If you encounter resistance when lowering Simple Pump drop pipes during installation, several factors could be causing the obstruction.
Common Causes of Blockage
1. Submersible Pump and Piping
Most common cause - Your existing submersible pump occupies space in the well.
Signs:
- Obstruction at consistent depth
- Can sometimes work around it
- More common in smaller casings
Solutions:
- Carefully work drop pipe around submersible
- Consider larger casing if upgrading well
- Professional installation may help
2. Well Casing Obstructions
Offset casing joints - Where casing sections join, slight misalignment can catch drop pipes.
Signs:
- Obstruction at specific depth
- May be able to twist past it
- Repeated obstruction at same point
Solutions:
- Rotate drop pipe while lowering
- Apply gentle downward pressure
- If severe, consult well professional
Collapsed or damaged casing - Older wells may have structural issues.
Signs:
- Major blockage
- Can't pass at all
- May indicate serious well problem
Solutions:
- Well inspection by professional
- May require well rehabilitation
- Consider new well if severe
3. Mineral Deposits and Scale
Builite/scale buildup - Mineral deposits accumulate inside casing over time.
Signs:
- Rough spots during insertion
- May be multiple locations
- More common in hard water areas
Solutions:
- Well cleaning/rehabilitation
- Acid treatment by professional
- Regular maintenance schedule
4. Debris in Well
Sand, gravel, or objects - Material that has fallen or accumulated in well.
Signs:
- Soft obstruction
- May shift when contacted
- Bottom of well affected
Solutions:
- Well bailing to remove debris
- Professional cleaning
- Avoid dropping anything during installation
Troubleshooting Steps
Step 1: Identify the Depth
- Note exactly where obstruction occurs
- Compare to well records
- Determine if consistent or intermittent
Step 2: Try Gentle Rotation
- Slowly rotate drop pipe assembly
- Apply light downward pressure
- See if pipe will pass obstruction
Step 3: Inspect from Above
- Use flashlight to look down well
- Check for obvious obstructions
- Note casing condition
Step 4: Consider Professional Help
If you cannot identify or pass the obstruction:
- Contact well service company
- May need downhole camera inspection
- Professional can assess well condition
