Questions about this item

What pipe size and thread type must my supply lines have to connect to this valve's FNPT ports?

The valve uses 1 1/4 in FNPT connections, so your supply lines need matching male NPT threads in that size.

Will the lead-free bronze body withstand the 180 °F upper limit of my existing water heater?

Yes, the assembly is rated for a maximum temperature of 180 °F, matching standard residential water-heater output.

How can I verify the double-check mechanism is holding pressure after installation?

Pressurise the line to the 175 psi working limit and confirm no pressure drop on the downstream gauge.
