A relatively conservative estimate for installing a Â¾ or full bathroom in a basement is $8,000 to $12,000. Installing a Â½ bath in the basement might cost as little as $5,000.
The refrigerator water supply line connects to a water inlet valve installed inside the bottom of the refrigerator. The line supplying water to your ice maker attaches to the valve. When the ice maker requires water, it sends an electric signal to the inlet valve to open and allow the water to fill the mold in the ice maker.
If the water is coming from the back of the refrigerator its most likely from the icemaker water valve. To check this you have to remove the back cover and inspect the valve. If itâs leaking replace it. But it might not leak unless its running water.
