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.
Mine was only 145 feet deep, being in SW Florida, the water table is very high. The cost for the pump and piping was 950 dollars. Good luck on having a pump replaced. Our well is 465 feet and the wiring was found to have broke and frayed at about 200 feet. The original pump was found to be in working order, but since it was 16+ years old, we opted to replace it and upgrade to 5HP. The wiring and pipe was also replaced. Total cost: $3659.
