Yes, in most cases Simple Pump can be installed in a 4-inch well alongside an existing submersible pump with pitless adapter. However, clearance can be tight, so careful planning is important.
4-Inch Well Clearance Overview
What Fits Inside 4" Casing
- Simple Pump components: ~1.5" diameter
- Typical 4" submersible: 3.5-3.75" diameter
- Submersible pipe: ~1-1.25" diameter
- Electrical cable: ~0.5" diameter
The Challenge
4-inch casing has limited space with a submersible installed. Success depends on your specific submersible size and how components are positioned.
Factors Affecting Fit
Submersible Pump Size
- Smaller submersibles (1/2 HP) = more room
- Larger submersibles (3/4+ HP) = tighter fit
- Check your submersible specifications
Pitless Adapter Configuration
- Pitless adds complexity at that depth
- Both systems can share pitless
- Or Simple Pump can pump through cap
Drop Pipe Path
- Simple Pump drops straight down
- Must clear submersible and piping
- May need to work around obstacles
Installation Approaches
Option 1: Work Around Submersible
- Carefully lower Simple Pump beside submersible
- Takes patience and care
- Most common approach
Option 2: Tie Into Pitless
- Simple Pump connects to existing pitless
- Shares underground piping
- Professional installation recommended
Option 3: Pump Through Well Cap
- Simple Pump delivers through cap
- Separate from submersible piping
- Simpler installation
Professional Installation Recommended
For 4-inch wells with submersibles, consider professional installation:
- Experience with tight clearances
- Proper handling techniques
- Avoid damaging submersible
- Ensure proper alignment
Clearance Tips
During Installation
- Lower slowly and carefully
- Rotate to find clear path
- Don't force past obstructions
- Use helper for guidance
Signs of Clearance Issues
- Consistent contact at one depth
- Cannot lower further
- Scraping or binding
If You Encounter Problems
- Don't force components
- Pull up and try different angle
- Consider professional assistance
Alternatives if Clearance is Insufficient
Larger Casing
If upgrading well is planned:
- 5" or 6" casing provides comfortable clearance
- Discuss with well professional
- May be worthwhile investment
Simple Pump Only
If submersible is being removed:
- Full clearance for Simple Pump
- Dedicated backup system
- No interference concerns
