Types of Connections
Can someone add a section for Types of Connections? It should list : Threaded pipe Stephen Charles Thompson (talk) 20:07, 30 December 2008 (UTC)

The description of union fittings is crap. It's like a coupling but easier to use!? How is it actually different I demand to know! — Preceding unsigned comment added by 74.44.78.41 (talk) 17:46, 2 August 2011 (UTC)

Self-Cutting Tee fittings & Flamco T-Plus
Could I suggest a mention of those Tee fittings which cut their own hole into the wall of the supply pipe when clamped down? Also, Might another type, the Flamco T-Plus (PDF at bottom of that page) be worthy of mention? It's a self cutting Tee which uses an explosive charge to open a branch into pipework.

 * Sounds like a good idea to me. Reify-tech (talk) 16:55, 5 July 2011 (UTC)

what is that chemical smell on new fittings from?
does anyone know anything about why new galvanized steel pipe fittings have a distinct chemical smell? Anyone know what the chemical might be? It seems to me it might be a toxic chemical coating on it but I cant find any information about it. —Preceding unsigned comment added by 98.160.131.17 (talk) 05:37, 17 August 2010 (UTC)
 * It is probably some kind of heavy oil or wax coating to inhibit corrosion, but the actual ingredients are often proprietary and may require legal action to compel their disclosure. Ability to do this is entirely dependent on the health and safety regulatory environment in any given locality.  Reify-tech (talk) 21:22, 8 March 2017 (UTC)

Request photos and diagrams
I managed to find some decent pictures of fittings in Wiikimedia Commons, and added them to the article. More photos are needed to fill in the gaps, especially for DWV fittings. A more abstract diagram of fittings types and/or a typical layout diagram showing a DWV design might also be helpful in illustrating how fittings are actually used.

Also, the "Connection types" section is partially illustrated with some photos I was able to find, but more pix are needed to fill in for missing connection methods. Reify-tech (talk) 17:01, 5 July 2011 (UTC)

cap as air chamber
i deleted someone's paragraph, including the same information into my the origional paragraph. hope that is ok. i will not change it if the author puts it back in for some reason. — Preceding unsigned comment added by Sven nestle2 (talk • contribs) 23:45, 24 June 2012 (UTC)


 * I've removed it too. I don't think it's encyclopedic and it has no citations. Here is the paragraph:
 * "A cap and pipe is used by some plumbers to make an air chamber (offers air cushion to sudden changes in pressure that will cause pipes to knock) which is equivalent to pre-made ones for pennies on the dollar and has advantage of 'never breaking'. The tip is for residential as it may, though rarely, need drainage (the water shut off, happens whenever plumbing is done) if the air dissipates. Practically it's no worry or corrected easily.  The amount of cushion matters (a few to several inch pipe) so check into that."
 * If someone wants to add it again, please improve it first. Thanks. --4368 (talk) 19:30, 20 August 2012 (UTC)

drain pipe
How much room is needed to drain a toilet with 12" joists and wanting to slope it over to wall 24" away for draining. — Preceding unsigned comment added by 70.60.95.171 (talk) 19:06, 12 May 2016 (UTC)
 * As you have discovered from the non-response here, this is not the place to ask detailed questions about plumbing design, which are very dependent on the technology available and the health and safety regulations in your jurisdiction. Questions like yours should be resolved locally, and are inappropriate in a global encyclopedia like Wikipedia. Cheers! Reify-tech (talk) 21:26, 8 March 2017 (UTC)

Sweating?
Why are the end-fed capillary soldered joints described here as "sweated"? Sweating is a recognised form of soldering, but it's done by taking two pre-tinned parts, placing them together and then heating them, without needing to add additional solder. These fittings are untinned, and have their solder added through the end, once heated. Andy Dingley (talk) 18:19, 23 July 2016 (UTC)


 * Andy Dingley, although I think you are technically correct in some contexts, the term is widely used by plumbers in North America to describe their common technique of joining copper pipe. It is an unfortunate affectation or insider jargon, and is unlikely to change anytime soon. I prefer to call the joints "soldered", but use the term "sweated" when talking to plumbers. You are welcome to add a clarifying note, if you are so inclined. Reify-tech (talk) 21:34, 8 March 2017 (UTC)
 * Sweating (in the electrical context) means to prolong the heating to allow solder to 'soak' into the space between soldered parts.
 * The parts may be pre-tinned or solder may be applied once the parts are hot. 203.213.46.180 (talk) 23:52, 1 September 2022 (UTC)

Adding Cross-linked polyethylene (PEX)
I think adding PEX as an additional material is warranted as PEX is mentioned a few times throughout the article and has its own dedicated article. Webgyk343 (talk) 04:45, 1 December 2023 (UTC)
