Solar-powered automatic water filling systems are prone to leaks; adding a solenoid valve along with a timer switch solves this problem
Thread Content
Automatic water supply using solar energy tends to cause leaks; what should be done? Remove a solenoid valve from a faulty fully automatic washing machine, and attach a timer switch that triggers water supply once between 11 p.m. and 12 a.m., and once again between 8 a.m. and 8:30 a.m.; this will solve the problem, and in that case the leakage will last at most 1 hour.
Waste utilization – how to deal with timers?
You can buy one on Taobao for over ten yuan.
The image sent cannot be displayed. It’s a timed switch that receives 220V electricity; the output is connected to the two wires of the solenoid valve. When electricity is supplied, the valve opens, and when there is no electricity, the valve closes. By setting the timing for electricity supply, one can determine the time at which water is supplied.
Timer switches have inputs and outputs: the input is connected to the power supply, while the output is connected to the timing valve. Timer switches are available for purchase online; solenoid valves can be obtained from those who collect used household appliances – you can offer them a cigarette or 2–3 yuan in exchange for it. By adding an external thread and a elbow, the disconnected water supply line can be reconnected.
