Launch of Water Leakage Interception and Damage Reduction Device for Residential Use
STAGEA LLC has launched "Water Leakage Interception and Damage Reduction Device <STAGEA W10>," designed to prevent water supply pipe leakage accidents in condominiums and apartments. This device automatically detects leaks and stops the water supply to mitigate damage, contributing to countermeasures against pinhole leaks in old hot water copper pipes and preventing pipe damage during earthquakes.

Our company (STAGEA LLC) has recently launched "Water Leakage Interception and Damage Reduction Device ", a device primarily for condominiums and apartments, designed to prevent water supply pipe leakage accidents.
This device performs an automatic diagnosis when it detects water leakage, and if it determines that there is a leak, it immediately stops the water supply, thereby preventing leakage accidents.
It primarily focuses on countermeasures against pinhole leaks that frequently occur in copper pipes widely used for hot water supply, and also implements measures against leakage accidents caused by the bursting (damage) of water supply pipes under certain conditions.
In recent years, water leakage accidents have been frequent in condominiums and apartments.
The most common cause of water leakage accidents is said to be pinhole leaks in hot water copper pipes, which rapidly spread from the mid-1970s to around 1998.
Copper hot water pipes became widely adopted because of their strong rust resistance and ease of installation.
However, because they are very soft, they are gradually eroded by air bubbles contained in hot water and the flow of the hot water itself. After about 30 years of installation, tiny holes (pinhole leaks) can appear due to complications with other factors of deterioration such as electrolytic corrosion.
Water leakage accidents due to this cause have become particularly noticeable since 2015.
When a water leakage accident occurs, it causes significant damage to interior materials and household goods on the floor below. The responsibility for a leakage accident occurring inside the building structure (within the exclusive use area) is borne by the exclusive use right holder, etc., unless otherwise stipulated in the management regulations.
Many people become anxious upon hearing about water leakage accidents in their neighborhood and consider predictive maintenance (proactive replacement before an accident occurs). However, many of these involve dismantling walls and floors, and construction costs often exceed 1 million yen, making solutions not easy.
Furthermore, the fact that many of those who purchased such new homes are now pensioners makes resolution even more difficult.
Even with sufficient financial resources, there is significant psychological resistance to undertaking large-scale construction solely for pipe replacement. Many people would prefer to avoid incomplete expenses by combining full renovation or water area renewal (replacement of system bath units, system kitchens, etc.) with pipe renewal if possible, waiting until they have sufficient funds.
On the other hand, if the leakage occurs inside the building structure (parts buried in concrete walls or slabs and inside pipe shafts), the management association bears the responsibility for compensation.
Even if there is no direct burden on individual exclusive use right holders, if repair reserve funds are used for compensation or temporary collections are necessary, all exclusive use right holders will suffer disadvantages.
This can also further move away from sound maintenance and management, triggering a vicious cycle from which it is impossible to escape.
Many of these accidents are covered by personal liability insurance for exclusive use right holders, facility liability insurance (if the exclusive use right holder is renting out the property), and comprehensive condominium insurance (if an optional contract is in place). However, as water leakage accidents in older buildings are increasingly heard, a certain degree of foreseeability is evaluated (evaluated as intentional or gross negligence).
This can lead to situations where full compensation is not provided, or renewal of comprehensive condominium insurance is denied in the following year due to an insurance claim.
Even if insurance is successfully applied and compensation liability is fulfilled, the restoration of the exclusive use area where the water leakage accident occurred is at the self-expense of the exclusive use right holder.
Unless work such as installing underfloor ventilation or completely removing and rebuilding the interior is carried out, water may remain under the floor for a long period, or high humidity conditions may continue, leading to mold growth and health damage.
The "Water Leakage Interception and Damage Reduction Device " mitigates these risks.
Main Features
Automatically diagnoses upon detecting water leakage.
If a pipe problem is determined, the water supply is stopped to prevent further damage.
Mainly for hot water copper pipes, but can also be used for leakage prevention due to bursting (damage) of water supply pipes under certain restrictions.
Earthquake-sensing automatic diagnostic function
Automatically diagnoses when an earthquake exceeding seismic intensity 4 to weak 5 is detected.
This function is mainly for metal pipes (metal water supply pipes).
Although water supply pipes are relatively less likely to cause leakage accidents, if an external force strong enough to deform the building is applied, they may break (snap) and leak out explosively.
A large volume of water outflow is difficult to distinguish from household use, and if water is stopped due to a false detection, it can impose a significant burden depending on the timing (e.g., during bathing).
Therefore, as one of the countermeasures focused on water supply pipe damage causes, we have implemented a function that performs automatic diagnosis when an earthquake is detected.
Long-term absence water supply restriction function
If water supply occurs when a resident is away for 1 to 3 days or more, water pressure restriction, water supply time restriction, or water supply stoppage will be implemented depending on the number of days.
This, in conjunction with the earthquake-sensing automatic diagnostic function, aims to protect homes.
