This pertains to those who are using WELLS for the water supply. Wells that use ELECTRICITY to draw the water up and into the house. Therefore, ON SHABBAT: when using the 'faucet' or when flushing the 'toilet,' electricity is being used in the same way as when 'switching' on the light switch, for which on Shabbat there is a special cover to prevent turning on or off, or is on a timer to stay on until whenever. So, why is this 'allowable'? 2. This pertains to opening and closing the refrigerator and/ freezer door ON SHABBAT: Although the inside light is unscrewed so as not to 'come on' when the door is opened, the compressor (or whatever it is called), which uses electricity, 'comes' on (via electricity) when the door is opened. Why is this allowable?
