What s the use of the pre filter installation order reversed

Pre-filter.

It is used for pre-filtration, to protect the post-filter and to make the post-filter more durable.

If the pre-filter is installed in the reverse order, it is equivalent to white installation, which not only does not play the role of filtration, but also does not play the role of protecting the post-filter.

It must be reassembled in order.

This needs to be chosen according to the situation of your own water quality.

If the tap water is seriously polluted, then it is best to choose to install a pre-filter, which can protect the reverse osmosis water purifier at home, and also save costs, because the water quality is too poor, then the filter element will be replaced more frequently.

BecausePre-filter. Troublesome installation and difficult to operate.

The pre-filter is the first level of tap water purification, the tap water is coarsely filtered, mainly to filter the large particles of tap water, sediment, rust, etc., these harmful substances are filtered after the water environment of the whole family has been improved, so whether the water purifier is installed or not, the pre-filter can improve the water quality, and the pre-filter can better improve the service life of the water purifier!

Function. Due to long-term use, the urban water supply pipe becomes relatively old, and there will be a lot of rust inside the pipe. Sediment.

and other impurities, because the pipeline is very long, so the water source flowing through will be polluted, the pre-filter accuracy is 5-100 m, which can filter out the impurities visible to the naked eye, such as: sediment, rust, etc., which can make the tap water return to the state when it left the factory, and better protect the faucets and showers at home!

Everyone should be familiar with limescale, the composition of limescale is mainly calcium and magnesium, and the scale of electrical appliances such as water heaters and boiling kettles is particularly serious, and the pre-filter can prevent calcium and magnesium ions and carbonate.

The ion combination prevents the generation of scale from the source, and can also form a nano-scale protective film on the inner wall of the water storage tank, which plays a role in repairing the rust of the inner wall of pipes and containers!

Generally, the primary processor commonly used in water purifiers is PP cotton.

It can filter the impurities of tap water, generally used in clothing, spray cotton and water purification equipment, the PP surface needs to be replaced frequently, and there is no backwashing function, the pre-filter has a backwashing function, which is more convenient to use!

Summary. Can the pre-filter be installed upside down, yes, but it is necessary to ensure that it is convenient to drain water during flushing and will not affect the use, and the filter must not be installed upside down, otherwise there is no way to discharge sewage. The installation location of the filter can only be determined after the installation of the pipeline water meter, and it is necessary to ensure that the sedimentary impurities generated in the pipe network will not endanger people's health.

Can the pre-filter be installed upside down, yes, but it is necessary to ensure that it is convenient to drain when flushing, and it will not affect the use, and the filter must not be installed upside down, otherwise there is no Luyin method to discharge sewage. The installation location of the filter can only be determined after the installation of the pipeline water meter, so as to ensure that the sedimentation impurities generated in the pipe network will not endanger people's health.

It can be installed upside down.

Is it convenient for you to send text here?

The pre-filter cannot be installed horizontally. The pre-filter is the first coarse filtration equipment for the whole house water, which can filter large particles such as sediment, rust, insect eggs, and bloodworms in tap water. The pre-filter is generally installed behind the water meter, and its main function is to restore the tap water to the standard before leaving the factory and protect the downstream equipment.

Dear, according to the information I have found, the principle of the pre-filter is very simple, which is to purify the water quality by filtering impurities, sediment, rust and other substances in the water. However, it is not recommended to install a pre-filter for the following reasons:1

The pre-filter will increase the water pressure loss and affect the flow rate of the water pair. 2.The pre-filter needs to be cleaned regularly, otherwise the purification effect will be affected; 3.The pre-filter can only filter large particles of impurities, and cannot purify microorganisms such as bacteria and viruses1.

The installation time of the pre-filter usually depends on the specific application and needs of the chain car. In some cases, pre-filters can be installed in the early stages of application development to ensure the security and reliability of the application. In other cases, pre-filters can be installed prior to application implementation to ensure the stability and performance of the application.

Whenever a pre-filter is installed, there are a few key factors that should be considered. First, the pre-filter must be integrated with the other components of the application and must work in tandem with the other components. Second, the pre-filter must be able to handle all the inputs and outputs of the application and filter and validate them as necessary.

Finally, the pre-filter must be able to protect the application from a variety of attacks, including cross-site scripting attacks, SQL injection attacks, and password guessing attacks.

To sum up, the installation time of the pre-filter should be in the early stages of the development of the application. At this stage, developers can design and implement pre-filters to ensure the security and reliability of the application. In addition, developers should also consider the performance and scalability of the pre-filter so that it can adapt to future needs and challenges.

Finally, the installation and configuration of the pre-filter should be done by professional security personnel and network engineers to ensure that it can effectively protect the application from various attacks.

<> "Do I have to install a pre-filter?"

First of all, let's talk about the function of the pre-filter, the main function of this thing is to filter large particles of sediment in the water, and there are some small red bugs, if you want to filter more finely, you can't do it, you can only install a water purifier. Some people may have questions, isn't it okay to install a water purifier directly, why install this pre-filter? In fact, the water purifier can only filter the water to drink, such as the water for bathing and washing the face, it cannot be filtered through the water purifier.

In addition, it can also play a role in protecting water equipment, such as toilets, water heaters, showers, faucets, which can effectively avoid the corrosion of debris in the water and prolong the service life.

The pre-filter must be installed, and how should it be purchased?

First of all, you don't have to choose too expensive, about 500 is already very good, two or three hundred socks can also be used, and then more expensive thousands, so that the fight is basically an IQ tax, the functional principle is the same, there is no need to buy too expensive.

Second, the pre-filter, to choose 316 medical grade, stainless steel filter, this material will not rust for a long time.

Third, the pre-filter, the flow rate of water is best to choose 4 to 5 tons, and the filtration accuracy is 40 microns, so that the water pressure will not be affected, and the filtration effect will be better.

Fourth, the material of the pre-filter cup must be explosion-proof, so as not to cause cracking and leakage in the later stage.

Fifth, the pre-filter, to choose with backwash function, this kind of filter scraper is with automatic rotation function. If you don't have this function, if you don't clean it for a long time, not only will it not have the effect of filtration, but it will also become a culture base for bacteria, so it is better not to install it.

On the whole, the pre-filter must be installed, but before the decoration, the owner will buy it himself, and ask the master to install it when the water and electricity construction is completed.

1) Public interest.

Installing a pre-filter naturally has many benefits for a family, but after all, living in a community, you must always take into account the feelings and interests of other residents when doing something.

The property does not allow the installation of pre-water filters, because this behavior will threaten the interests of the masses, first of all, it is a private invasion of some public areas, and only one installation will cause dissatisfaction among other families.

However, if the number of people installing is large, it will bring troubles such as water pipes that are easy to burst, so the property simply prohibits installation, which is also for everyone's benefit.

2) Interfering with maintenance.

There will always be times when something is damaged after a long time, and the same is true for the water pipes in the community.

When there is a problem with the pipeline, it is necessary to ask a professional to repair it, otherwise it is impossible to guarantee a normal life. But if a pre-water filter is installed inside the pipe, once there are other problems with the water pipe, the maintenance personnel are disturbed by the pre-water filter, which will greatly increase their troubles for repair.

To some extent, this is also an infringement on the interests of all residents, so in order to ensure that maintenance personnel can carry out normal operations in the event of a problem with the water pipe, the installation of a pre-filter will naturally not be allowed.

3) Giving rise to disputes.

After installing the pre-filter, firstly, the property will have to spend more time managing it, and secondly, if other owners accidentally cause some damage to the pre-filter, it is likely to cause a neighborhood dispute.

1. Who is responsible for the loss of leakage of public water pipes.

1) Because the water leakage problem caused by the public sewer pipe is not man-made, and it is still within the warranty period, the developer can be responsible for repairing, and the corresponding losses should also be borne by the developer. The shelf life of sewer pipes is usually 5 years, and any problems within 5 years must be managed and repaired by the developer.

2) If the warranty period has expired, causing water leakage, it has also caused the loss of furniture and household appliances in the owner's home. In this case, repairs can be made through the property management company, and the property management company is responsible for the damage. Especially in some formal communities, equipped with property companies, public facilities should be repaired, and if there is a problem, you can use the maintenance**.
