Sounds as though you have galvanised piping. Your only solution there is to take the section of piping out and inspect it at the next joint and see whether the condition of the piping is adequate. If not take out the next section of piping until you find that the piping is in better condition. My recommendation is to replace with copper, for two reasons, copper does not corrode and is easy to install. Would be advisable to replace the stopcock and even in some cases the tap as well.

There are a number of factors that determine where the plumbing contractor decides to install it. If it is a gas heater, it needs to be located where it can be vented to the outside. Typically the heater should be as centrally located as possible to facilitate hot water getting to all of the fixtures it is attached to. They will attempt to minimize the length of the piping runs. Takes less piping and less work to install.
pipe = one piping = a system of piping arrangements
