Yes i agree, plumbers in the our country (United Kingdom) undertake
installation of domestic internal hot and cold water pipe work,
fittings and related soil and waste pipe work systems.
Domestic, commercial and
industrial gas-fired (central) heating
installation, servicing and repair works,
and works related to all
other gas fired appliances, although done by plumbers,
involve other trades such as pipe fitters, gas fitters etc.
