Plumbing - domestic engineering The municipal waterworks supply hygienically safe drinking water at a pressure of 6-9 bar up to the water meter in every property. Our task as plumbers is to lead this precious foodstuff from the in-house water distributor through an approved installation system to the last tapping point. A part of this water is led as cold water via a fine filter and a pressure reducing valve today mostly with chrome steel or plastic pipes directly to the tapping points. Another part of the water is led to a water heater and treated by adding energy and supplied as hot water to the tapping points. A circulation pump or electric heat tracing is installed to keep the hot water warm in the circulating lines. Some of the water is piped directly to the garage and garden tapping points using the existing high pressure. Depending on the existing water hardness, a water softening system can also be installed to prevent limescale residue on shower partitions or in cooking pots. The water consumed by the various sanitary appliances is collected by a wastewater piping system, which is also approved, and fed to the sewer system through wastewater downspouts. These components of the sanitary system are designed by us and installed by our qualified sanitary fitters. The maintenance and service works of sanitary systems are also part of our daily tasks. Boiler descaling, the replacement or exchange of defective pressure reducing valves, the repair of all fittings such as bath mixers or sink mixers are the most common tasks of our service fitters.
