How should the pre filter be maintained?

1. Turn on the knob switch at the bottom of the pre-filter, the pressure of tap water will flow out from the sewage outlet at the lower mouth, and under the action of pressure, it will bring out the particles and slag intercepted inside; The valve can be opened and closed several times in the middle of the process to allow the water to form a brief and rapid impact and speed up the discharge of sediment.

2. Hold the transparent part of the pre-filter with your hand, rotate the wiper blade, let the wiper move back and forth inside the filter, under the force of the pressure impact of the scraper and tap water, the sediment adsorbed on the filter screen will fall off at an accelerated pace and be discharged from the sewage outlet.

3. Close the main water inlet valve, rotate the transparent part of the pre-filter by hand, so that the filter screen, scraper, and transparent cover are completely separated, and then wash the three accessories repeatedly with clean water until the sediment adsorbed on the top is all clean, and then reassemble them in turn.

The cleaning steps for the pre-filter are as follows:

Tools: pre-filter, blowdown valve, clean water, ball valve, master valve wrench, filter element, dish soap, rag,

1. First of all, we have to observe for 1 2 weeks to see if there are impurities in the filter bottle of the pre-filter, if there are impurities, we need to open the sewage valve for flushing first.

2. After the sewage valve is flushed, a group of books before sewage discharge must check whether the sewage outlet is tightly connected with the drainage pipe, if the connection is not tight, we will connect it tightly and then re-clean the sewage once.

3. Rotate the ball valve at the end of the filter down to 90 degrees, and then open the sewage outlet for sewage discharge.

4. The time of sewage discharge should be determined according to the number of impurities, if there are more impurities, the time for our sewage discharge is longer, and if the impurities are relatively small, the general control can be completed in about 20 seconds. After the blowdown was done, we rotated the black ball valve up to 90 degrees.

5. After closing the main valve, the water in the filter bottle of the front filter is discharged again, use a wrench to unscrew the filter bottle and then unscrew the filter element, clean it with water mixed with neutral dish soap, ensure that the dish soap is cleaned, and finally install the pre-filter back, before installing it back, be sure to wipe the filter dry.

At present, the pre-filters on the market are non-disassembled, washed, and replaced.

Generally, it comes with a flushing and cleaning function, and only needs to be discharged regularly. If you do not have a preprocessor installed, it is recommended to buy one with backwashing performance, double-sided scraping to better clean the filter bottle and filter screen, and discharge the filtered impurities and dirt for transportation.

As for cleaning and draining impurities, the general municipal tap water supply can be pulled after a month of cleaning. If it is a well water or landscape water in a rural area, it is recommended to clean it frequently.

If you don't want to clean so troublesomely, you can consider installing a smart model with automatic cleaning performance, BKA's pre-filter is automatically cleaned, and it will be automatically cleaned when set, and the cost performance is quite high, you can learn about it.

Hello, the pre-filter is very convenient to clean now, as long as the valve is opened, it can be cleaned, basically 1 2 months to clean it.

The pre-filter cleaning method is as follows:

1. First of all, before cleaning the pre-filter, you should check the status of the filter to determine whether it needs to be cleaned. If the filter element has been discolored, or if there is a lot of dirt on the filter, it needs to be cleaned.

2. Secondly, when cleaning the pre-filter, you should first turn off the water source, then disassemble the filter, remove the filter element, clean it with clean water, wipe it dry with a towel, and then install the filter element back, and finally open the water source to check whether there is any water leakage.

3. Finally, after cleaning the pre-filter, the status of the filter should be checked regularly, and the problems should be found and dealt with in time to ensure the normal use of the filter.

Precautions for the purchase of pre-filters

1. Look at the brand.

When buying a pre-filter, you must take a look, its brand is best to choose the filter produced by the big brand, do not choose the small brand or the three no brand, the filter of the big brand is relatively stable, there is no safety hazard.

2. Look at the flushing mode.

There are several flushing modes for the pre-filter, including flushing, backwashing, stacking and siphoning. When choosing a filter, as long as you don't choose to rinse it down, it's fine, because this flushing method can't completely rinse the dirt inside.

3. Look at the material.

It is best to choose a pure copper pre-filter, which can be used for a longer time and has a better effect, or 316 stainless steel can also be used. Do not choose plastic or semi-copper materials, the quality is not good, and bacteria will breed after a period of use.

It also needs to be cleaned after a long time, although the dust of the pre-filter is smaller. But it must also be cleaned after a long time.
