How do you measure well depth?
– Lower until you feel slack. Note, you may feel some bouncing as you pass the pump depending on the space from the casing to the weight on the measuring line. – Mark the line at the top edge of the casing. – Pull out and measure. This is your well depth – the distance to the bottom of the well shaft.
How do you measure the depth of a well?
accurate, and low cost method to measure depth to water in a well, is by using an ordinary tape measure. One marked with feet, tenths, and hundredths of feet is ideal. The depth is limited to slightly less than 100 feet unless you have a very long tape. It is very helpful to know the approximate depth to water. This method is
