How to install the pre-filter
The pre-filter is an important part of the household water purification system. It can effectively filter large particle impurities such as sediment and rust in tap water and protect subsequent water purification equipment. This article will introduce in detail the installation steps and precautions of the pre-filter, as well as the hot topics related to water purification in recent hot topics on the Internet.
1. Pre-filter installation steps
| steps | Operating Instructions |
|---|---|
| 1. Select installation location | It is usually installed behind the household water meter or at the kitchen water inlet to ensure sufficient space and easy maintenance. |
| 2. Close the main water valve | Before installation, the household main water valve needs to be closed to avoid water splashing. |
| 3. Cut the pipe | Use professional pipe cutting tools to cut the pipe at the selected location. |
| 4. Install the filter | Connect the filter inlet and outlet to the pipe, paying attention to the direction (the arrow points to the direction of water flow). |
| 5. Connection sealing | Use raw tape or sealant to ensure the joints are leak-free. |
| 6. Test for leaks | Open the water valve and check whether there is water leakage in each interface. If there is water leakage, it needs to be resealed. |
2. Installation precautions
1.Installation direction: The pre-filter has clear water inlet and outlet markings, and must be connected strictly in the direction of the arrow during installation.
2.Flush regularly: Most pre-filters have a flushing function, and it is recommended to flush them manually once a month to extend their service life.
3.Antifreeze in winter: If installed outdoors or in a low-temperature environment, insulation measures must be taken to prevent frost cracking.
4.Hydrostatic test: After the installation is completed, the household water pressure needs to be tested to ensure that it is within the allowable range of the filter (usually 0.1-0.5MPa).
