Services by Property Type
The concerns and points requiring special consideration for plumbing systems differ depending on the type of property. We tailor our response to each property’s characteristics, including consideration for residents, tenants’ business hours, and grease-control measures specific to restaurant tenants.
For Customers Managing Apartment Buildings

In apartment buildings, graywater drainage pipe cleaning and drinking water storage tank cleaning are generally carried out about once a year. In the case of a Building Water Tank System that uses only water supplied by a waterworks utility as its source and has a receiving water tank or other tank with an effective capacity exceeding 10 m³, Japan’s Waterworks Law requires cleaning at least once a year and a Building Water Tank System Inspection at least once a year. As buildings age, pipes, pumps, and water storage tanks also deteriorate, so regular cleaning and inspections help identify abnormalities early.
- When entering private units for graywater drainage pipe cleaning, we provide careful support, including protective covering and cleaning after the work.
- We prepare notices for residents.
- If you are concerned about aging water supply and drainage pipes, pumps, water storage tanks, and other equipment, we propose renovation plans as needed based on inspection results.
- For buildings more than 30 years old with symptoms such as red water or pipe blockage, please also consider the “NMR Pipetector®”.

For Customers Managing Buildings
(Office Buildings, Commercial Buildings, etc.)

In office buildings and commercial buildings, drinking water storage tank cleaning and water supply system inspections are generally carried out about once a year. Where there is a water storage tank with an effective capacity exceeding 10 m³, Japan’s Waterworks Law requires cleaning at least once a year and a Building Water Tank System Inspection once a year. In buildings with basement floors or underground parking areas, regular cleaning of drainage tanks is also necessary. Adjusting work hours and work processes so as not to interfere with tenants’ business operations is an important point.
- We take tenants’ business hours into consideration and adjust work hours and work processes accordingly.
- For equipment such as water supply pumps and water storage tanks that can affect the entire building in the event of a sudden failure, we check their condition through inspection and cleaning, and propose renovation work as needed.
- We also handle inspections and renovation work for equipment other than plumbing systems, such as fire safety equipment, electrical equipment, and air-conditioning equipment.

For Customers Managing Properties with Restaurant Tenants

In properties with restaurant tenants, grease and food residue accumulate quickly, and depending on the type of restaurant, it is common for grease trap cleaning by a service provider to be carried out about once a month to once every several months. Drainpipes are also prone to oil blockages, and cleaning once or twice a year is recommended. If there is a kitchen or drainage tank in a basement level, drainage tank cleaning is also necessary. Because leaving blockages and odors unresolved directly affects tenant operations, higher-frequency maintenance than ordinary properties is an important point.
- We carry out planned cleaning of grease traps, drainage tanks, and other equipment according to the conditions of each property.
- For oil blockages and odors in drainpipes, we check the accumulated dirt and clean the pipes using an appropriate method.
- To prevent restaurant drainage problems from affecting upper floors or other areas, we identify abnormalities early through inspections of drainpipes and drainage pumps, and propose renovation work as needed.

Red Rust Prevention and Rehabilitation Device: NMR Pipetector®

Before replacing pipes,
consider an anti-corrosion device!!
- Installed in more than 4,400 buildings in Japan and overseas
- Extends the service life of water supply pipes by more than 40 years*
- Cost is one-fifth to one-tenth of pipe replacement
(for apartment building water supply pipes)* - Anti-corrosion device that uses no electricity
*Based on manufacturer-published materials. Effects and costs vary depending on the condition of the pipes and building conditions.
Water supply pipes used in many buildings, such as large commercial facilities, apartment buildings, hospitals, and hotels, may develop red water, pipe blockages, leaks, and other problems caused by red rust after more than 30 years from construction. To ensure residents can live with peace of mind and to maintain the value of the building itself, prompt piping renovation work becomes necessary.
This is why we recommend considering NMR Pipetector® before pipe replacement.

Mechanism and Effects of NMR Pipetector®
By discharging the free electrons (hydrated electrons) in the water itself flowing through the pipes, red rust is changed into water-insoluble black rust, significantly suppressing deterioration from inside the pipes. Black rust has the property of forming a dense film on the iron surface and preventing iron from corroding, and it has been used since ancient times in Nambu iron kettles and Chinese woks. Also, because it has a smaller volume than red rust, it can also be expected to help suppress blockages inside the pipes.
