Since the leasing plan is designed for all residents within a community, and the system is installed at the main water tank, approval from the community management committee is required for installation. If you are interested in this plan, you can provide us with the contact details of the management committee, and we will send a specialist to discuss the leasing plan with them.

Q4：Can individual apartment or townhouse residents apply for the whole-house water purification system？

Yes, you can. You can inquire through our Facebook fan page, official LINE account, or by calling our service hotline. We will provide a free on-site inspection and equipment selection advice to offer you the best water purification solution.

Q5： If I already have an under-sink water purification system, do I still need a whole-house system？

An under-sink system only filters water from a single outlet, so other water sources in the home do not get purified. To ensure that all water sources in your home are clean and free of contaminants, we recommend installing a whole-house water purification system. This also helps extend the lifespan of water-related appliances and prevents exposure to contaminants such as insect eggs or other impurities.

Yes, many new developments are installing whole-house water purification systems to enhance the value and appeal of their properties. You can refer to our leasing plan introduction at https://www.chuanchiu.com.tw/article.php?lang=tw&tb=3&ot=all or contact us for more details.

After water is treated by a municipal water plant, chlorine is added to disinfect the water and prevent bacterial growth in the pipes. This results in residual chlorine, which can cause dry hair, skin allergies, and long-term health issues such as cancer and heart disease. Untreated water may also contain heavy metals or impurities. Therefore, installing a whole-house water purification system ensures safe and clean water for daily use.

Q1：Why is it necessary to clean pipes？
Over time, pipes can accumulate dirt and foster the growth of bacteria such as E. coli, Legionella, enteric viruses, and microcystins. They can also collect harmful heavy metals like arsenic, lead, chromium, and mercury, leading to serious issues like rusty water, pipe blockage, and reduced water flow.

Q2：Do different types of pipes require cleaning？
All types of pipes can accumulate deposits. Here’s the typical water discoloration associated with different materials:
• Plastic Pipes: Milky, light green, or light yellow (accumulated bacteria and algae)
• Iron Pipes: Rusty red or brown (iron rust)
• Stainless Steel Pipes: Milky and sticky with algae and bacteria
• Using Groundwater: Black water

Q3：How can you identify impurities from the color of the flushed water？
• Rusty Red or Brown: Iron rust
• Milky Color: Bacterial colonies
• Juice-like Color: Iron rust and bacterial colonies
• Green: Algae or algal toxins
• Herbal Medicine Color: Heavy metals
• Black: Contains all of the above

Q4：What principle is used in pipe cleaning？
The process utilizes citric acid to dissolve scale and grease. At a temperature of 50 degrees Celsius, citric acid quickly dissolves scale. A microcomputer controls pneumatic insertion into the pipes, creating various effects such as water hammering, rapid backwashing, spiral side washing, and high-frequency vibrations. These actions clean the pipe walls and flush out citric acid and dirt.

Q5：What are the benefits of high-frequency cleaning methods？
They are cost-effective, noiseless, quick, and safe. Since no chemical solvents are used, it is the most natural method.

Q6：Which household water lines can be cleaned using high-frequency methods?
Generally, all household water lines can be cleaned, including: cold and hot water pipes for bathroom sinks, showerheads, kitchen sinks, and washing machines.

Q7：How long does the cleaning process take?
For a standard single-family home, it usually takes about 1.5 to 2 hours; for a detached house, approximately 2 to 4 hours.

Q8：If the water company filters the water source, why is there still so much dirt in the pipes and water tanks?
Contamination can occur throughout the entire water supply chain. Sources of contamination include:
1. Upstream Catchment Areas: Pesticides and chemical fertilizers
2. Disinfection with Chlorine: Large amounts used to kill bacteria
3. Aging and Damaged Pipes: Old or broken pipes can let in sediment and heavy metals
4. Storage Tanks: Contaminated by rainwater, cockroaches, ants, and other small animals
5. Water Tower Covers: Tiny gaps allow airborne pollutants and dust to enter

Q9：Can pipes older than 20 years be cleaned?
The risk of pipe rupture increases with age. It is best to have a professional assess whether the pipes can withstand the cleaning pressure.
