i watched several training video from usa firefighters. ALLWAYS FLUSH THE HYdrant. to clear inside from debries or other things and verify it's working.

First minute of this video i was wondering why he was doing this next to an airport. Then i realized i had a jet starting playing in another video.

good video it helped us sell the assist valve concept on long supply line lays

Dont forget to mention that dressing the hydrant out completely with two 3 inch lines maximizes your water supply.

Great vid. Thanks!

Never could understand why the dry hydrants don't have a gate or ball valve on the smaller 2.5 ports which would allow you to open those up separately after opening the top operating nut to charge the hydrant..
I've seen very few that have this particular design on the dry barrel hydrants..
Of course the advantage of the wet -barrel hydrants is that you can open each one of the ports separately allowing you to run each additional line at a time after you have your steamer connection in service.

Hydrasist was created before the Humat valve; so, Hydrasist is the old valve. lol

Looks like an easy way to water hammer your mains right out of the ground.

at  1:41 it was said NOT TO FLUSH THE HYDRANT. why would you not flush your hydrants when the is a fire???

we should ensure the hydrant is operational and that if there was items inadvertently or purposely put into the hydrant that they are flushed especially at a working incident.

Good video, thanks. What is the name of the valve on the hydrant? I am doing an article on an ancient 4 way valve from Baltimore and could use background on other valves. Thanks

Not flushing is stupid because you can learn about the hydrants current conditioning, and keeping things in the off position just adds an unnecessary step

Really informative but it seems like a lot of work and complexity to supply one line. Wouldn't a five inch into engineer's intake and five inch out the officer's discharge do the same thing?

Why don’t you use a manifold with 4 valves on it? Way more easy to use and to connect.

These things are a bitch when catching a hydrant.

How did you close the other 2 gates?

can another fire department get water from the same hydrant
