In home life, more and more people have begun to pay attention to water quality safety.
Due to the frequent use of water sources, if we cannot guarantee the health of the water quality, it will pose a threat to our health.
Many people don't understand, when decorating, they are accustomed to install a pre-filter, which can be quickly filtered to ensure the safety of water.
I just don't know if you have noticed, there are many people who do not recommend installing pre-filters, why is this?
What is a pre-filter?
A pre-filter, as the name suggests, is a type of filtration device that is installed at the front end of a water supply pipe.
It is mainly used to filter impurities and particulate matter in tap water to protect downstream water equipment and improve water quality.
A pre-filter usually consists of a tank and an internal filter element. The filter element can be a screen, filter element or other filter material, and its pore size can be selected according to the need, generally between tens of microns and hundreds of microns.
As the water passes through the pre-filter, impurities and particulate matter are trapped on the filter element, while the filtered water passes through without a hitch.
The role of the pre-filter
(1) Protection of downstream equipment:
The pre-filter can effectively remove large particles in the water, such as sediment, rust, etc., to prevent them from causing damage to downstream water purifiers, water heaters, washing machines and other equipment, and prolong the service life of the equipment.
(2) Improve water quality:
By filtering out suspended solids and impurities in the water, pre-filters can improve water quality, making the water clearer, cleaner, and healthier to use.
(3) Reduce scale and rust:
Substances such as calcium and magnesium ions in water are prone to form scale during the heating process, and the pre-filter can reduce the content of these substances, thereby reducing the generation of scale. At the same time, it prevents corrosion of pipes and equipment and protects the normal operation of the system.
Why is it not recommended to install a "pre-filter"?
1. Cause water pollution
In some cases, the pre-filter may cause secondary contamination of the water source.
While it was originally intended to filter impurities from the water, problems can arise if the filter is not cleaned or replaced frequently.
For example, when the whole family consumes a lot of water, the filter cartridge will accumulate a large amount of impurities and bacteria in a short period of time.
These tiny organisms may be few in small numbers in the flowing water and do not produce odors, but once they adhere to the filter, they can form a foul-smelling buildup. This is a fact that I have experienced firsthand.
The purpose of the filter is to capture impurities in the water, but if it is not cleaned up in time, it can become a breeding ground for bacteria. These bacteria can multiply on the filter and re-enter the water source with the water flow, resulting in secondary contamination.
2. It is easy to cause pipe bursting
The installation of a pre-filter in a pipe well may cause a burst problem.
When a filter accumulates a certain amount of dirt and wastewater, it can cause additional pressure on the pipes if it is not cleaned and discharged in a timely manner. Over time, this pressure can cause pipes to burst, causing bursts.
Once a pipe bursts, water will gush out quickly, which will not only cause overflow on the floor, but also cause serious damage to public facilities such as elevators and stairwells. The infestation of water may affect the normal operation of the elevator, cause a short circuit in the electrical equipment, or even paralyze the elevator. Stairwells can also be soaked with water, which can damage the floor, walls, handrails, etc.
3. Affect water pressure
The pre-filter is installed at the inlet end and can really have an impact on the pressure of the tap water in your home.
In my family, for example, we live on the 8th floor, and the pressure from the water is not very high. After installing the pre-filter, the water pressure became significantly lower.
This change in water pressure is especially noticeable in the shower. The pressure of the water outlet of the shower head at home has become very small, and the impact of the water flow is not felt at all when taking a shower. It can only make the shower head droop naturally, and the water flows down slowly, which is a very uncomfortable shower experience.
In addition to showers, other water appliances may also be affected. For example, equipment such as washing machines and dishwashers that require a certain amount of water pressure to work properly may affect their cleaning results due to insufficient water pressure.
The amount of water coming out of the tap may also be reduced, causing inconvenience to daily water use.
Write at the end:
No wonder it is not recommended that you install a pre-filter, it has certain drawbacks, do you think the pre-filter is easy to use?
