Stop valve

This serves to shut off the entire drinking water installation or at least individual
sections of the pipes. Repair and maintenance work can involve having to shut off
the supply. The pipes can be shut off centrally, for example at the cellar distribution
point in the main supply connection room or in an apartment itself. The most common
form of stop valve is an outlet valve but also piston valves and ball cocks.
schliesen
Water meter

It serves to measure water consumption for a house or an apartment. In houses it
is installed at the point at which the water pipes enter the house. In houses divided
into several apartments where the water consumption is invoiced per apartment the
meter is installed at the end of the respective water pipe at the respective point
of delivery or in the apartment at the feeder to the drinking water rise pipe.
In accordance with calibration laws the water meter must be recalibrated every six
and five years in the case of warm water and cold water respectively. The year in
which the meter was calibrated is recognizable by the anti-tamper seal. On one side
the year is imprinted and on the other the identification number of the testing
laboratory or the measurement office.

Stop valve with integrated backflow prevention device

makes it possible to shut off the pipe, do maintenance work on the pump and prevents
hot water being run off from the circulation pipe system. Once a year it should
be inspected to ensure it works properly.

Frost-proof garden tap with backflow prevention device

The frost-proof stop valve is installed between the indoor and outdoor area of buildings
so that water can be removed for watering and cleaning purposes. As it is frost-proof
the fitting ensures water can be removed the entire year round in the outdoor/ garden
area. It is not necessary at the start of the frost period to let off water in the
feeder to the fitting. The run off taps are fitted with screw-on tubing and can
be protected against unauthorized run-off of water either by activating a key or
removing the operating handle.
schliesen
Combined filter / pressure reducing valve (PRV)
Filter:
protects the drinking water system against contamination (e.g., by grains of sand
or particles of rust), which can cause corrosion damage. Installing a filter – either
a fine filter or a backwash filter is recognized technical practice and mandatory.
The filter should be rinsed every two months, a fine filter should be exchanged
every six months.
Pressure reducer:
In the drinking water system its job is to reduce the high pressure in the connecting
pipe to the drinking water system to the maximum admissible working pressure of
5 bar and reduce the amount of water running out at the point of delivery (tap).
Pressure reducing valves are generally installed centrally in the cold water piping
down the line from the water meter.
schliesen
Leak protection system

protects the building from water damage and complements the drinking water system
after the domestic supply. Water damage is prevented as any leaks that might occur
are identified at an early stage and consequently the drinking water plumbing is
automatically switched off by the leak protection system.
schliesen
Water softening system

OPTIONAL: Is recommended in some regions if the house is located in a water supply
area with hard water. Depending on the technology employed a chemical or physics
reaction counters furring of the drinking water system and household appliances
connected to the water system. It reduces the amount of soap or cleaning agent required.
Regular maintenance is essential. The water softening system is equipped with a
safety device (e.g., a system break), so that it can be connected to the drinking
water system.
schliesen
Dosing device

OPTIONAL: Should be selected together with the plumber in some instances if the
house is in a water supply area with hard or aggressive water. It adds mineral substances
to the drinking water, which act as corrosion protection and counter the formation
of lime scale. It also makes it possible to increase the ph value. Dosing hinges
on the water quality and piping material and takes the form of liquid concentrates.
Dosing devices should be regularly inspected and maintained once a year.

WC cistern

The cistern is used to store water for flushing the toilet. It comes either as a
concealed version or a model in front of the wall. The cistern is operated by pushing
a lever, and can also be fitted with an economy function (3 or 6 instead of 9 liters
flushing water) or an electronic toilet control system. The cistern fills up again
after use.

Shower head with hose

As opposed to fixed shower heads the hand-held version can be removed from its mounting

heads boast different settings for the flow of water and intensity of the jet of
water; the different functions can be set using a revolving ring on the shower head.
Several shower heads feature a massage function, which involves the water flowing
in a thicker jet and under greater pressure.

Drinking water is our most important foodstuff
The requirements of drinking water in Germany are laid out in the Drinking Water Decree (2003).
For water to be suitable for drinking, cooking, and washing it must satisfy stringent requirements in terms of its chemical contents and microbiological composition, as the enjoyment or use of drinking water must not endanger a person’s health. It therefore needs to be free of pathogenic germs and the sort of chemical substances that can cause illness. Drinking water should also be an enjoyment, in other words be colorless, clear, cool and impeccable in terms of odor and taste.
On its journey from the entrance to the building to the tapping point, drinking water comes into contact with various materials (pipes, valves etc.). However, the quality of the drinking water must not be impaired. Though the Drinking Water Decree does not stipulate the use of specific materials the selection of materials is discussed. If the generally recognized technical rules are adhered to in planning, constructing and operating of a drinking water installation, the requirements of materials are considered met. The former are outlined in standards and regulations.
As of the point at which drinking water enters a building, the owner or landlord is responsible for its quality. As these, as a rule, are unfamiliar with the requirements of a drinking water installation, planning, construction and regular servicing should in any case be left to a specialist company.
