My Buying Guide on Pool Non Return Valve
When I first started setting up my swimming pool, I quickly learned that a pool non-return valve is an essential component for maintaining proper water flow and preventing backflow. If you’re considering adding one to your pool system, I’ve put together this buying guide based on my experience to help you make an informed decision.
What is a Pool Non Return Valve?
A pool non-return valve, also known as a check valve, is designed to allow water to flow in one direction only. This feature is crucial for preventing water from flowing back into the pump or filter system, which can lead to inefficiencies and potential damage. Understanding how this valve works and its importance has been a game-changer for my pool maintenance routine.
Why Do I Need a Non Return Valve?
In my experience, a non-return valve is vital for several reasons:
- Preventing Backflow: I found that without this valve, water could flow backward, causing issues with my filtration system and leading to potential contamination.
- Maintaining Pressure: The valve helps maintain proper pressure in the system, which is essential for effective filtration and circulation.
- Protecting Equipment: It offers protection for my pump and other equipment, extending their lifespan and saving me money on repairs.
Types of Non Return Valves
When I was shopping for a non-return valve, I discovered that there are several types to choose from. Here are the main ones I’ve come across:
- Swing Check Valves: These are commonly used in pool systems. They feature a hinged disc that swings open to allow water flow and closes to prevent backflow. I’ve found them reliable and efficient.
- Spring Check Valves: These use a spring mechanism to close the valve when water flow stops. I appreciated their quick response time, which can be beneficial in certain setups.
- Dual-Disc Check Valves: These have two discs that open and close with the flow of water. I liked these for their low-pressure drop and compact design, making them suitable for tighter spaces.
Factors to Consider When Buying
Here are some key factors I considered when purchasing my non-return valve:
- Size and Compatibility: I ensured that the valve matched the size of my pipes and was compatible with my existing pool equipment. It’s crucial to measure correctly to avoid leaks.
- Material: Non-return valves are typically made from plastic, brass, or PVC. I opted for a durable material that could withstand the chemicals in pool water and resist corrosion.
- Flow Rate: I looked for a valve that could handle my pool’s specific flow rate to ensure optimal performance. Checking the manufacturer’s specifications helped me make an informed choice.
- Ease of Installation: I appreciated valves that were easy to install. Some come with clear instructions or pre-installed fittings, which made my job much easier.
Price Range
In my search for a non-return valve, I found a wide price range depending on the brand, material, and features. Typically, I saw prices ranging from $20 to $100. I recommend setting a budget but also considering that investing in a quality valve can save money in the long run by preventing costly repairs.

I found that non-return valves are available at various places, including:
- Local Pool Supply Stores: These often have knowledgeable staff who can help with my questions.
- Online Retailers: Websites like Amazon and specialty pool retailers offered a wider selection and competitive prices, which I found convenient.
