Plumbing regulations and Qualpex

socio

Hi all,

Slightly confused about the plumbing regulations on the Dublin City Council website (http://www.dublincity.ie/main-menu-services-water-waste-and-environment-your-drinking-water-builders-and-developers). Specifically in relation to polythene pipes which it says should not be used for hot water. This seems really odd as I understood pex widely used. Is this just out of date (1975) or am I missing something?
What are the current regulations and practice regarding using pex for central heating, drinking water, and hot water from combi boliers etc?

Cheers.

Qualpex shouldn't be used coming off the top of of the cylinder. This is is qualpexs own rule I think rather than the regs. It's fine for hot and cold water and heating systems. I haven't done a boil in 30 years but I assume you'd have to use copper around the boiler.

1975would indicate that their talking about the black heavy gage water mains pipe, sometimes used in light gage.

Totally different from pex pipe,
