Double Check Valve Assembly 1 In

The Apollo 4ALF105A2F is a double check valve assembly designed for plumbing systems that require backflow prevention. It fits installations calling for a 1-inch FNPT connection and lead-free bronze construction.

Questions about this item

What does the FNPT connection on this 1-inch double check valve mean for pipe threading?

The FNPT connection means the valve has female National Pipe Taper threads, so it accepts a 1-inch male NPT pipe end directly without a separate adapter.

How much straight pipe run does the 14-5/8 inch body length require for installation?

You need at least 14-5/8 inches of clear straight pipe run to accommodate the valve body, plus extra length for the threaded pipe ends that screw into each FNPT port.

What is the correct flow direction when installing this Apollo 4ALF-100 series valve?

Install the valve so the flow arrow cast on the lead-free bronze body points in the direction water travels through the line; reversing it prevents the check modules from opening properly.
