Now, this is actually less than the original quote, but still an exorbitant amount for a tablet that cost me $229. However, Iâd like to draw your attention to the above image, sent to me of my tablet by the ASUS repair center.
1 You'll feel a slack in the line. 2  At the point where you feel the slack, mark the line at the top edge of the casing (you can tie a small knot in the line, use tape or a marker). 3  Pull the line back up from the casing. 4  Measure the length of the line from the bobber to the marked line. 5  This is your static water level.
Answer: There is no reason to put the hand pump close to the bottom unless it is a shallow well to begin with where you have limited space. If you can, maintain the 20' below static water level. If you are unable to do that then try to get as much cover as you can get over the pump. The pump will operate in as little water as 2'. The reason for the 20' below the water recommendation is to give a reasonable area for water recovery as you pump.
