Trusted One-Way Flow Protection for Pool & Spa Plumbing Systems

The Jandy Check Valve (Part #7305) is a professional-grade pool plumbing check valve designed to prevent water from flowing backward through pool and spa circulation systems. By allowing water to move in only one direction, this valve helps protect sensitive pool equipment and maintain stable system operation.

Check valves like the Jandy 7305 are a critical component on equipment pads where heaters, salt systems, and elevated plumbing runs are present.

This is a true pool check valve, engineered specifically for swimming pool and spa applications.

Why a Pool Check Valve Is Essential

When a pool pump shuts off or pressure changes occur, water can naturally attempt to flow backward through plumbing lines. Without a check valve, this reverse flow can cause:

• Loss of pump prime

• Heater damage from backflow

• Water draining from raised plumbing lines

• Chemical migration into equipment

The Jandy 7305 check valve automatically closes when flow reverses, helping prevent these common system issues.

Designed Specifically for Pool & Spa Systems

Unlike general plumbing check valves, the Jandy Check Valve 7305 is designed to withstand the demands of pool environments.

Key design advantages include:

• Pool-rated materials compatible with chlorinated water

• Internal sealing designed for continuous circulation

• Smooth flow path to reduce restriction

• Reliable operation under changing pressure conditions

This makes it ideal for installation directly on residential pool equipment pads.

Protects Expensive Pool Equipment

Check valves are commonly installed to protect high-value pool components such as:

• Pool heaters

• Salt chlorine generators

• Chemical feeders

• Elevated water features

By preventing backflow, the Jandy 7305 helps extend the life of connected equipment and reduces the risk of premature failure.

Ideal for New Installations or Plumbing Repairs

The Jandy 7305 check valve is commonly used during:

• New pool construction

• Equipment pad upgrades

• Heater or salt system installations

• Plumbing repairs or replacements

Adding a properly placed check valve is a small upgrade that can prevent costly service calls later.

Engineered for Consistent Flow Performance

Modern pool systems rely on efficient circulation, especially when paired with variable-speed pumps.

The Jandy 7305 is designed to:

• Maintain smooth water flow

• Minimize pressure loss

• Support consistent circulation

• Operate reliably during daily pump cycles

This ensures dependable performance without unnecessary strain on the pump.

Installation Notes

For proper operation, the Jandy Check Valve 7305 must be installed in the correct flow direction.

General installation considerations include:

• Following the flow direction indicator

• Ensuring straight plumbing alignment

• Allowing access for future service

• Using pool-approved installation practices

Professional installation is recommended for optimal performance and long-term reliability.
