How to use
To install the ARCO A-80 angle valve, first ensure the main water supply is turned off. Clean the pipe threads thoroughly to remove any debris. Apply appropriate thread sealant or PTFE tape to the male threads of the supply pipe. Screw the valve onto the pipe until it is securely tightened, ensuring the outlet is oriented correctly for your fixture. Once installed, connect the flexible hose from your fixture to the 3/8 inch outlet using the long nut. Gradually turn the water supply back on and check all connections for potential leaks.
What to consider before purchase
Verify the connection sizes of your existing pipes and fixtures
Ensure there is sufficient clearance for the long nut installation
Check local plumbing codes for compatibility requirements
Usage recommendations
