Compatibility & Installation Notes

Confirm the 18-inch insertion against the wall depth and supply layout before ordering. Install horizontally with the flange flush to a vertical wall and the spout downward, following PRIER’s drainage instructions. Keep the shutoff in a heated space, flush the supply before connection and use compatible press fittings and tooling. The self-draining function does not protect an incorrectly installed or obstructed hydrant.

Frequently Asked Questions

What is the inlet connection?

C-434Y18 has a 1/2-inch press-fit inlet. Use compatible fittings and press tooling.

Will it drain with a closed-end hose attached?

Yes. PRIER’s C-434 design drains after shutoff even with a closed-end hose attached, provided it is installed correctly.

What does the listed length mean?

18 inches is the nominal insertion length. Check the wall thickness and supply position to place the shutoff inside a heated area.

Is water draining behind the handle normal?

Brief drainage behind the packing nut after shutoff is part of the C-434 design. Persistent leakage should be inspected.

Why Buy from Big Frog Supply?

Choose C-434Y18 when the installation needs a 18-inch reach and 1/2-inch press-fit supply connection. Pairing those fit details with C-434’s hose-attached drainage helps you compare it with a standard wall hydrant before ordering.
