After a period of time, it is necessary to manually open the sewage pipe to flush and discharge the filter, but at present, the flushing and discharge of the filter is manual operation, which cannot guarantee timely sewage treatment.

2. Water pressure requirements for indoor water equipment, such as water heaters cannot be started when the water pressure is too low, and water pipes or faucets and other equipment will be damaged if the water pressure is too high. This equipment can monitor the water pressure in real time to protect downstream waterway equipment stability.

3. It is often the case that the faucet is turned on and forgotten to be turned off when the water is cut off, and then the water comes in while going out, or directly forgets to turn off the water hole head to go out, which not only causes waste of water resources, but also causes great economic pressure on the user. In real life, there are often unprovoked losses caused by pipe breaks and leaks, such as water soaking in the floor, and water leakage causing damage to other lower floors. Cause very big economic loss, and waste time and energy.
