I don’t work in San Francisco fire, but have friends that do. They have I think over 200 sisters continue to put them in. After the 1906 earthquake, they don’t take any chances. Plus they have high pressure hydrants that go up to 500 pounds psi. They have a Glisan valve that goes on to the hydrant to reduce the pressure if they use it for normal pumping.
It is so nice to see a city group drafting. When I was driving for a volunteer company outside of about five towns in the county, everything else was tanker or drafting.
This is a Cistern, which San Francisco has many of all throughout the city. They also have a high-pressure system with specialized pumps that pump up to 500 pounds pressure with very large hydrants throughout the city. They instantly pressure reducing valve large in size 90 pounds on those hydrants in order to decrease pressure when needed which would be always I guess.
30-45 seconds huh . Lmao this needs to be deleted and redone . Oh and done let “ Mr chauffer “ demonstrate how to draft from an underground water tank or source .
San Francisco Fire Department Auxiliary Water System. Great video.
Wow, very interesting. The old systems are the most reliable.
Nice video.
My department has approximately 30 “modern” cisterns in service.
They’ve become quite popular over the past 15 years or so in many areas.

I did not shoot this video. I downloaded it and added some back draft music...
