Installation Tips:

1. Choose the Right Location
Install the backflow preventer in a horizontal position, ideally close to the water service entry point. Ensure it’s installed above ground and never in a location subject to freezing.

2. Provide Proper Clearance
Allow enough space around the unit for testing, maintenance, and repairs. Minimum clearance should be maintained above and around the assembly for tool access and drainage.

3. Use Approved Drainage
Since the relief valve may discharge water, connect an approved air gap drain fitting to direct any discharge safely away. This helps prevent flooding and meets plumbing code requirements.

4. Confirm Flow Direction
Install with flow direction matching the arrows marked on the valve body. Misalignment can compromise system safety and void compliance.

5. Test After Installation
After installation, perform a backflow test using the top-mounted test cocks. Professional testing ensures the assembly meets local backflow prevention codes and confirms functional integrity.

6. Check for Freeze Protection
If installing outdoors, protect the unit with an insulated WattsBox enclosure to prevent damage from freezing temperatures.

7. Secure Mounting
Use proper bracketing or supports for piping to reduce strain on the assembly and avoid misalignment during operation.

8. Don’t Skip Permits
Always check with your local water authority and building codes. Some jurisdictions require permits and certified professional installation for backflow preventers.
