estimated
2. Steel piping (if used) is corroded or
limed, causing excess friction
3. Piping is too small in size
4. Pump not being supplied with
enough water
1. A deep well jet will be needed if
the water being pumped is more
than 25 ft. (7.6 m) depth to water
2. Replace with plastic pipe where
possible, otherwise with new steel
pipe
