Frequently asked questions about the Water supply category
Water supply — what is it and which products does the category include?
Water supply — includes products for delivering and treating water: water pipes (PPR, steel, PEX-AL-PEX), fittings, water pumps (surface pumps and pump stations), water filters (AQUAPHOR), taps and valves, pipe insulation and fastenings.
How to set up water supply for a private house from a well — which components are needed?
Typical setup from a well includes a submersible or surface pump, pressure vessel or storage tank, piping (PPR or PEX-AL-PEX), coarse and fine filters (AQUAPHOR cartridges available) and a non-return valve.
Which pumps suit water supply for a private house?
Use submersible pumps for deep wells or surface/self-priming pumps and pump stations (brands like AL-KO, Scheppach available). Choose based on power (W), maximum head (m) and flow rate (l/min) matching household demand.
How to set up water supply for a private house with a storage tank?
With a storage tank use a surface or submersible pump, float level control, pre-filtration and piping in PPR/PEX-AL-PEX. Tank should have maintenance access and connect to a pressure vessel or pump station to maintain system pressure.
Which water filters suit city and countryside water systems?
City water: cartridge filters and AQUAPHOR replacement modules for fine purification. Well water: staged approach — coarse pre-filter, carbon/AQUAPHOR filter for taste/odour/chlorine removal, then mechanical fine filter.
Which pipes are best for outdoor and indoor water supply?
Indoors: PPR and PEX-AL-PEX are common for corrosion resistance and easy installation; outdoors: steel or reinforced PEX-AL-PEX with proper insulation against freezing. Choose diameter by flow demand (typically 20–32 mm for house mains).
How do fittings differ by material?
PPR fittings are welded thermoplastics; press fittings suit metal-polymer and steel pipes for quick joints; brass fittings are durable for indoor/outdoor use. Choose based on pipe material (PPR/PEX/steel) and installation method (weld/press/thread).
Which shut-off taps and valves to choose for a water supply system?
Common household choice: brass ball valves (½–1") for supply lines, shut-off valves with threaded or press connections; a non-return valve is recommended on the pump suction. Check operating pressure rating and compatibility with your pipe type.
How to choose water filters and replacement cartridges for well and municipal water?
Select by purpose: mechanical filtration 5–50 µm cartridges, carbon or AQUAPHOR cartridges for taste/chorine removal, and softening modules for hard water. Verify compatibility of cartridge size with the filter housing in the product description.
What fastenings and insulation are needed for outdoor water pipes?
Use stainless or galvanized clamps and brackets plus pipe insulation of adequate thickness (min 20–30 mm) with protective outer jacket. Insulation prevents freezing and heat loss; select moisture- and UV-resistant materials.
How to design water supply for a multi-storey residential building — which elements matter?
Essential elements: pump stations with redundancy, larger distribution mains (typically ≥32 mm for floors), water meters on risers, inlet filtration and pressure control systems. Design must account for consumption, pressure drops and fire-fighting requirements.
