Online timer for 82 seconds
Start the 82 seconds after you remove the rainwater tank filter, then leave the countdown running while you fetch a brush, rinse the housing or put nearby tools away. The short window keeps that other job contained, so you return before loosened leaves and grit dry onto the mesh.
Cleaning around a rainwater tank can leave your hands wet or muddy, so you may not want to carry the device with you. If it is in silent mode, keep it somewhere you can see the screen flash or feel its vibration when you come back. This avoids an audible alert disturbing anyone nearby while still giving you a clear finishing cue.
Match the interval to the filter rather than stretching the cleaning to fill the countdown. A lightly coated inlet screen may only need a quick rinse, while fine dust, eucalyptus debris or residue after a dry Australian spell can take longer to release. If the mesh is clear early, stop; if dirt remains, restart only after checking whether soaking or gentler brushing suits the material.
Common questions
What could make this countdown too short for cleaning a rainwater tank filter?
Compacted leaf fragments, fine dust and dried residue can require more soaking or brushing than the interval allows. Pause to inspect the mesh, then run another short countdown if material is still caught.
What if the filter is clean before this countdown finishes?
Stop the timer and refit the filter once the mesh and housing are clear. There is no benefit in continuing to scrub merely to use the remaining time.
