My Buying Guides on Pool Non Return Valve
When I first started looking for a pool non return valve, I quickly realized there’s more to it than just picking any valve off the shelf. To help you avoid the confusion I went through, here’s my straightforward guide based on my own experience.
What Is a Pool Non Return Valve?
A pool non return valve, sometimes called a check valve, is a device that allows water to flow in only one direction. This is crucial for preventing backflow, which can cause contamination or damage to your pool pump and plumbing.
Why I Needed One
In my case, the non return valve was essential to stop water from draining back into the pool pump when it was turned off. Without it, the pump had to work harder and sometimes got damaged. If you want to protect your equipment and maintain water quality, this valve is a must-have.
Key Features I Looked For
- Material: I chose a valve made of durable, corrosion-resistant material like PVC or stainless steel since it’s constantly exposed to water and pool chemicals.
- Size Compatibility: It’s important to get the right size to fit your existing pipes. I measured my pipe diameter carefully before buying.
- Flow Direction Indicator: Most valves have an arrow showing the flow direction. This helped me install it correctly the first time.
- Easy Installation: I preferred a valve that was easy to install without specialized tools or professional help. Threaded or slip-on connections made this simpler.
- Pressure Rating: I checked the pressure rating to ensure the valve could handle my pool’s water pressure without leaking or failing.
Types of Pool Non Return Valves I Considered
- Swing Check Valve: Simple design and good for moderate flow rates. I liked that it had fewer moving parts, so less maintenance.
- Spring Check Valve: Offers quicker closing action, which helps prevent water hammer. This was important for my pool system to avoid pipe damage.
- Ball Check Valve: Compact and reliable, but sometimes not suitable for larger pipe sizes.
Installation Tips from My Experience
- Always install the valve in the correct flow direction—look for the arrow on the valve body.
- Make sure the valve is accessible for future maintenance or replacement.
- Use Teflon tape or appropriate sealant on threaded connections to prevent leaks.
- Test the system after installation to check for proper operation and any leaks.
Maintenance and Troubleshooting
From my experience, regular inspection is key. I checked the valve periodically for debris or wear that could cause it to stick open or closed. If you notice water flowing backward or strange noises in your system, the valve might need cleaning or replacement.
Final Thoughts
Buying a pool non return valve might seem straightforward, but getting the right one for your system makes a big difference. By focusing on quality, size, and ease of installation, I was able to protect my pool equipment and enjoy worry-free swimming. I hope my guide helps you choose the perfect valve for your pool setup!
