Safety Warnings & Critical Installation

Maximum Pressure: Never exceed a working pressure of 50 PSI. Excessive pressure during testing or operation can lead to catastrophic tank failure.

Air Entrapment: You must open the manual air relief valve on the lid to purge all trapped air before startup. Compressed air can cause the tank lid to separate violently.

Plumbing Seal: Do not use pipe joint compound or solvent glue on bulkhead threads; rely solely on the O-ring seals for a watertight fit.

💡 Pro-Tips for System Stability

O-Ring Maintenance: Always install a new, lubricated O-ring (standard #O-343) when replacing the bottom to ensure a vacuum-tight seal with the upper lid.
Anchoring bosses: Utilize the built-in mounting bosses to anchor the filter to a concrete pad. This prevents pipe stress from pump vibration or surges.
Lubrication Rule: Use only silicone-based lubricants on bulkhead O-rings. Petroleum-based products can degrade the thermoplastic material over time.
Model Support: Compatible with Clean & Clear, Predator, EasyClean, and Warrior (44 GPM) series filtration units.
