paso de agua

Thank you both Helena and bigedsenior for all your help. I'm giving the points to bigedsenior because his answer was the closest to the term finally chosen: waterway diameter. Thanks and have a nice week :)

The links where I've found "waterway diameter", one is from a Canadian site and the other from a UK site. And I've come across one from a US site. It seems they use this term when referring to the diameter of fittings. I'll keep on looking in this direction. Maybe that's the correct term in this case since this is also a pipe fitting.

Yes, I agree with you, water flow is correct when referring to the flow of water. In the link I've posted, there's also the table with dimensions I'm translating. One of the columns says "agua de paso d min (mm)". In that specific context I don't think water flow or water pipe fit. I guess bigedsenior's suggestions is closer.

I was looking at the second picture along the top, not the list of items! If you only want to refer to the flow of water itself, and not where it flows through, then I think 'water flow' is fine.

Thank you for all the information Helena.

Here they use 'water flow' and you also see 'water line'.

My answer is UK English. I don't think 'waterway' would be right for the UK but it might be ok for the US.

I would use 'pipe' simply because that's what I've always heard; I'm afraid I don't know whether you need to use 'pipe' or a 'tube' in this case.

The difference between pipe and tube is simply in the way it is sized. PVC pipe for plumbing applications and galvanized steel pipe for instance, are measured in IPS (iron pipe size). Copper tube, CPVC, PeX and other tubing is measured nominally, which is basically an average diameter.

I would use 'water pipe'. The only thing that differentiates them is their diameter and the material they're made of.

Water pipes are pipes or tubes, frequently made of polyvinyl chloride (PVC/uPVC), ductile iron, steel, cast iron, polypropylene, polyethylene, copper, or (formerly) lead, that carry pressurized and treated fresh water to buildings (as part of a municipal water system), as well as inside the building.

I've found this link http://www.ic.gc.ca/app/ccc/srch/nvgt.do?prtl=1&estblmntNo=2... where they use the term "nominal waterway diameter" when referring to the dimensions of fire hose gaskets.
And they also used it here when referring to pipes http://www.horobin.co.uk/search.asp?searchbox=450&Search.x=0...
Perhaps this is what they meant by "paso de agua". What do you think? Thank you for your time and help!

If you can take a look at the second picture in this link http://www.concyssa.com/?titulo=division-industrial-catalogo... you'll see it has two green nuts, one on top and one on the side. The client has explained water flows through the one on the side. In a similar drawing, which unfortunately I don't have online, there's an arrow pointing to the side nut and it reads " 'd' paso de agua"

The article is also available in Spanish.

Hi, Claudia. I think it's just a pipe through which water 'passes' (flows). I'm basing my suggestion on 'llave de paso' which is 'stopcock'.
