Installation Instructions for Drive Well Points
NOTE: Determine the depth of the water table before beginning. Do not try to drive a well point to depths greater than 50 feet. Most pumps are only capable of lifting water 20-25 feet. Keep all pipe joints tight to eliminate air leaks when pump is installed.
- Bore a starter hole 3" to 6" in diameter and 2' to 3' deep. Bore this hole with a post hole digger or hand auger.
- Attach a length of pipe to the point using a coupling. Place the drive cap over the open end of the pipe. Always use two wrenches turning in opposite directions. IMPORTANT: Before use, remove plastic protective jacket around screen.
- IMPORTANT: Place point and pipe into the hole making sure it is perfectly square.
- To drive point use either a sledge hammer or a 2" or 3" pipe with a weighted end, also called a steel post driver. A pipe driver can be made by filling a 4' or 5' long pipe 1/3 to 1/2 full with lead.
- Drive the well point and pipe into the earth. Remove the drive cap and add pipe as desired. Rotate clockwise from time to time using a pipe wrench to ensure tight couplings. Drive until water table has been penetrated five to ten feet. CAUTION: Drive only with Drive Cap on!
- Clean the well by using either a surging technique or washing with a garden hose. To surger, place a long pole below the water level and push up and down to surge the water through the perforated point.
- Install pump on pipe at the surface. Operate pump to clean and remove foreign material.
