500 GPM flow, a Green hydrant-class A has a flow between 1000 and 1499 GPM, and a Blue hydrant-Class AA has over 1500 GPM flow. Sadly some hydrants are painted White which means they are dead and have no flow.

There are also two types of fire hydrants used, wet hydrants and dry hydrants. As the name suggest, wet hydrants have water in the barrel at all times and are connected to the town water supply, just by opening the valve pressurized water is supplied to a fire engine. Dry hydrants can also be connected to the town water supply but the barrel is emptied by a dump and waste vale to prevent freezing. Some dry hydrants are connected to a static water source such as a pond or river, in order to get water from them an engine must connect a hard suction line to it and use the engine's pump to draw water from the supply source, this is called drafting.

That is what it's like in my county. Only hydrants painted black are dead or no longer in use. But sometimes we get people who vandilise hydrants and they pain them different colors making it hard to know what Gpm it flows.

thus strengthening my theory that people are freakin idiots

So what flow rate is a hydrant painted like a "Clown?"

I know my area uses yellow only because it is easy to see at night and it doesn't blend in with the grass. They also cover them with the reflective powder you see on the road striping. Furthermore, they mark the road with a blue reflective turtle and put a sign of some kind usually a no-parking sign next to the hydrant.

I have never heard of at least in Washington State that a different colored hydrant means a different flow rate. Interesting and good idea though.

in my area, fire hydrants are all yellow.  We can tell the different capacities by the color of the caps.

Ours are all red. Unless a property owner paints the one in their front yard a different color.

The ones at the bottom of the hill flow better than the ones at the top of the hill.

Now they are all turning silver.

i live on "the Hill," a neighborhood in St. Louis which used to be known as "Dago Hill" until we got all PC...just about every hydrant is red, white, and green for the Italian flag.  i like the concept of different colors exc. that people will paint them over, and some of the older paint is lead-based.  Marie517, i'm not a spelling Nazi, but everyone here should be able to spell "hydrant" meaning a water-delivery system, as in "hydro" for water.  who knows what a "hydron" is?  sounds like an enemy on Dr. Who.

Maybe. Especially since our deptartment just raised taxes in our district.
