Is it better to supply tap water from the top down or from the bottom up?

As the floors are getting higher and higher, the way the tap water is supplied has changed. It's not the kind of municipal tap water we're used to use to supply directly. Instead, the method of zoned pressurized water supply is adopted to supply water to the room.

So a friend asked: The current high-rise houses are all secondary water supply.

Is it? First of all, to give a personal opinion, that is, high-rise buildings basically have a secondary water supply.

Tap water supply method for high-rise buildings.

As the floor increases, the pressure required for the tap water to be transported upstairs is increasing. There is a general empirical data, that is, the pressure of 1 kilogram can reach a height of about 10 meters. Of course, there is no pressure loss here, only an estimate.

If it is a 100-meter house, which is about 30 floors high, the pressure required at this time may be 10 kilograms, which is the lowest value, and 12 kilograms are normally required. The high-rise water supply is divided into water supply zones according to such a procedure: generally speaking, the first to fourth floors are directly supplied with municipal tap water, and the pressure of water supply without passing through the pressurized pump room is basically megapascals, that is, 3 kilograms; Then it was roughly divided into a zone every 10 floors, and the water supply was supplied by pumps from each area.

This means that floors 5 to 15 are a partition, and floors 15 to 30 are a partition. And so on. If we live on floors 1 to 4, then the water supplied by the municipal tap water is not pressurized.

If it is made of five floors or more, it is basically through the pressurized pump room to supply water.

There are some problems with pressurized water supply.

Since the secondary pressurized water supply is sent to our room after the water pump in the water supply pump room in the community is pressurized. Under normal circumstances, each district is supplied with water by two pumps, one for the other for backup. Therefore, under normal circumstances, it is possible to meet the water supply requirements, but if it is a very long old community, it may be possible that two pumps will be damaged at the same time, resulting in the inability to supply water.

Another point is the pressurized water supply, which passes through the water pump house and then cannot deliver the water. The tap water is first stored in the tank of the pressurized pump room for a period of time. Inevitably, it caused secondary pollution of tap water.

Therefore, we must pay attention to whether the water tank in our community is regularly disinfected and tested for water quality.

The water pump room in my community has been used all the time, and it has never been disinfected and tested, so the water we may drink is of substandard quality.

Conclusion. Regarding whether the high-rise is all pressurized water supply, the personal opinion given is that the high-rise tap water is all pressurized water supply, except for one to four floors. Hope mine can be helpful to everyone!

If you have better opinions or suggestions, you can also share them for us to exchange and learn, thank you!

Any method of water supply is safe from the top down. For example, the water supply method of the 34-story small high-rise building in the community is to make a reservoir water tower at the top of the high-rise, and then there is an underground high-pressure pump to pump tap water into the water tower. Then there are water towers that provide piped water to the households.

Hello, tap water is naturally better from top to bottom, because the water does not go to a high place when it flows down. If the water is to go up constantly, it must be used, and other mobile water lists will drive the water to go up, and the water will flow down, just like the water in the river it will not go up, but will only flow down. There is no hindrance to the flow of water downstream.

In fact, there are no specific requirements for water delivery from the first time, after all, the current floor is very high, and the waterworks cannot be built to a very high place, so it relies on mechanized pressurization.
