Life on earth originates from water. Indeed a large portion of our own body mass is composed of water. Are we taking our water quality for granted when we use it for washing, bathing, cooking? What have we done to ensure its cleanliness?

The Hong Kong Water Supplies Department (WSD) recommends that all water storage tanks in the building should be cleaned and sanitized at least once every three months or as often as necessary.
(WSD water supply system maintenance guide – Clause 2.)
While we can safely assume that is already being done by your building property management, the 'last mile' – the water supply conduit that provides water into your unit - is often neglected. Think of it as drinking a fresh glass of juice with a dirty straw reused over the past 15 years!

Pipes age like everything else. Metallic pipes oxidize and become rusty over time. The L-shape pipes (commonly found in junctions or joints) can accumulate rust, deposits from corrosion or simply water sediments over a prolonged period of time. This kind of deposits accumulates and thickens like cholesterol in the arteries, only that they become the hot bed for bacteria breeding. In the long run, this clotting may even cause premature pipe hardening and cracking. All this can now be avoided.
Oxidization deposits and heavy metals can enter and remain in our body for a long period of time. Scientific studies have confirmed such effect and their relation to causing slowed growth in infants and children, Alzheimer’s diseases, kidney and liver problems or even cancer.

Pipe deposit or lining can help breed harmful substances such as fungi and algae, backwoods coli and legionella


You lavish thousands on skincare products but let your face expose to your untreated tap water everyday?
Invest time to seek out fresh organic produce but largely neglect the basic element – water – that
keep us alive?
Spend time and money on fitness program, health insurance and body check but take for granted
the water quality you and your family depends upon every day?
Your building property management scrub and sanitize your building water storage tank every three months,
it's time to clean you own pipes to get the quality water it was meant to be supplied. Act now and contact us.

What is eco-washer system?

The eco-washer system is a microprocessor-controlled cleaning apparatus invented in Japan. The technologies behind this machine receive multiple patents from half-a-dozen countries.

What does it do?

Through the use of carefully controlled amount of water and air, the pressurized water-and-air combination provides thrust to weaken the deposit and clotting, peel them off the pipe while purging them out of your home pipe system.

How is this achieved?

Besides the use of pressurized air and water, the microprocessor controls various programs during the course of cleaning:

Direct thrust
Direct pressure and hi-speed hammering rusty clots and sediment lining
Bi-directional thrust
Loosening and clearing clotting and deposit with forward and backward thrusts
Swirl program
More effective with reaching angular and / or hidden hard-to-reach areas
High-frequency pulsation program
High-pressure air bubble creating effective scrubbing action against pipe lining


The above programs are interchangeably deployed to ensure thorough cleaning. The result is visible and more often than not, startling!

Is it safe?

The microprocessor constantly monitors the pressure within the pipe system during the entire cleaning process. There will not be excessive pressure that causes damage to the pipe system. KA service teams are well trained on the apparatus and are experienced in general plumbing – whether it is residential building, commercial establishments such as coffee shops or restaurants.

Out pledge to Mother Earth

The entire cleaning process is free from any chemical or cleaning agents. It is eco-friendly and does not require any additional ‘rinsing’ or cleaning after the job is completed.

How long does it take?

The entire set up, cleaning and test result will take approximately two to three hours depending on the condition, number of taps outlets and pipe routing within the premise.
