Distribute Water Flow Efficiently

A pool manifold helps evenly distribute water through your pool or spa’s plumbing system. It ensures smooth circulation, supporting better filtration and heating performance.

High-Quality Pool Manifold Valves

Our pool manifold valves allow for precise water control, making it easier to manage multiple jets or zones. Built to last, they resist corrosion and wear from pool chemicals.

Spa Manifolds for Relaxing Comfort

A spa manifold ensures balanced jet pressure, giving every seat consistent water flow. It’s a must-have for maintaining a relaxing and efficient spa experience.

Durable Construction for Long Life

Crafted from heavy-duty PVC or ABS materials, our manifolds stand up to tough pool conditions, ensuring long-lasting reliability.

Easy to Install and Maintain

Each pool manifold is designed for straightforward installation and minimal upkeep, saving you time and effort.

Compatible with Various Systems

Whether you’re setting up a residential pool or a commercial spa, our manifolds fit a wide range of plumbing configurations.

Frequently Asked Questions

A pool manifold can crack due to several factors:

  • Freezing temperatures — water trapped inside expands and splits the housing.
  • Excessive system pressure — caused by clogged filters, closed valves, or oversized pumps.
  • Chemical imbalance — high chlorine or low pH weakens PVC or ABS materials over time.
  • Overtightened fittings — placing mechanical stress on manifold joints.
  • UV exposure or age — prolonged sunlight and heat can cause brittleness and microfractures.

To prevent cracking, ensure regular filter cleaning, maintain balanced chemistry, and drain systems before winter.

Replace your swimming pool manifold if you notice:

  • Visible cracks or leaks around fittings.
  • Uneven pressure or poor water distribution across jets or returns.
  • Air bubbles entering the system.
  • Water escaping near the filter or pump connection.

In some cases, yes. Manifold sections and fittings can be replaced individually if the main body is intact. However, if the central manifold or valve body is cracked, a full replacement ensures a secure, long-term solution. Voomi Supply offers both complete manifold assemblies and individual replacement parts to match your needs.

Most pool manifolds are made of PVC or CPVC — materials that provide excellent chemical and temperature resistance. Spa manifolds, designed for air or water distribution, often use ABS or flexible PVC for ease of installation and vibration resistance. CPVC manifolds are best for high-temperature or high-pressure applications.

When selecting a pool or spa manifold, consider:

  • Pipe diameter and connection type (slip, threaded, or barbed).
  • Number of ports or outlets.
  • Application type — water, air, or combination.
  • Material compatibility with your plumbing system.
  • Pool manifolds manage water flow between the filter, pump, and return lines.
  • Spa manifolds distribute air or water evenly to multiple jets for balanced pressure.

Spa manifolds typically have smaller, multiple outlets (¼” to ½”), while pool manifolds handle larger flow volumes (1½” to 2”).

Minor surface cracks can sometimes be temporarily sealed with PVC repair epoxy, but this is not a long-term solution. Since manifolds operate under constant pressure, replacing the cracked part is safer and more reliable. Continuing to use a damaged manifold may lead to leaks, reduced performance, or system failure.
