Log truncation deletes inactive virtual log files from the logical transaction log of a SQL Server database, freeing space in the logical log for reuse by the Physical transaction log. If a transaction log is never truncated, it will eventually fill all the disk space allocated to physical log files.
Clogs in your well pump can be fixed for $100 to $300, depending on where the clog is. Repairing broken inlet or outlet hoses are more expensive. Often times, repair cannot be possible if the damage is to the unit itself. If the unit is repairable, expect a cost of $200 to $500 to repair the pump to working form. Pipe breaks underground are another matter. If you are experiencing a loss of water pressure in the system, chances are there is a leak somewhere in the line.
Medium depth Well: for wells up to 200 ft deep, many pump choices are available. With modern casings and well caps, contamination is rarely a problem. Deep Well: for wells 200 ft to 450 ft, the pump choices go down, while the cost of the well and the pump system can exceed $10,000. Contamination is rarely a problem with the well itself. Very Deep Well: for wells over 450 ft, you have fewer choices still. Well drilling & pump costs combined can exceed $20,000.
