Is it normal for the Mijia Smart Water Purifier N800G to have a delay of a few seconds when opening the water tap?

Question

Accepted Answer

Yes, a brief delay of 1–2 seconds when opening the purified water tap of the Mijia Smart Water Purifier N800G is normal. The purifier employs an automatic water pressure control system to maintain consistent water flow and protect the internal RO membrane.
When the tap is opened, air and residual water in the purified water hose are first expelled. During this short period, the water flow appears slower or intermittent. Once the air is cleared and the system stabilizes, normal water flow resumes, providing the expected purification efficiency and flow rate.
This design ensures safe and efficient operation while preventing sudden pressure surges that could affect internal components. This short delay is part of the normal startup behavior of the Mijia Smart Water Purifier N800G.
