Arrowhead Brass 462 Series Hydrant Length Guide

The wall thickness is the measurement from the front of the wall to where the faucet connects to the plumbing.

Keep in mind that the fitting (1/2” Uponor PEX A) will add 1 3/4" to the overall length of the hydrant.

If you already have a faucet, you can measure from the wall plate back to where the fitting starts to get the wall thickness like the diagram below.
