Wall Faucet Installation
Installation Guide

Proper Installation Prevents Freezing

A frost-proof wall faucet only works correctly when installed with a slight downward pitch. This allows the faucet barrel to drain after every use, helping prevent trapped water, freezing, and burst pipes.

Proper installation diagram for Merrill frost-proof wall faucet showing downward pitch.
Installation Tip: The inlet must be slightly higher than the faucet outlet so the barrel drains completely after the water is turned off. A level or upward installation from inlet to outlet wall trap water inside the faucet and increase the risk of freeze damage.

★★★★ Keeps your pipes from bursting
Reviewed in the United States on September 29, 2022

This is what you need for your outside hose bibb if you live in an area that freezes. It will help keep your pipes from bursting. It is self-draining and has an anti-siphon device on the top. It is full turn, not a ball valve. The end connection is a 1/2-inch PEX connection. The 10-inch length should get you through most outside walls unless you have something very thick.

Wall Faucet, Hose Bibb, and Sillcock FAQs
Wall Faucet Guide

Common Questions

Will this frost-proof wall faucet keep my pipes from freezing?

Yes. It is a frost-free, self-draining sillcock built to help prevent frozen pipes and burst faucets during winter when installed with the required downward pitch.

Does this hose bibb have anti-siphon protection?

Yes. The Merrill MA Series anti-siphon outdoor faucet uses dual air checks for backflow protection, helping prevent contaminated hose water from entering potable water lines.

Will this wall faucet fit my wall thickness and plumbing?

Merrill MA Series wall faucets are available in multiple lengths from 4 inches to 14 inches. MIP, copper-sweat, and FIP connection options are available to fit common wall constructions and plumbing configurations.

Is this wall faucet built to last?

Yes. Merrill wall faucets use low-lead brass, chrome-plated finishes, stainless-steel hardware, and modern rubber packing to provide a durable, leak-resistant outdoor water connection.

How do I install a sillcock so it drains properly?

Install the wall faucet with the inlet positioned higher than the outlet so the faucet body slopes downward toward the spout. Avoid attaching shutoff valves or other devices to the hose end that could prevent the sillcock from draining.
