How to use the online timer
Leave the watering can beneath the water-butt tap, start the forty-eight-second countdown, and use the brief gap to fetch gloves or put away a trowel. The interval suits a quick fill when the butt is reasonably full and the tap runs freely, without keeping you beside it watching the water rise. When the alert sounds, return before the can becomes awkward to carry or starts spilling onto the path.
While you are away from the can, your phone may dim or lock before the alert is due. That does not necessarily stop the countdown, so there is no need to keep waking the display with damp or muddy fingers. Keep the sound audible from the shed or flower bed, and avoid leaving the handset where a British shower could reach it while you finish the other small job.
Returning to the water butt after the alert gives you a useful point for judging the flow. If the can is short of the level you need, note whether the butt is running low, as reduced pressure can make the same interval less effective. If it is already full, close the tap first, then move the can steadily; the interruption is easier to recover from when the path back has been left clear.
Common questions
Why might the watering can fill sooner than the set interval?
A full water butt creates stronger flow, while a wide, unobstructed tap can fill a smaller can sooner. Close the tap when you return rather than letting the remaining seconds cause an overflow.
What if the watering can is still low when the alert sounds?
Recent dry weather may have left the water butt low, reducing the pressure at its tap. Let the can continue filling while you stay nearby, then use that result to judge a slightly longer interval next time.
