Concerning the admissible working pressure for fixing material made out of UPVC we refer to the PN-data for the accoutrements (20°C and Water). For different temperatures or mediums please make reference to our product management.
Advantages of the UPVC-System
The material UPVC is characterized by its hardness, dimensional stability and exceptional chemical resistance which result from the interaction of the chlorine atoms in the polymer chain. These characteristics predestine the material UPVC to be used in the production of pipe installations under pressure.
Behaviour of UPVC when used outside
UPVC is weather resistant in middle European climate zones north of the Alps even under the influence of the short wave UV-parts of the sunlight. Nonetheless UPVC loses a little bit of its impact-resistance and therefore it is to your advantage to protect the material by using an Isolation system, a cover or a protective coating in case the product is used under extreme conditions.
Chemical resistance
UPVC has an exceptional chemical resistance, even under the influence of high temperatures or medium concentrations. In comparison to a multitude of dilute or concentrated acids and bases , alkalis and aliphatic compounds, UPVC is rated as resistant. It shows weaknesses when confronted with mediums like ester, ketone, chlorinated hydrocarbons and several other solvents. UPVC is not resistant towards strong oxidants.
The chemical resistance depends on multiple factors, for example the operating temperature, the operating pressure, the concentration and other influences. If you have a special request you can look up the resistance in our resistance list or contact our product management.
Temperature- and pressure range of application
UPVC is usable in a temperature range from 0°C up to 60°C. Temperatures higher than 60°C soften the material relatively fast. Under 0°C the impact-resistance decreases, therefore Akatherm FIP doesn’t recommend the use of UPVC in this range of temperature. Concerning the internal pressure capacity of tubes and patterns we refer to the graph under the section Pressure-Temperature-graph. For details regarding the maximum internal pressure capacity of accoutrements please note the additional comments regarding the accoutrement or make reference to our product management.
Electrical property
UPVC is a polar, amorphous thermoplastic with exceptional insulation properties. Because of the possibly resulting static electricity UPVC can’t be used in situations where a danger of inflammation or explosion exists.
Low weight
UPVC systems weigh only half in comparison to copper pipe installations and only 1/5 compared to steel pipe installations. This simplifies the handling and new fields of application are possible, in which UPVC can replace metallic systems because of its special characteristics.
As all thermoplastic plastics UPVC has a relatively high thermic coefficient of expansion (0,08 mm/m °C). This fact has to be taken into consideration during the planning of the tube system. There exist several possibilities: Installation of an expansion arc or compensators as well as clamping them at fixed points. In order to do this, sound knowledge of the use of plastic is necessary and we recommend to calculate the planned system with the help of a computer program.
Easy connection
UPVC tube components are connected to each other with adherence. The production of such glued joints requires expertise, which can be acquired in classes held by Akatherm FIP. Concerning the adherence please take into consideration the special guidelines from the adhesive supplier or the published instructions from the KRV (Kunststoffrohrverband e.V.) as well as the corresponding DVS-explanatory leaflets.

According to the U.S. Geological Survey, about 15% of Americans use well water in their homes. In each home, a well water system provides clean water at the turn of a faucet. Faulty or inadequate well systems can result in unsafe, unavailable, or slow-flowing water. For homeowners new to well water systems, well components may seem overly complicated. In this article, you can explore the key components of a well water system and how they work together to provide clean water for your home.

Components of a well water system
A home well water system consists of six main parts: well casing, well cover, water pump, pressure switch, pressure tank and water filtration system. These systems work together to deliver well water to each home as safe water for drinking, cooking, bathing and other uses as needed.
Well casing
The well casing is a tube that prevents the well mouth from collapsing. It is also sealed to prevent outside contaminants from entering your water supply. Well casings can be made of carbon steel, stainless steel, plastic or concrete. It allows the pump to maintain water access while protecting the well from foreign objects.
Well cover
A well cap as the name suggests is a cap located on the well casing. It protects well water supplies from debris, organic matter, pathogens and runoff. Well caps can be made from aluminum or plastic, and they have vents to equalize pressure on the inside and outside of the housing.
Pump
A well pump will move water from the well into the pressure tank. Depending on the type of pump used, it can be installed above the well or submerged in the well. The well pump above the water line uses suction to supply water to the system, while the submersible pump pushes water through the pipe to the tank. The size of the well will ultimately determine which type of pump is best for the particular well water system. For example, jet pumps and centrifugal pumps only work in shallow wells, while submersible pumps can be used in almost any type of well.
A well pump, pressure switch, and pressure tank all work together to supply water to the house. The pressure switch tells the pump when to turn on, and the pressure tank transmits pressure to the switch, allowing the switch to signal the pump. These communications allow the system to run efficiently with low power usage and increased longevity.
Well pressure switch
The well pressure switch detects pressure from the pressure tank to signal the pump when needed. The main purpose of the pressure switch is to maintain the life of the pump by helping it operate efficiently. During use, water flows out of the tank, causing the pressure to decrease until it reaches a preset level. When this threshold is reached, the pressure switch signals the pump to turn on. The pump will run until the tank reaches its maximum pressure threshold. At this time, the pressure switch will tell the pump to power off. This cycle allows the pump to run uninterrupted for a period of time calculated to keep the pump cool instead of every time the house needs water. A well-functioning pressure switch will significantly increase the life of your well pump.
Well pressure tank
The well pressure tank holds water until the water storage device in the house is opened. These tanks contain a pressurized bladder to maintain pressure as water enters and exits it. When the tank reaches the maximum capacity it can hold while maintaining pressure, called “depressurization,” the pressure will reach a critical point that tells the pressure switch to turn off the pump. When the tank has emptied to the preset point, the pressure switch detects the change in pressure and signals the pump to refill the tank. Therefore, the size of the indoor pressure tank must have sufficient draw volume to allow the pump to stay cool and not overheat due to start and stop cycles.
In well systems where water pressure is too low to pass through various filtration systems, homeowners may want to install a pressure tank upstream of the filter. Note that in this configuration, the life of the tank and other components may be shortened due to sediment, minerals, or other contaminants in the untreated water.

The filters and water treatment systems in well water systems make the water clear, delicious, and safe. Whole-house water filtration systems treat all water coming into the home from the well, while point-of-use filtration systems provide additional filtration to specific faucets, such as the kitchen sink. Well water requires at least some form of disinfection and sediment filtration. The most common water treatment systems in well water systems include UV disinfection systems, sediment filters, activated carbon filters, and reverse osmosis systems.
Disinfect well water
The most common form of well water disinfection is ultraviolet water disinfection. UV water purifiers expose water to ultraviolet rays as it flows through the system. The frequency of UV light in these systems is at a germicidal wavelength that inactivates microorganisms after a short exposure period. To ensure that UV light effectively inactivates microorganisms, a sediment filter must be installed between the water source and the UV system. If sediment enters a UV water purifier, it can block UV light from reaching all the water flowing through, causing bacteria, viruses and parasites to become active and capable of reproducing.
Additional well water treatment
Based on the contaminants present in the well water, an additional filtration system may be required. Reverse osmosis systems are a popular filtration solution for those who want to remove more contaminants from their kitchen sink. These systems remove practically all contaminants from the water except for bacteria that have been inactivated by the UV purifier. Other under-sink filters include KDF filters, activated carbon filters, and ultrafiltration systems.
Some wells may contain water hardening minerals calcium and magnesium. If present, these minerals must be removed with a water softener. Water softeners use salt water to exchange magnesium and calcium ions with sodium or potassium ions, removing hardness from the water. Water conditioners, also known as salt-free water softeners, should never be used on well water because they become ineffective when exposed to small amounts of iron or manganese.
Ways to choose a well water filtration system
Ultimately, the type of water filtration you choose for your well is determined by the contaminants in your well water. If you’re new to owning well water or are looking for a more thorough filtration system, start by testing your well water. For comprehensive testing, consult a laboratory listed on EPA’s list of certified laboratories. This facility has quality laboratories in each state, allowing homeowners from all over the country to quickly test their well water.
