A. Determine the thickness of your wall. The faucet must pass through the exterior wall all the way through to the
interior of the wall to keep the inlet from freezing. Next, choose the style of inlet you will need to attach to the type of piping you are using. The
inlet length will be determined by the inlet type you choose. The inlet length is the length the faucet shaft is exposed on the interior wall to allow
your piping to be connected to the faucet. Order the faucet determined by the actual wall thickness of your wall, not the
overall length which includes the inlet length.
If your wall thickness is 4" then select the 4" wall thickness. If your wall is 4-1/2" thick then select the next size up to make sure the inlet
of the faucet goes through your wall so the inlet is protected from freezing conditions.
