Radiant pools are known for their insulated walls, energy efficiency, and hybrid design options. Whether installed above ground, semi-inground, or fully inground, these pools are a favorite for their strength and versatility. But like any pool system, Radiant pools are not immune to problems.
This guide explores the most common Radiant pool problems—what causes them, how to fix them, and how to avoid costly mistakes during installation or ownership.
1. Pool Wall Bowing or Buckling
Quick Answer: Wall bowing or warping in Radiant pools often results from incorrect backfilling, soil pressure, or water imbalance during or after installation.
Common Causes:
- Uneven backfill: Applying soil pressure without enough internal water weight.
- Excessive groundwater: Hydrostatic pressure can force the wall to bow inward.
- Incorrect installation depth: Semi-inground or inground setups must follow manufacturer depth guidelines.
Fix: Carefully remove soil and re-level the backfill evenly. Ensure water is present in the pool during backfilling to stabilize the structure. In severe cases, consult your installer or builder.
2. Leaks in Liner or Wall Seals
Quick Answer: Leaks in Radiant pools typically occur around liner seams, skimmers, returns, or the base of wall panels due to poor sealing or liner shifts.
How to Identify and Repair:
- Use dye test kits: To pinpoint small leaks in the liner or near fittings.
- Check gasket seals: Especially around skimmer and return fittings.
- Inspect liner seams: Especially if the pool has been drained recently or gone through temperature extremes.
Recommended Product: Use Anderson Leak Detection Dye Kit for locating small leaks, and patch with Boxer Underwater Vinyl Patch Kit.
3. Settling or Uneven Pool Base
Quick Answer: An uneven pool floor or shifting base is typically caused by improper ground preparation or soil settling over time.
Prevention and Repair:
- Ensure a compacted base: Before installation, compact the ground properly and add a layer of sand or foam.
- Monitor for erosion: Heavy rain can cause soil to wash out from under the base, especially on sloped properties.
- Re-level and patch: In minor cases, drain the pool partially and re-level using a hand tamper and new base material.
Pro Tip: Use a foam cove kit along the base perimeter to prevent liner stress and support corners.
4. Rust or Corrosion (Metal Components)
Quick Answer: Although Radiant pool walls are made of corrosion-resistant aluminum, rust can occur on screws, plates, or other metal components if improperly maintained.
What to Look For:
- Rust stains on coping or near metal hardware
- Discoloration near wall seams or panels
- Corroded pool ladders or rails
Fix: Clean rust using a non-abrasive rust remover. Replace severely corroded parts with stainless steel or coated alternatives. Always rinse and dry metal areas after saltwater exposure.
Recommended Product: Use Star Brite Rust Stain Remover and follow up with Corrosion Block Spray for protection.
5. Liner Wrinkles or Slips
Quick Answer: Liner wrinkles are caused by improper installation, draining and refilling, or ground movement. A slipping liner may indicate the liner bead has come loose from the track.
How to Fix:
- Wrinkles: Gently heat the area with warm water or sun exposure, then use a pool brush or plunger to smooth out the liner.
- Bead slip: Re-seat the liner bead into the coping track. Use a bead wedge or liner lock strip if needed.
Helpful Tool: A Liner Lock Bead Wedge Kit secures the liner in place and prevents future slipping in semi-inground installations.
6. Insulation Panel Damage
Quick Answer: The patented radiant insulated wall panels can be damaged during transport, installation, or due to heavy impact. This reduces energy efficiency and can weaken structural integrity.
Prevention & Repair:
- Handle all panels carefully during install—don’t drag across surfaces.
- Avoid over-tightening bolts or screws into wall panels.
- For minor dents, the insulation still functions. For cracks or punctures, consult the manufacturer for replacement options.
Warranty Tip: Radiant Pools often include a limited lifetime warranty—document any visible damage early for potential coverage.
7. Difficult Winterization and Freezing Issues
Quick Answer: Radiant pools in colder climates may suffer from freeze damage if not properly winterized, especially at plumbing connections and skimmer lines.
Winterization Checklist:
- Lower water level below skimmer
- Blow out all lines and plug returns
- Use a winter cover and air pillow to reduce ice pressure
- Add antifreeze to return lines if needed
Suggested Product: Use Pool Antifreeze and Winter Plug Kit to protect pipes and fittings in freeze-prone zones.
Radiant Pool Troubleshooting Table
| Problem | Cause | Solution |
|---|---|---|
| Wall bowing | Improper backfill or hydrostatic pressure | Relevel soil and follow fill instructions carefully |
| Liner wrinkles | Drain/refill cycles, loose bead | Heat and smooth, re-seat liner in track |
| Leaks | Fitting seal failure or liner puncture | Patch liner, tighten or reseal fittings |
| Base settling | Poor ground compaction | Relevel with sand or foam base |
| Rust | Metal hardware exposed to elements | Clean, replace, and protect with spray coating |
Radiant Pool Maintenance Tips
Monthly:
- Inspect liner and wall connections
- Check for ground movement or erosion
- Clean debris from coping and trim areas
Seasonally:
- Test water balance—especially calcium hardness
- Check fittings, return jets, and skimmer gaskets
- Rinse and dry any exposed metal parts
Maintenance Kit: Try the Radiant Pool Maintenance Bundle with liner patch kit, coping clips, pH test strips, and rust cleaner.
When to Call a Pro
While most issues can be handled by an experienced DIY pool owner, certain signs should prompt a call to your installer or pool technician:
- Cracked wall panels or major structural shifts
- Persistent liner leaks or bead detachment
- Sinking or severely sloped pool base
Conclusion: Keep Your Radiant Pool Problem-Free
Radiant pools offer long-lasting performance and great insulation, but only if properly installed and maintained. Most issues—from wall bowing to liner slips—can be avoided with smart preparation and routine checks.
