Product Details

The AquaLock 3540-10 CTS Union Check Valve is a reliable one-directional flow control valve designed for use with Copper Tube Size (CTS) tubing. Union-style construction allows for easy inline installation and removal without cutting or disturbing surrounding pipe runs, making it an ideal solution for both new installations and retrofit applications in plumbing and fluid distribution systems.

Check valves of this type are engineered to prevent backflow by allowing fluid to pass freely in one direction while automatically sealing against reverse flow. The union body design provides the added benefit of simple serviceability — the valve can be disconnected at either union end for inspection, cleaning, or replacement.

Key Features:

  • CTS (Copper Tube Size) compression-style union connections for tool-friendly installation
  • Integrated check valve mechanism prevents backflow and protects system components
  • Union body design enables easy inline installation, removal, and maintenance
  • Suitable for potable water, irrigation, and general plumbing applications
  • Durable construction designed for long-term performance in pressurized systems
  • Compact form factor fits in tight plumbing spaces

The AquaLock 3540-10 is a dependable choice for contractors and DIY plumbers seeking a straightforward, serviceable backflow prevention solution in CTS plumbing lines.

Have not had time to install, I will let you know how it turns out. Thanks

I ordered tires. Straight forward, easy, and affordable. How ordering tires should be.

Great pricing and super fast service!! Thank you!

Sp far so good thanks

Order was accurate and shipping was on time.

It's the information I needed for my boat motor. The only issue I had with this maintenance manual was the way the manual was finished. I've worked the the graphic arts industry for 50 years and am well versed in print finishing. The book will no doubt stay together, however there is excessive glue on the spine as the cover wraps around the front/back that distracts from the overall appearance.

Parts arrived in perfect condition. Installation went well. The on time and quick delivery was key to installation planning and

All good

These guys did a great job tires delivered two days before expected 2nd order from them both orders delivered in just a few days
