Not sure why it got the name johnny pump...might not be true, I just fixed some formatting errors. —Preceding unsigned comment added by (talk) 02:56, 25 March 2008 (UTC)

I have a picture of a cross-cut fire hydrant I took recently; I will edit it and post it when I get the chance. RealGrouchy 23:54, 8 Jun 2004 (UTC)

The file appears to be corrupted (by having turned off the camera before it finished writing the picture). I will attempt to recover it, and if not, I'll remove these comments. - RealGrouchy 14:55, 10 Jun 2004 (UTC)
I was unable to recover that file. I'll leave the previous comments up unless someone thinks they should be deleted. - RealGrouchy 02:22, 11 Jun 2004 (UTC)

Injected fire hydrant[edit]

I am trying to find information on the injected fire hydrant. Any help in this regard would be greatly appreciated - ashattock 14:21, 27 Mar 2005 (GMT)

I have scans of the Greathead injector hydrant. Is this what you are referring to? I believe these are public domain. I may have some text. Zzorse 13:40, 27 March 2006 (UTC)


Found this image. May want to put it in. Gives internal details. Image:Firehydrant.png J. D. Redding 21:54, 22 May 2007 (UTC)

Image removal[edit]

I've removed the police car image, as I felt it didn't really add anything the article and is wholly inappropriate. We only have the uploaders word that this is an illegally parked police car which amounts to original research. It appears to be taken with a camera phone, so the quality is lower and the context is not clear. We don't know if the police parked there during an emergency situation, or if they're permitted to park there as police in that particular location. The article is also not a gallery and with a long line of images on one side already, this not so big article has got a lot of images.--Crossmr (talk) 03:31, 3 September 2008 (UTC)

Hydrants and dogs[edit]

Too bad there's nothing about "hydrants in popular culture". The fire hydrant is often associated with dogs, presented as a canine version of a toilet bowl, a place where dogs mark their territory. It appears on many pet products for that reason. —Preceding unsigned comment added by (talk) 20:50, 15 March 2009 (UTC)

Photo request[edit]

This photo request was copied from Wikipedia:Requested pictures/Architecture. Tim Pierce (talk)

Unused fire hydrant - that is before it's being set up. Eventually a photo of where it's being placed. The purpose is to illustrate the construction and functions of it in a photograph. —Preceding unsigned comment added by EPO (talkcontribs) 11:52, December 3, 2006

HD hydrant sign (UK)[edit]

Some hydrant signs in the UK bear a stylised HD symbol (with the upright of the D being formed from the right leg of the H). What's the difference between a hydrant signed H and one signed HD? (talk) 15:26, 21 April 2011 (UTC)

The "D" is for "Double" indicating two outlets in one hydrant. Nick Cooper (talk) 09:41, 18 July 2013 (UTC)

For Ireland and the UK, hydrant wrench and the fire hydrant coverage[edit]

For Ireland and the UK, both the hydrant wrench and the fire hydrants themselves should have better coverage, including pictures of the connections in the street. --DThomsen8 (talk) 14:56, 18 August 2012 (UTC)

San Francisco's Golden Hydrant ought to be pictured/mentioned[edit]

It's the most famous fire hydrant in the world, I'd bet. I'm not much of a wikipedian but just saw this article via reddit and the absence of the golden hydrant was my first thought. If whoever's invested in this article is around, here're some sources:

And it's mentioned in this article,_San_Francisco

There have been hundreds of patents issued over the years for hydrants. To just mention Birdsill without saying how his invention was different from all the other inventions seems out of place. Kendall-K1 (talk) 17:14, 30 January 2016 (UTC)

I think that it has already been explained in the first line. Seems pretty self explanatory to me. He was the first to implement that idea. If you have further history, I would say to go ahead and add it. These hundreds of patents issued over the years have all come after his initial application. The information was put in originally by a previous editor and referenced accordingly. See Wikipedia:Verifiability, not truth. Since apparently you know something on this subject, then expand the article, with references. The Birdsill Holly article had over 10,000 views worldwide on the day it became a Did You Know article on January 28, 2016. I would think if there was any objections by people in general, somebody would have said something. So far, no objections to these points that I reentered in this article (which is also in the Holly article). Now there may be some more future history = go ahead and expand the article. That's what the encyclopedia is all about, sharing knowledge.--Doug Coldwell (talk) 20:05, 30 January 2016 (UTC)
  • Did you know that Birdsill Holly invented a water pumping system for city mains that not only supplied drinking water for domestic service, but also furnished water under pressure for fire hydrants? --Doug Coldwell (talk) 20:20, 30 January 2016 (UTC)
I don't see where that says anything about how his hydrant is different from the ones that came before it. That line says nothing about his hydrant. And we have at least two editors who object to including this paragraph without more context. Kendall-K1 (talk) 21:02, 30 January 2016 (UTC)
If you have something constructive to add I recommend you expand the article and furnish references. Thousands of people have looked over this exact information in the Birdsill Holly article and nobody has had any objections to the information or the associated references. You can not take out referenced information just because you don't like it. If I were you, since apparently you are familiar with the subject, I would expand and improve this article AND don't forget to furnish the references.--Doug Coldwell (talk) 21:50, 30 January 2016 (UTC)
I'm afraid I won't be able to do your research for you. Kendall-K1 (talk) 04:17, 31 January 2016 (UTC)
The Coffin patent U.S. Patent 80,143 shows a modern fire hydrant and it came before the Holly hydrant, ergo, Holly did not invent the fire hydrant nor contribute anything substantial to its development. Holly's great invention was his water supply system and text can be added to History of water supply and sanitation Zzorse (talk) 14:10, 31 January 2016 (UTC)

Copy vio problem[edit]

The wording under History has been removed since it is almost a direct copy from page 45 of the book The Great Columbus Experiment of 1908: Waterworks that Changed the World By Conrade C. Hinds.

History (now removed) - The invention of a post- or pillar-type fire hydrant is generally credited to Frederick Graff, Sr., chief engineer of the Philadelphia Water Works around 1801. It had a combination hose/faucet outlet and was of "wet barrel" design with the valve in the top. It is said[by whom?] that Graff held the first fire hydrant patent, but this cannot be verified because a 1836 fire in the US Patent Office destroyed many patent records.
Source writing - The invention of a post- or pillar-type fire hydrant is generally credited to Frederick Graff, Sr., chief engineer of the Philadelphia Water Works around 1801. It had a combination hose/faucet outlet and was of "wet barrel" design with the valve in the top. Graff was superintendent and engineer in charge of Fairmount's waterworks department until his death in 1845. During his forty-two year tenure, Graff's many invention and system improvements set a standard of excellence for water authorities around the world. It is said that Graff held the first fire hydrant patent, but this cannot be verified because a 1836 fire in the US Patent Office destroyed many patent records.
  • Please do NOT reenter this information as it is a copyright violation.--Doug Coldwell (talk) 13:12, 31 January 2016 (UTC)
Furthermore Hinds text is borrowed almost verbatim from the web. Not a reliable source. Zzorse (talk) 14:01, 31 January 2016 (UTC)
FYI, Hinds book was published in 2012. The webpage 2014. So I would guess the webpage copied from the book = just a guess!--Doug Coldwell (talk) 16:21, 31 January 2016 (UTC)

Conrade C. Hinds[edit]

Here is some information on the author Conrade C. Hinds = the person that wrote "The Great Columbus Experiment of 1908: Waterworks that Changed the World." --Doug Coldwell (talk) 16:16, 31 January 2016 (UTC)

His book is not a reliable source for the fire hydrant article. His text is copied from the web.
From 2002 the text starting with this phrase,
The first "post" or "pillar type" hydrant is generally credited to Mr. Frederick Graff...'
and seen here at
appears almost verbatim in Hind's 2012 book,,749&f=false
Zzorse (talk) 16:38, 31 January 2016 (UTC)
The publisher of his book is The History Press = United Kingdom's largest publisher of specialist history. I would not think this publisher would want to get involved in stealing information ("copy vio") from an insignificant web page developer. HOWEVER, I would believe visa-versa. In other words I am saying the webmaster's web page was updated AFTER 2012 (to copy the book), in spite of what he has written at the bottom of his web page. I put my faith in the publisher and author, not the webmaster.--Doug Coldwell (talk) 12:42, 2 February 2016 (UTC)
That doesn't explain why is saying that they were served this page in 2002. Like you, I could picture a webmaster failing to update the dates at the bottom of his pages. But how do you explain the Archive timestamp?
Whatever the explanation (and there may well be one), that web page looked like that in 2002. TypoBoy (talk) 21:09, 3 February 2016 (UTC)


I notice that another's later patent at the U.S. Patent Office refers to Holly's fire hydrant -AND- patent "Smart monitor for fire hydrants"

History section[edit]


I have added back in the History section previously deleted. This is a significant part to how fire hydrants work and how the idea of water pressure needed for their operation was developed by Holly initially. This first came about by Holly's techniques to develop this water pressure. Today we use very high water towers. There has been over 11,000 viewers that have viewed the Holly article that has explained this and nobody has had any objections to the information or references provided. Please explain your reasoning BEFORE removal of this important part of history of the operation of the fire hydrant.--Doug Coldwell (talk) 11:52, 2 February 2016 (UTC)

  • The Did You Know line on the main page for 28 January 2016 was
... that Birdsill Holly invented a water pumping system for city mains that not only supplied drinking water for domestic service, but also furnished water under pressure for fire hydrants (Holly fire hydrant pictured)?
  • There has now been over 12,000 views for the article and nobody has said anything about this information being incorrect. Apparently you are the only one that has any objections.--Doug Coldwell (talk) 14:27, 3 February 2016 (UTC)

Gallery of pictures[edit]

Please don't remove pictures BEFORE giving reasons for doing so. The Gallery of pictures shows Holly's fire hydrant of 1869 and how close it represents today's version, some 150 years later.--Doug Coldwell (talk)
