Frequently Asked Questions – Water, Gas, Heating, Sewerage, and Filtration Systems
Valrom offers a complete range of pipes, fittings, and accessories for water supply, natural gas, sewerage, and heating systems, manufactured from durable materials such as PE, PVC, and PP.
The pipe diameter is chosen based on the desired flow rate, system pressure, and route length. If you are unsure, it is recommended to consult a specialist or designer.
PE pipes are resistant to corrosion, high pressure, and thermal shocks, offering a long lifespan and simplified installation in potable water and natural gas networks.
PVC is excellent for medium-pressure and gravity sewerage systems, while PE offers superior flexibility for long routes and difficult terrains.
Sound-absorbing systems are designed to reduce noise produced by water flow in pipes and are ideal for residential buildings or spaces where acoustic comfort is important.
There are mechanical filters, activated carbon filters, water softeners, and reverse osmosis systems, each suitable for removing specific impurities from water.
Reverse osmosis forces water through a semi-permeable membrane to eliminate contaminants, heavy metals, and chemicals, providing high-purity drinking water.
Nominal pressure indicates the maximum pressure at which a pipe or fitting can safely operate; it is essential for the correct sizing of networks.
Gas network installations must be carried out by authorized technicians, in accordance with legislation and safety standards, to avoid the risk of leaks or explosions.
Emptying depends on usage and size, but it is usually recommended at regular intervals to prevent sewerage blockages and unpleasant odors.
Blockages occur due to fats, textiles, food waste, or heavy substances being discarded into the sewerage system; prevention includes grease separators and periodic maintenance.
Signs include radiators being cold at the top, noises in the system, or inefficient circulation; proper venting eliminates trapped air and improves performance.
Anti-magnetite filters protect the heating plant from metallic particles in the system; choose a model with a magnet and a sieve for maximum mechanical filtration efficiency.
Filters must be cleaned or changed according to the manufacturer's recommendations to maintain flow and filtration quality; neglecting this leads to decreased performance.
The installation of a heating plant must comply with local regulations and be carried out by an authorized installer. Valrom recommended pipes and fittings are used to ensure the tightness and durability of the installation.
Electrofusion fittings are special accessories for polyethylene (PE) pipes, which are electrically welded to ensure durable connections, used in gas and water networks.
The use of non-corrosive materials such as PE, PVC, and adequate protection of metal components are essential for preventing corrosion in water and gas supply systems.
Watertightness ensures that there are no water or gas leaks in sewerage systems, guaranteed by the use of correct materials and joining technologies, such as rubber gaskets and appropriate welds.
Maintenance includes pressure checking, radiator bleeding, filter cleaning, and periodic inspection of pipes and connections to prevent leaks and malfunctions.
A hydrophore is a water pumping and storage system that maintains constant pressure in the network. It is recommended in areas with low pressure or unstable water supply.
The choice depends on the quality of the source water and the impurities that need to be removed. Water analysis and a specialist's recommendation are essential for selecting the optimal system.
Gas leaks, blockages, and corrosion are the most common problems. Prevention consists of regular checks, correct installation, and the use of certified Valrom materials.
Sewerage installation must comply with local regulations and European standards, which stipulate appropriate materials, correct slopes, and tight connections for optimal operation and durability.
Optimizing insulation, adjusting thermostats, using efficient pumps, and periodic maintenance of the installation contribute to reducing energy consumption.
Gaskets ensure the tightness of connections, preventing leaks and ensuring the durability and safety of the piping system.
For corrosive environments, polyethylene (PE) and PVC pipes and fittings are recommended, as they resist chemical agents and humidity.
Testing is done by pressurization and visual inspection for any leaks, in accordance with current regulations, to ensure the safe operation of the networks.
Underfloor heating offers uniform thermal comfort, high energy efficiency, and freedom in arranging spaces without visible radiators.
Regular replacement of filter cartridges and cleaning of components are recommended to ensure water quality and optimal system operation.
