Proper handling of Simple Pump PVC drop pipes ensures successful installation and long-term reliability. This guide covers best practices for handling Schedule 80 PVC components.
Drop Pipe Specifications
Material
- Type: Schedule 80 PVC
- Size: 1" nominal diameter
- Threads: Male NPT
- Strength: Highest rated PVC schedule
Why Schedule 80?
- Thicker walls than Schedule 40
- Higher pressure rating
- Better thread strength
- Long-term durability
Handling Guidelines
Storage
Before Installation:
- Store in dry location
- Protect from direct sunlight (UV)
- Keep away from heat sources
- Store horizontally on flat surface
- Avoid bending or deflection
Temperature Considerations:
- PVC becomes more brittle when cold
- More flexible when warm
- Ideal handling: 60-80°F
- Allow to acclimate if stored in cold
Transportation
Moving Pipes:
- Support along length
- Don't carry by one end
- Avoid impacts and drops
- Protect threaded ends
- Bundle securely if multiple
Thread Protection
Critical Areas
The male NPT threads are precision machined:
- Protect from impacts
- Keep clean and dry
- Don't cross-thread
- Inspect before installation
Protective Caps
If provided:
- Leave on until installation
- Replace if removed for inspection
- Don't force onto threads
Installation Best Practices
Thread Preparation
Teflon Tape Application:
- Maximum 3 layers (maintenance)
- Maximum 5 layers (new installation)
- Wrap in direction of threads
- Cover threads completely
- Never use liquid sealant or pipe dope
Thread Engagement
Thread engagement must not exceed 5/8 inch. Over-tightening can damage threads or crack pipe.
Proper Technique:
- Apply Teflon tape
- Hand-tighten first
- Continue to snug (firm hand pressure)
- Do not use excessive force
- Verify 5/8" maximum engagement
Coupler Connection
When connecting to stainless steel coupler:
- Clean threads
- Apply Teflon tape to male threads
- Thread by hand first
- Tighten firmly but not excessively
Avoiding Common Problems
Cross-Threading
Prevention:
- Start threads by hand
- Align carefully before turning
- If resistance felt, back off and restart
- Never force connection
Signs of Cross-Threading:
- Difficulty threading
- Uneven engagement
- Visible thread damage
- Leaks after installation
Over-Tightening
Problems Caused:
- Cracked pipe
- Damaged threads
- Difficult disassembly later
- Potential leaks
Proper Tightness:
- Firm hand-tight
- Perhaps 1/4 turn past hand-tight
- Should not require tools for initial tightening
- Wrenches for final snugging only
Impact Damage
Avoid:
- Dropping pipes
- Striking against hard surfaces
- Standing pipes on end (stress concentration)
- Letting pipes swing and hit objects
Cold Weather Handling
Extra Caution When Cold
PVC is more brittle in cold temperatures:
- Handle more carefully
- Avoid impacts completely
- Warm gradually before installation if very cold
- Don't force connections
Acclimation
If pipes are cold:
- Bring to room temperature
- Allow several hours
- Handle gently until warmed
Inspection
Before Installation
Check each pipe for:
- Crack or damage
- Thread condition
- Straightness
- Cleanliness
Reject If:
- Visible cracks
- Damaged threads
- Significant scratches
- Deformation
After Installation
Protecting Installed System
Once in well:
- Cap well properly
- Protect from debris
- Verify connections before lowering further
- Inspect periodically
