[0002] Piped drinking water has been widely popularized in the market. In order to ensure the safety of users' water use, the entire clean water tank must be sealed. However, in actual use, it is found that if the electronic level meter fails or the range setting is incorrect, the level measurement will be inaccurate, causing the drinking water in the clean water tank to flood the clean water tank. Sometimes when a large amount of return water comes back, the liquid level in the clean water tank fluctuates greatly, and the clean water tank cannot be filled, causing the drinking water to overflow. This will not only affect the water quality safety, but also affect the system operation, flooding the pump room or electric control cabinet, causing the system to shut down or equipment damage, and even affecting other users, increasing losses. The direct drinking water system that introduces a clean water tank overflow alarm and processing can handle overflow anomalies in a timely manner to ensure the safety of the direct drinking water system.
