Key Features
Spherical Tank Design
The ProSeries Plus spherical tank evenly distributes pressure and stress across the entire tank surface — greater strength and longer life than standard cylindrical designs, particularly for demanding high-flow applications.
36" / 6.7 Sq Ft — Demanding Applications
Sized for large residential and semi-commercial pools, in-floor cleaning systems, solar heating systems, and water features.
Tank Only — Valve Sold Separately
Ideal for replacements where the existing valve is being reused, or for new installations where the valve is specified separately.
All ProSeries Advanced Features
Built on the proven ProSeries platform — umbrella-fold laterals, corrosion-proof materials, and the performance features that define the ProSeries line.
Who It's For
- Large residential and semi-commercial pool installations requiring the ProSeries Plus spherical tank strength
- In-floor cleaning system and solar heating system installations where the standard ProSeries is undersized
- Replacements for existing S360SX tanks where the valve is being reused

Frequently Asked Questions
What is the advantage of the ProSeries Plus spherical tank over a standard cylindrical tank?
A spherical tank distributes internal pressure evenly across its entire surface — there are no stress concentration points at corners or edges. Standard cylindrical tanks concentrate stress at the end caps and seams under high pressure. For demanding applications like in-floor cleaning systems, solar heating, and large pools with higher flow rates, the spherical design provides greater long-term structural integrity and resistance to pressure fatigue.
What valve is compatible with the S360SX?
The S360SX is compatible with Hayward side-mount VariFlo valves. Consult your pool professional or Hayward's compatibility guide to confirm the appropriate valve for your installation's flow rate and plumbing configuration.
