啊？There are so many people who don't know about the secondary water supply?

What about secondary water supply？A lot of people don't know yet。

If we live in a high-rise residence, when we open the faucet at home every day, the water flowing from the faucet is actually not directly supplied by the water company, but the water in the reservoir at the top of the building is pressurized by the secondary water supply equipment of the community before being sent to each of our households。

Q1

There's secondary water supply a few floors up？

Where the municipal water pressure cannot be delivered, it must be pressurized twice, that is, the secondary water supply。

Generally speaking, the municipal direct water supply is used below 4-6 layers, and the above parts have to use automatic secondary water supply equipment。

However, there are also direct use of pressurizing equipment from the first floor, depending on the local municipal pressure is how much, the water supply pressure of the water company can only reach about the 6th floor in accordance with relevant regulations, far from meeting the needs of the high-rise。

Q2

Possible hazards of secondary water supply

When the tap water is transported in the pipeline, the internal environment is relatively sealed。However, the tap water in the home is not directly supplied by the water company, but through the secondary water supply equipment of the community, the water set in the reservoir on the top of the building can be used after pressure。

If the secondary water supply management is not good, it will increase water pollution。For example, if the reservoir of the community is not cleaned and disinfected for a long time, or it is not covered and locked, it may lead to rainwater and foreign bodies entering the pool, thus breeding bacteria。

How to prevent secondary water supply pollution？

In addition to the need for special management of water tanks and other needs, daily cleaning, we consumers can also reduce the secondary pollution of tap water by installing some household water purification equipment。

For example, you can install Shijian Mingche reverse osmosis water purifier，The first stage of filtration is the ultra conventional configuration of hollow fiber ultrafiltration membrane，RO reverse osmosis membrane final purification filter pure good water，Supplemented by double filter flushing function，Always restore the new machine status，Rated total net water up to 15,000L，Is 3 times the ordinary water purifier，Truly achieve ultra-long filter life，Save money。

Secondary water supply pollution is also qualified tap water, but the state is still advocating the main reason for water purifiers, details click the blue character to see:Tap water qualified, why the state also advocates water purifiers？Read it and you'll understand!
