Property purifier

Nowadays, in order to purify domestic water, many friends will install purifiers, which can filter out impurities in water and make drinking healthier. When installing the water purifier, it is very dangerous not to install the front water purifier. Even if installed, it can only be installed in the kitchen. At present, a lot of domestic water is not recommended for direct drinking, and it is filtered before drinking. Generally, people will install a water purifier in the kitchen, which can filter out impurities in domestic water and ensure drinking safety. Some friends also installed pre-filters. This kind of water purifier is not recommended for everyone to install, because it has many shortcomings and is very dangerous. Why not install it?

One: Why can't a pre-filter be installed here?

1. Infringement of public areas

If the pre-filter is to be installed, it must be installed in the owner's public pipeline well. As we all know, the public pipeline wells belong to all owners. If someone installs the front filter privately, it will infringe on the rights and interests of other car owners.

2. It is easy to cause accidents

If the pre-filter is installed in the pipeline well, it is likely to cause the water pipe to burst when the filter works. Not only will the floors in the community overflow seriously, but also some public facilities will be damaged.

3. Maintenance difficulties

When installing water pipes in pipeline wells, the reserved space shall be strictly calculated. If the owner installs the pre-filter privately, it will occupy these reserved spaces, and it will be difficult to maintain the pipeline when there is a problem. Moreover, if the water filter is damaged during maintenance, it will also cause disputes between owners.

Two: What are the styles of pre-filters?

1. According to different working properties, the pre-filter can be divided into downstream filter, laminated filter, siphon filter, backwash filter and floor heating pre-filter. So many filters have different functions. The pre-filter that is more suitable for home use is the reverse water filter.

How to choose the front filter?

2. When the filter needs to flush the trapped residue, it will adjust the filter manually or automatically. The filter itself has a reversing multi-way valve to realize the reverse turn of water flow to the east, and the original water flow will flow in from the side flow direction of the filter screen to achieve the purpose of reverse flushing.

3. Compared with other washed aquatic products, the washing design of backwashing filter is more reasonable, and it can be washed directly and backwashed. The impurities in the water can be completely washed out, and the accumulation of impurities can be controlled, resulting in secondary pollution.

Three: How to choose the front filter?

1. Look at the material of the pre-filter when selecting the pre-filter. Generally, the water pressure of this pre-filter is relatively high. The selected materials must be good, such as copper and stainless steel, and some cheaper ppc.

2. The pre-filter screen we installed is made of copper, which is durable, rust-free, mildew-proof and corrosion-proof. It will not break after a long time of use. Stainless steel is relatively cheap, and some problems will occur after a long time of use.

After reading this article, friends all know the disadvantages of installing a pre-filter screen. Installing this water purifier not only makes others feel troublesome, but also prone to dangerous situations. Therefore, many residential properties now do not allow everyone to install pre-filter screens, which is troublesome to install and maintain and easy to cause injuries. If we want to install the pre-filter, we can install it in the kitchen.
