Common Issues & Troubleshooting
Solutions to the most common IBC tank problems.
Valve Won't Close Completely
Symptoms: Slow drip or seepage when valve is closed
Causes: Worn ball/seat, debris in valve, damaged O-rings
Solutions:
- Flush valve with water to remove debris
- Replace O-rings if visible damage
- Replace entire valve if worn ($35-85)
Slow Flow Rate
Symptoms: Product dispenses slower than expected
Causes: Partial blockage, vent issue, product viscosity
Solutions:
- Check and clean valve and outlet
- Ensure top vent is open during dispensing
- For viscous products, use larger valve or pump
Lid Seal Leaking
Symptoms: Moisture or odor escaping from top
Causes: Worn gasket, improper seating, damaged lid
Solutions:
- Check gasket for cracks or compression set
- Clean sealing surfaces of debris
- Replace gasket ($5-15) or lid if damaged
Bottle Swelling or Bulging
Symptoms: Tank appears expanded, doesn't sit flat
Causes: Chemical attack, overfilling, pressure buildup
Solutions:
- Verify chemical compatibility immediately
- Never fill past 90% capacity
- Ensure proper venting
- Replace tank if structurally compromised
Odor Retention
Symptoms: Previous contents can still be smelled
Causes: Absorption into HDPE, inadequate cleaning
Solutions:
- Triple-rinse with hot water
- Use appropriate cleaning agents
- Sunlight exposure can help (limited time)
- Some odors cannot be fully removed
Cage Rust
Symptoms: Orange discoloration, flaking on steel cage
Causes: Outdoor exposure, moisture, damaged coating
Solutions:
- Wire brush loose rust
- Apply rust converter
- Prime and paint with rust-inhibiting paint
- Store indoors or use covers

How to Properly Clean an IBC Tank
Step-by-step cleaning process for different applications:
- Completely drain the tank through the valve
- Remove top lid and inspect interior
- Rinse with hot water (140-180°F) using a spray wand
- Apply appropriate cleaning solution (food-safe or industrial)
- Agitate or pressure wash all interior surfaces
- Rinse thoroughly until no residue remains
- Inspect for cleanliness and dry completely
- Reinstall lid and valve caps for storage
How to Replace an IBC Valve
Valve replacement procedure:
- Ensure tank is completely empty and drained
- Place bucket under valve to catch residue
- Unscrew old valve counterclockwise (may need wrench)
- Inspect gasket seat for damage
- Apply thread tape to new valve threads (3-4 wraps)
- Hand-tighten new valve, then snug with wrench
- Test for leaks with water before use
- Do not overtighten - may crack fitting
Proper IBC Tank Stacking
Safe stacking guidelines:
- Empty tanks: Maximum 4-high with same size/style
- Full tanks: Maximum 2-high (only certain tanks rated)
- Surface: Level, stable concrete or compacted ground
- Alignment: Stack directly centered, corners aligned
- Inspection: Check cage integrity before stacking
- Never stack: Damaged tanks, mixed sizes, or on soft ground
Winter Storage Preparation
Protect tanks from freeze damage:
- Drain all liquid from tank and valve
- Open valve to allow any trapped water to drain
- Leave lid slightly open for ventilation
- Store indoors if possible
- If outdoors, cover to prevent snow/ice accumulation
- Never leave filled tanks to freeze - will crack
- Insulate heated blankets for tanks that must stay full
