1. First of all, close the main tap water valve in time to prevent water from continuing to flow out, causing greater losses.

2. Secondly, it is necessary to check whether the water pipe leaks or is broken, and you can find the specific location for maintenance.

3. Then, if there is no water leak or rupture in the water pipe, it is that the faucet is not closed properly or the valve is not closed properly when the pool drains. It is necessary to check whether the faucet and pool valve are closed.

Finally, all the above measures are invalid. You can contact the local water supply company, ask for help to check whether there are other problems in the water supply pipeline, and assist in handling them.
