Prevents costly backflow damage in your pool's chemical delivery system. This precision-engineered check valve ensures one-way flow through 1/4" tubing, protecting your sanitizer equipment from reverse pressure that can cause pump damage, chemical contamination, and system failures.

Technical Specifications:

  • Connection Size: 1/4" tube inlet × 1/4" tube outlet
  • Function: One-way flow control and backflow prevention
  • Material: Chemical-resistant polymer construction
  • Pressure Rating: Suitable for standard pool system pressures

Compatible Systems:

  • Salt chlorine generator chemical feed lines
  • Ozone system tubing networks
  • Chemical feeder discharge lines
  • Any 1/4" tube system requiring backflow protection

Pro Tip: Install with the flow arrow pointing toward your pool return. If you're experiencing intermittent chemical feeding or pump cycling issues, a failing check valve is often the culprit. This part prevents gravity siphoning that can drain chemical tanks and cause air locks in your system.

About Pentair Pool Products and Parts

Pentair is often considered the "gold standard" for pool professionals, and for good reason. Founded in 1966 (originally by five inventors making high-altitude balloons!), the company has evolved into the global leader in smart, sustainable water solutions. For the DIY homeowner, Pentair represents the intersection of rugged durability and silicon valley-tier technology. They pioneered the Variable Speed Pump revolution with the IntelliFlo®, saving American pool owners millions in energy costs. Today, their ecosystem focuses heavily on automation, allowing you to control your pump, heater, lights, and chemistry from a single app. While they are a favorite among professional builders, their "EC" (E-Commerce) line of equipment allows homeowners to access pro-grade technology with valid warranties for DIY installation.

Restoring Factory Performance with Genuine Pentair Parts

The "Pentair Parts" collection represents the dedicated Original Equipment Manufacturer (OEM) components required to maintain, repair, and extend the lifespan of your Pentair pool infrastructure. Unlike generic alternatives, these parts are engineered to the exact specifications of your original equipment—whether it be an IntelliFlo pump, MasterTemp heater, or Clean & Clear filter.

Buying genuine parts solves the critical issue of compatibility drift, where "universal" parts fail to seal correctly or communicate effectively with automation systems. This category encompasses everything from routine consumables (O-rings, pump baskets, filter cartridges) to critical core components (thermal regulators, control boards, and wet ends).

Homeowners and professionals choose this collection to ensure safety and warranty compliance. Using OEM parts guarantees that water flow dynamics, electrical loads, and gas line fittings remain within the safe operating limits designed by the factory. Whether you are fixing a minor leak or rebuilding a heater manifold, using the correct Pentair part is the only way to return your system to its "Day One" efficiency and reliability.

Common Questions +

Q: How do I ensure I am buying the correct part for my equipment?
A: Never rely solely on visual similarity. Locate the specific model number and serial number on your equipment's data plate (often a silver or white sticker on the side or inside the door). Cross-reference this with the "Exploded View" diagram for your specific model year to find the exact part number.

Q: Are these genuine Pentair parts or aftermarket replacements?
A: This collection features genuine OEM Pentair parts. While aftermarket options exist, OEM parts ensure exact fitment and material quality (such as chemical-resistant Viton seals) that generic parts often lack. Using genuine parts is often required to maintain your equipment's remaining warranty.

Q: Can I install these parts myself?
A: It depends on the "Class" of the repair. Routine maintenance parts like lid O-rings, baskets, and cartridges are designed for homeowner installation. However, parts involving high-voltage electricity (motors, boards) or gas lines (heater valves) should strictly be installed by a licensed professional to ensure safety and preventing catastrophic damage.

Q: Why does my part look different than the one I took off?
A: Manufacturers occasionally update parts to improve performance or durability. If the part number matches your equipment's current schematic, the new part is likely a "superseded" version that retrofits your unit. These updates often fix known issues from previous generations.

Q: What else do I need when replacing a part?
A: Almost all non-electrical repairs require a fresh application of pool-safe silicone lubricant (never petroleum jelly) on O-rings to create a water-tight seal. Additionally, if you are opening a pump or filter, it is best practice to replace the main housing gasket simultaneously to prevent new leaks.
