Seven problems of traditional non-negative pressure water supply mode

1. Serious pollution: tap water must be put into a pool or water tank first, which has poor sealing performance and is often polluted by sundries, stolen goods and even animal carcasses. It also produces scale and breeds bacteria, which seriously affects the health of users.

2. High investment: it is necessary to build a water pool or water tank, and the construction cost is high.

3. Large area: It is necessary to build a water pool or water tank, and the equipment occupies a large space, which will occupy a lot of commercial land and reduce the income.

4. High energy consumption: tap water must be put into the pool or water tank first, and then pressurized, resulting in zero pressure utilization rate of municipal pipe network, which seriously wastes energy.

5. Serious waste: most pools are civil structures, and water seepage and leakage often occur. Because of the serious pollution, regular cleaning needs to use a lot of water, which is a serious waste.

6. Complicated installation: due to the need to build water tanks or pools, the installation is complicated and the construction period is long.

7. High maintenance cost: maintenance work such as cleaning and disinfection needs to be carried out regularly, and the later cleaning and maintenance cost is high.
