Water Pipe Deterioration

As the building age increases, dirt and slime can accumulate inside the water supply pipe. Unlike the water tank or the drainage pipe, the water supply pipe is not cleaned nor inspected on a regular basis.


Transition of Water Pipe Material

Deterioration condition varies greatly on the water pipe material.

Blade Hose Deterioration

The emission of green//white/transparent matter is a common faucet problem. Deterioration of “thermoplastic elastomer”, the rubber used for the faucet blade hose, is the main factor for such problems.

Faucet Failure

Generally, the service life of a faucet is 10 years.
Deterioration symptoms: Water leakage, water volume decrease, etc.

Other Types of Deterioration of Water Supply Equipment

Besides general equipment, there are problems such as water pressure abnormality caused by deterioration due to external corrosion, pump malfunction, malfunction of pressure reducing valve, etc.

Advances in materials make life prolongation unnecessary, and in recent years, more condominiums choose “to replace” or “to clean” as a means of water supply facilities maintenance.
