Talk:Dry riser

Untitled
It's been suggested that this article should be merged with "dry stand pipe". PLEASE DON'T. Cross reference, yes, but innocent questers after information like me might have failed to find the article if it had been merged, and might have beenless confident in its accuracy if it had the air of a transatlantic hybrid.82.45.205.207 14:57, 21 September 2006 (UTC)

I suggest this page name be changed to Dry Pipe Fire Sprinker System. In the US, the terms standpipe and riser are exclusive. A standpipe supplies water to a hose system, whereas a riser supplies water to a sprinkler system. This should be resolved with the existing Dry systems section at the Fire sprinkler page.

 * Delete reference to Fire Department Connection in intro. This position give the impression of importance, whereas an FDC fulfills a completely independent function in a sprinkler system, and is not unique to dry systems, being a part of every sprinkler system.
 * Resolve with redundant description in fire sprinkler systems article.
 * Change references to impressions of reduced water damage for dry systems. If a person is educated enough to understand the difference between wet and dry systems, I have not seen them confused by the chance of water damage with dry systems based on operational sequencing. The text is true of the impressions of single interlock pre-action systems.
 * Change "advantages of dry systems" to reflect the view that dry systems cannot be used unless there are freezing considerations. Therefore, using a dry system is not an advantage, but an unwanted necessity.

Merge content with Fire sprinkler system
I think the biggest problem here is that everyone has a different idea on what a Standpipe, Dry riser and Wet riser's are. This is probably because different countries use different terms. So I will begin with outlining what is a reasonably International definition:
 * Riser (Firefighting). Fixed pipes run through a building (usually multi-story), that are designed explicitly to aid in Firefighting by providing local sources of water in a building. These are almost always(?) separate from a Fire sprinkler system.

I propose the following (which I observe is almost the same as what Fireproeng has suggested:
 * 1) Merge the information on a Dry pipe fire sprinker system with the Fire sprinkler system article, which is a much better place for it, and a better description is already there.
 * 2) Rename this article to Riser (Firefighting). (see below)
 * 3) Expand this article to be about risers (as in, a fixed set of pipes in a building designed explicitly for firefighting), both dry and wet.
 * 4) Symlink Dry riser and Wet riser to Riser (Firefighting).

This is directly related to my suggestions on the article for Standpipe. If noone has any objections for these changes, I will work on them over the next few weeks. If anyone has any objections/comments/etc, then we can work them out. --Zaf(t) 05:26, 2 May 2007 (UTC)
 * I agree this needs to be clarified. But before we change anything, I think we ought to determine the validity of the result. If we start with verifiability, NFPA clearly references a standpipe as being used for hoses (NFPA 14), and a riser for sprinkler water supply. However, I believe the article should be written with considerations for international terminology. Can we confirm that riser is in fact the name for a water supply pipe to sprinklers in countries that do not use NFPA as their main reference? What is the source ? Fireproeng 01:23, 6 May 2007 (UTC)
 * Interesting problem. My knowledge is based on front-line use, but that is often full of slang, etc, so I am going to talk to some fire engineers here in NZ to get a clarification of what the definition of a Riser and a Standpipe is in NZ. I will also seek documentation to reference with respect to these definitions. Is there is anyone who reads this in Europe and can find an official definition of a Standpipe and Riser with respect to Firefighting? It would help to know if the definitions that the US use are unique to just the US, or if New Zealand is "going it alone" with its terminology. --Zaf(t) 05:36, 10 May 2007 (UTC)
 * My limited exposure to fire fighting training with RICAS here in The Netherlands did not indicate any where about Dry Standpipes being used to feed the sprinkler system.

 * I agree that here in the U.S. a standpipe does supply hose valves. However on multistory buildings the water supplies for the sprinkler systems on each of the floors will normally originate from the standpipe and will have it's own individual control valve, water flow switch, and drain. The standpipe as well as providing hose valves, can also be utilized for the supply of the sprinkler system as well. Atuuschaaw (talk) 16:14, 27 January 2009 (UTC)

In the absence of contrary opinions, I will proceed with edits as proposed in my 18 Mar 07 comments. Fireproeng 16:53, 16 June 2007 (UTC)
 * After revisions, I think this page should be merged with Standpipe and Fire sprinkler system, with disambiguation pointing searches for dry riser to these pages. Fireproeng 18:05, 16 June 2007 (UTC)

In the UK, the term riser is commonly used in reference to pipes used to provide water for fire-fighting. They are usually refered to either as a dry riser, wet riser. The standard guidance however uses the term fire main. The terms rising main or failing main (when serving the basement storeys) do occasionally get used.

Given that the article also is used for wet main systems not just dry mains, there is a clear need to rename. Given the general support for a rename to riser (firefighting) I will action this. NexusQuile (talk • contribs) 21:44, 5 March 2019 (UTC)

dry risers
can run a cold mains water feed up through a dry riser that is 1m x 500mm in size — Preceding unsigned comment added by 80.2.103.50 (talk) 12:43, 20 February 2018 (UTC)

Jurisdiction
The expression "have to be" is used twice. Presumably that's referring to regulations in some particular jurisdiction? CaGlwwWEDymzc7KBQC8u (talk) 08:42, 12 June 2018 (UTC)
