Prier® C-144D14 Diamond C-144 Freezeless Wall Hydrant with Anti-Siphon Vacuum Breaker

The Prier C-144 Diamond is the standard of quality for freezeless wall hydrants — satin nickel plated solid brass body, aluminum vacuum breaker cap, and dual backflow protection that meets ASSE 1019. It shuts off inside the heated wall, so the stem drains completely when you close it, leaving no water to freeze in the pipe. Prier has been manufacturing the C-144 since 1990, and every unit leaves the factory air-tested for leak-free quality.

The D14 is the 14" reach model — the longest standard stock size in the C-144 family, and the right choice for the thickest wall assemblies: full-depth concrete block, heavily insulated masonry, ICF (insulated concrete form) construction, or brick over block where the combined wall depth pushes past 12". If you've measured your wall at 13" to 14" from the interior supply connection to the outside face, this is your hydrant. For walls exceeding 14", Prier manufactures the C-144 in lengths up to 24" on request — call us and we can source the right reach.

How to choose the right length: Wall hydrant length = the distance from your interior supply connection point to the outside face of the wall. Measure through every layer — block, insulation, brick, mortar, cladding — before ordering. The valve seat must sit inside the heated space, not within the wall assembly.
