Let’s Talk About Watts Aqualock Check Valve Union 1/2in.CTS
The Watts Aqualock Check Valve Union 1/2in.CTS is a seemingly simple component, yet it can play a critical role in plumbing systems, preventing backflow and ensuring clean water delivery. The Watts brand is known for its reliability in plumbing components, and this check valve union promises a quick and easy installation. This is thanks to its push-to-connect design.
My own journey to needing this check valve stemmed from a frustrating experience with a backflow issue in my well water system. A recent plumbing modification to add an irrigation line created a potential back-siphonage point. This meant that fertilizer-contaminated irrigation water could potentially flow back into my potable water supply. I wanted to ensure my family’s water safety, so a reliable check valve was non-negotiable.
Upon receiving the Watts Aqualock Check Valve Union 1/2in.CTS, I was immediately impressed by its solid feel. The off-white Polysulfone construction appeared robust and durable, unlike some cheaper plastic fittings I’ve handled. Its lightweight design also suggested ease of handling and minimal impact on the existing plumbing.
Compared to standard threaded check valves or even compression fittings, the Aqualock system stood out due to its promised tool-free installation. I considered using a brass check valve, like those from Apollo, but installation required threading and sealing, adding extra steps. I also looked at SharkBite push-to-connect options, but chose Watts due to the reputation for chemical resistance in well water applications. The Watts option seemed the fastest and most reliable solution for preventing backflow.
My initial impression was a blend of excitement and cautious optimism. The tool-free promise was appealing, but the ultimate test would be its leak-proof performance under pressure. I was eager to see if the Watts Aqualock Check Valve Union 1/2in.CTS would live up to its reputation and solve my backflow concerns.
Real-World Testing: Putting Watts Aqualock Check Valve Union 1/2in.CTS to the Test
First Use Experience
I installed the Watts Aqualock Check Valve Union 1/2in.CTS directly into my existing 1/2″ copper piping in the well system. This was installed between the main water line and the new irrigation takeoff. The installation process was surprisingly straightforward: cut the copper pipe, ensure it was clean and deburred, then simply push the valve onto the pipe. No tools were needed and within minutes, the valve was in place.
I tested the system under normal well pump pressure (around 50 PSI). I carefully inspected the connections for leaks. To simulate backflow, I deliberately created negative pressure on the downstream side of the valve. There were no leaks. The check valve effectively prevented any water from flowing back towards the well.
The ease of use was a major plus. Unlike threaded connections that require careful tightening and pipe dope, the Watts Aqualock system simplified the process significantly. I did note that ensuring the pipe was perfectly straight and deburred was crucial for a secure, leak-free connection.
Extended Use & Reliability
After several months of use, the Watts Aqualock Check Valve Union 1/2in.CTS has performed flawlessly. It’s been subjected to fluctuating water pressures and temperatures. I’ve seen no signs of leaks or degradation.
The Polysulfone material seems highly resistant to the chemicals present in my well water, including iron and manganese. There’s no visible corrosion or discoloration. Minimal maintenance has been required. I occasionally inspect the valve for debris buildup, but so far, it’s remained clean and unobstructed.
Compared to previous experiences with cheaper check valves that often failed after a short period, the Watts Aqualock has been a significant upgrade. The Watts valve has given me peace of mind. It consistently performs its intended function, preventing backflow and protecting my water supply.
