Key points about Drinking water installations
Drinking water installations must remain hygienic and safe in operation over the long term. Suitable materials, correct pipe routing, appropriate temperatures and avoiding stagnant water are key. TOPAL works on drinking water systems in accordance with the applicable technical rules.
Technology and planning at a glance
Hygiene through good planning
Unused pipe sections and long periods without water flow may impair water quality. Routes and draw-off points should therefore be sized and planned according to actual demand.
Consider hot and cold water separately
Temperature control and insulation affect hygiene. Cold water should not warm up unnecessarily, and hot water must be supplied in line with the applicable rules. Blanket temperature settings without knowledge of the system are not advisable.
Materials and safety
Pipes, joints, fittings and protective devices must suit the particular installation and be approved for their intended use. Required testing and flushing procedures must be considered after modifications.
How the project is prepared and carried out
- Clarify the task
Distinguish new construction, remodeling, pressure problems, pipe damage or modernization.
- Plan the installation
Determine draw-off points, pipe diameters, shut-off valves and necessary protective measures.
- Install correctly
Join suitable components professionally and avoid unwanted dead-end pipe sections.
- Test and commission
Carry out the required tightness tests and commissioning procedures after the work.
Information to include in your enquiry
Please provide the building type, number of water outlets, existing pipe materials and purpose of the enquiry. Photos and details of the affected pipe are useful where damage is visible.
TOPAL operates in Gelsenkirchen and the surrounding area. Availability at a specific location and the possible appointment date will be agreed when you enquire.
Frequently asked questions about Drinking water installations
Why is stagnant drinking water a problem?
Water left standing for long periods can worsen hygiene conditions. Pipe routing based on demand and proper use are therefore important.
When should old drinking water pipes be replaced?
Not solely because of a particular installation date. Material, condition, corrosion, hygiene, remodeling plans and technical requirements all matter.
Are domestic hot water and heating water the same pipe system?
No. Drinking water is subject to different hygiene requirements from water circulating in a closed heating system. Proper separation and protection are necessary.
