| Problem | Cause | Remedy |
|---|---|---|
| D.E. is leaking back to pool | After back washing and re-coating the filter with D.E., some amount of "puff-back" is normal. | The D.E. will eventually be filtered out of the pool. No action is necessary. |
| Damaged grid or O-Ring in filter assembly. | Replace damaged grids or O-Ring. | |
| Improper assembly of internal parts. | Correct assembly of parts. | |
| Missing or defective check valve. | Install or repair check valve. | |
| Dirt or D.E. buildup on poppet seal O-Ring | Clean O-Ring. | |
| Dirt or D.E. build-up on O-Ring that seals vortex chamber to air relief body. | Clean O-Ring. | |
| O-Ring damaged. (Either of the above.) | Replace O-Ring. | |
| Pool water not sufficiently clean | Improper precoat of D.E. on grids. | Use recommended amount of D.E. |
| Inadequate turnover rate. | Consult dealer or pool service technician. | |
| Pool chemistry not adequate to inhibit algae growth. | Maintain pool chemistry or consult pool service technician. | |
| High filter pressure after back washing | Insufficient back washing. | Back wash until effluent runs clear. |
| Filter cloth plugged with D.E. and contaminants. | Manually clean filter grids. | |
| Filter cloth plugged with mineral deposits. | Chemically clean filter grids. | |
| Partially closed valve or restriction in return line. | Open valve or remove obstruction in lines. | |
| Return flow to pool diminished. Low filter pressure. | Obstruction in pump hair and lint strainer. | Clean basket in strainer. |
| Obstruction in pump. | Disassemble and clean pump. | |
| Obstruction in suction line to pump. | Clean skimmer basket. Remove obstruction in lines. Open valves in suction line. | |
| Short cycles | Improper back wash. | Back wash until effluent runs clear. |
| Pool chemistry not adequate to inhibit algae growth. | Maintain pool chemistry or consult pool service technician. | |
| Improper precoat of D.E. on grids. | Use recommended amount of D.E. | |
| Plugged grids. | Manually clean or chemically clean as required. | |
| Leakage at clamp | Improper torque on closure band hardware. | Reassemble clamp following procedure under "Assembly". |
| Debris contamination on O-Ring and flanges. | Clean O-Ring and flanges. Lubricate O-Ring. | |
| Cut or damaged O-Ring. | Replace O-Ring. | |
| Corrosion pits on flanges. | Replace tank and consult pool service technician for source of corrosion. |
