User Tips

- Battery Life: While the timer has a long standby time, consider using high-quality alkaline batteries for consistent performance, particularly in colder weather.
- Leak Prevention: Always double-check all connections to the faucet and hoses. A small amount of thread seal tape can be very effective in preventing minor drips.
