How do I ground and backfill my Plungie pool?
This article covers the essential work after your Plungie pool has been placed: completing the electrical grounding and properly backfilling the shell. This stage is critical for safety, long-term stability, and keeping your project compliant with local codes and Plungie’s warranty requirements.
1. Electrical Requirements
All electrical work must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and any additional local jurisdiction requirements.
Standard Electrical Provisions:
Plungie pools come pre-installed with:
-
1 x 12V LED pool light
-
Bonding points
-
Provision for an equipment bonding loop
The electrician must:
-
Connect the light via an appropriate transformer
-
Bond all metallic components (as required by NEC)
-
Ground the pool structure using the pre-installed bonding points
-
Ensure GFCI protection is installed per code
Tip: The LED light transformer should be placed near the equipment pad for easy access and maintenance.
2. Backfill Requirements
Backfilling refers to filling in the space between the pool shell and the surrounding excavation. Done correctly, this process keeps the pool stable and prevents movement.
Approved Backfill Material:
-
Use clean, non-expansive, granular fill such as AASHTO #57 stone
-
DO NOT use clay, organic material, or expansive soils
Placement Guidelines:
-
Place material in 12-inch lifts, working evenly around the pool
-
Lightly compact each lift—avoid heavy mechanical compaction that could stress the shell
-
Fill the pool with water as you backfill to equalize pressure on both sides of the shell
Reminder: Never allow water to accumulate outside the shell without matching the internal water level.
3. Drainage Strategy
Backfill must allow water to flow away from the pool:
-
Slope hardscape and landscape grading away from the shell (minimum 1:50)
-
Consider perimeter trench drains or subsurface drains in high water table areas
-
Ensure finished surfaces minimize standing water near the pool
4. Call for Inspection (If Required)
Before completing the backfill, check with your local authority to determine:
-
If a bonding inspection is required before covering any connections
Leave all connections visible and accessible until the inspector signs off.
FAQs
Q: Can I do the electrical work myself?
A: No. A licensed electrician must handle all wiring, bonding, and grounding per NEC.
Q: Is sand okay for backfill?
A: No. Only use approved granular materials like crushed stone or gravel.
Q: Why do I need to fill the pool with water during backfill?
A: This prevents uneven pressure that could cause the shell to shift or crack.
Q: How do I bond the pool?
A: Use the grounding lugs provided on the pool and connect them to an equipotential bonding loop.
Summary: Electrical and backfill are high-stakes phases of your Plungie installation. Hiring licensed professionals and using the right materials will protect your investment, meet safety standards, and ensure long-term pool performance. Always coordinate inspections and follow Plungie’s engineering recommendations for a smooth finish.
