Water damage accounts for the largest type of damage among insurers. Water leakage often occurs in Norwegian homes, and can cause damage to surfaces and building structures. This can cause the removal of the wall and floor, and it can have major financial consequences for the family affected. Not all insurance policies cover all types of water damage, despite it costing water damage insurers around 1 billion a year.
In a meeting between Pavels Innovation, Grepi Plast and Armaturjonsson, it was discussed how to prevent the water damage. The innovative solution was Arjonstop.
In 2016, the development of Arjonstop began. We were through the whole process from prototyping to completion and production of the finished product. Pavels Innovation assisted Armaturjonsson with product development and prototyping. The form tools for the plastic components were developed by Grepi Plast in cooperation with manufacturers in China. Grepi's own tool constructor in Shenzhen was central to the development and production of the design tools. It takes 18 more tools to produce all the plastic parts in Arjonstop.
In the development of Arjonstop we have used plastic in all parts that are in contact with water and in the valve housing. Plastic has never been used as the only material in water stop valves before. This is an important new direction, since you want to get away from brass in drinking water systems. The only parts that are not in plastic are motor, gear, electronics, couplings and pressure transducer (which measures if there is pressure loss on the downstream side). In the center of the valve there is a large ball, which opens or closes the water flow. This is cast in PPSU (polyphenyl sulfone), which is very hard and has high dimension stability. Standard pipe connections are made of wood-quarter stainless steel, which is mounted in the valve using advanced induction stenology.
Grepi is also responsible for pressure testing, packing and further distribution of Arjonstop. As part of the valve safety procedure, a function test and pressure test are carried out at 10 bar before leaving the factory. Serial production of the water stop valve is now well underway at Grepi Plast.
A new efficient water stop system that protects your home from water damage. Arjonstop is easier to detect water leaks and avoid expensive water damage.
If detectors placed around the house notice water leakage, it will send signals to Arjonstop that will turn the ball around, so that water cannot flow through This will then cause the water leak to be stopped before major damage is incurred.
It performs a self-test once a day to check that it will detect any water leakage. The valve is an engine-controlled cool valve, which goes to be the most robust on the market. Arjonstop is operated by the mains, but has one need battery that ensures that the water system is in operation even in case of shorter power outages.
The finished system includes: the water stop valve itself with control electronics, engine and gear, control unit, wireless sensors that can be connected to sensor cables, and a wireless switch for shutting down otherwise. Two editions have been made: Arjonstop Basic and Arjonstop Connect, the latter communicating with Arjonstop's smart house management app.
