Installation
Introduction
Water service lines are connections that lead from the water mains to the building plumbing network.
The service line consists of all pipes, valves, and fittings between the main water cabinet through the
meter, and ending at the individual outlets or endpoints.
DIN 1988 Parts 1 &3 apply to drinking water supply systems inside buildings and their networks. It
specifies requirements for design, installation, operation and maintenance of such systems in addition
to alterations to these systems. It also gives particular attention to materials, components and
appliances installed to supply a building with potable water. Designers and installers should make sure
that only such required equipment and appliances are installed ensuring proper economic and
technically qualified functioning of the system is maintained.
When installation is executed,

instructions should be strictly followed. Additionally,
the following must be readily available:
A building site plan; engineering drawing of each floor including cellars (plan view), with
simplified pipe work diagram and sectional drawings;
Pipe sizing calculation in accordance with DIN 1988 part 3;
A detailed pipe network diagram showing length of pipe runs,pipe nominal sizes, bore diameters,
material, draw-off points (type, number and sizes or bore diameter), minimum flow pressure
required, and the fitting group as defi ned in the of DIN 4109 series of standards, where
necessary.
