For the tap water in our home, we all want it to be clean. But everyone will find that if the water is cut off in our house, after the water comes back, we turn on the faucet again, and the water will be very dirty. What does this show? In fact, the tap water in our home is indeed polluted. So what can we do to prevent these pollutants from entering our indoor water pipes at this time? In this article, the household miscellaneous world is here to answer the question of tap water pre-filter.

Is it necessary to install a pre-filter at home?

For the installation of the pre-filter, personal opinions are very useful. It can be said that even if we do not install a water purifier in our home, we just install a pre-filter, which can play a very good role. Many friends may think that the pre-filter is not very useful, but in fact, everyone still doesn't know much about the pre-filter. You can understand the following four points before making a decision.

①: The most essential function of the pre-filter is to filter out large particles such as silt and rust in the tap water. Because our tap water is supplied through the city's water supply pipe network, in the water supply pipe network, because the pipeline is too long, the service life of the pipeline is relatively long, especially some cast iron pipelines, which will cause a large amount of precipitated impurities. If these impurities enter our homes, they will still cause great harm to the human body. Therefore, the water quality must be filtered.

②: Some impurities generated in the pipeline, if they enter our indoor tap water pipeline, as the use time increases, they will adhere to the inner wall of the pipeline. As a result, the water flow of the tap water pipes in our homes is gradually becoming smaller and smaller, especially for some old-fashioned galvanized tap water pipes. As the service life increases, they may gradually become blocked inside. Therefore, it is also necessary to install a pre-filter for the pipeline in our home.

③: It has a good protective effect on indoor household appliances and water appliances. For example, we have a faucet, a water heater, a washing machine, a dishwasher, and a series of household appliances in our home, and these household appliances have relatively high water quality requirements. For example, we take a common storage-type electric water heater as an example. If the water quality is particularly poor, then it doesn't take long for our storage-type electric water heater to find that the water flow becomes smaller and smaller. If it takes a long time, it may cause no water. In fact, this is also the result of serious fouling of our electric water heaters caused by impurities.

④: It will also cause damage to some water facilities in our home. Because the urban water supply network has a relatively long service life, rust in the pipeline will cause the water to change color. The simplest point is that if these sand or rust enters our faucet, it may cause our faucet to be slowly damaged. If the faucet can't be turned off, dripping water, in fact, the most important reason is the dripping caused by the wear of the internal ceramic diaphragm caused by these rust impurities.

What are the effects of installing a pre-filter at home?

In addition to purifying the tap water in our home with a water purifier, there is actually a very important treatment step, which is filtration. Because the water purifier handles some finer particles. But if the quality of our tap water is extremely dirty, and there are some relatively large microbial particles, it will cause our water purifier to quickly need to replace the filter element. Therefore, the water at home is relatively dirty, and the most common method we use at this time is to install a pre-filter.

①: The overall function of the pre-filter. Because of the pre-filter, it has two characters, so it is installed at the forefront of our tap water. It can be said that the pre-filter is also the first line of defense for all our indoor water, and it is the first coarse filtration equipment. The pre-filter can generally filter out large particles such as silt and rust in the tap water. This avoids poor water quality in our home.

②: Installation location. Like the pre-filter, it is generally installed at the front end of the water pipe. Like the current buildings, the tap water in our home is received from the plumbing wells in the outdoor walkways to our interiors. We opened the plumbing well and found the water meter in our house. Behind the water meter is a tap water pipe that enters our room. At this time, a pre-filter can be installed on the tap water pipe behind the meter to ensure that the tap water entering our room is filtered.

③: Actually, the pre-filter is a reliable impurity filtering device. And the location where it filters is the entry point of the tap water in our home. Like the common pre-filter on the market at present, it can filter out some particles of impurities above 45μm, and then the water quality can be restored to the standard of the tap water factory. In other words, it is basically possible to filter out some impurities that appear in the pipe network.

How to choose a pre-filter for household tap water?

In fact, the tap water pre-filter is not very complicated, so there are many pre-filters on the market now. However, one of the core of the pre-filter is the filter, which is directly related to the degree of filtration. So when you choose a pre-filter, you also need to pay attention to the selection skills. For this, I personally recommend the following selection suggestions to everyone.

①: The pre-filter must be selected with automatic flushing function. The material of the filter element can be reused and is not disposable. That is to say, when we buy the pre-filter, everyone should pay attention to not replacing the filter element. Because it is very troublesome to replace the filter element, we may not need it after a few years of use. And if you choose automatic flushing, it's very good. The key here is to observe whether it can be rinsed thoroughly and whether it is convenient to rinse. Avoid secondary pollution caused by the installed pre-filter.

②: When purchasing a pre-filter, we have to look at the level of filtration accuracy. It can be said that the filtering precision of the pre-filter is getting higher and higher at this stage, and some particularly tiny particles can also be filtered out and rinsed. But everyone should be aware that the pre-filter is only a preliminary filtration of water, and it is impossible to achieve a good water treatment effect. Therefore, we only need to choose the appropriate processing accuracy, instead of choosing the particularly high-precision filter, which would waste the filter element.

③: When we choose the pre-filter, we also need to consider the price. Let’s go to the market to take a look. The pre-filters currently on the market range from tens of dollars to hundreds of dollars, and then to thousands of dollars. This mainly depends on the brand and the quality, as well as the function of the pre-filter and so on. I personally think that tens of dollars is definitely not usable, generally a few hundred dollars, better ones, it does cost thousands of dollars. When you buy, you can compare them more.

Concluding remarks

As for the pre-filter, I personally think it is necessary to install it. Because it can treat some pollutants in the water to make it reach the factory standard of tap water. The tap water has corresponding inspection standards when it leaves the factory, but after it is transported through a large number of pipe networks, or other reasons may cause pollution, it is recommended that you install a pre-filter. But the pre-filter is not a water purifier, so everyone must distinguish clearly. In addition, when we purchase and install, we must consider the convenience of our future washing. After installation, it is never impossible to wash or replace the filter element. In fact, this will become the source of secondary pollution of the tap water in our home. It is better not to install it.
