Safety Warnings & Compliance

Pressure Safety: NEVER exceed the maximum operating pressure of 50 PSI. Monitor the gauge closely during initial startup after base replacement.
Zero Pressure: Never attempt to adjust plumbing or unions while the system is under pressure. Bleed air through the relief valve until the gauge reads zero.
Chemical Storage: Do not store chlorine or acid near the tank; corrosive vapors can embrittle the reinforced plastic, leading to structural failure.
💡 Pro-Tips for Successful Installation
  • Alignment Check: Dry-fit your plumbing before gluing. This base is larger than the 50/75 models, and port spacing may differ slightly from your previous setup.
  • Manifold Seating: Ensure the internal manifold snaps perfectly into the center port. A tilted manifold prevents the cartridge from standing straight, making the lid impossible to seal.
  • Level Foundation: Ensure the equipment pad is perfectly level. An unlevel base puts uneven stress on the ports, which can lead to hairline cracks over time.
  • Compatibility Note: Specifically designed for large-format single-cartridge and vertical grid D.E. housings.
Technical Note: Includes the Tank Bottom shell only. Locking rings, internal manifolds, cartridges, and tank O-rings are sold separately.

User Disclaimer: Professional installation is strongly recommended for high-pressure components. Improper assembly can result in equipment damage, leaks, or personal injury.
