What if you simply reduced the flow (usually there’s an external valve) as much as possible without disturbing your son’s enjoyment, and then measured the hourly volume used, and then ran the numbers on the cost per hour? We have a temporary pool we put up each year and it holds 16,000 litres, due to that I worked out water costs and for the first allotment per month (it is tiered here), water is very cheap. You may find the hourly cost to be well worth your son’s happiness and ensuing familial peace.
