Outdoor Spigot Types


Generally, a tap is also called a spigot or faucet valve for regulating the flow of liquid or gas. The term “Spigot” or “Faucet” is more commonly used to refer to the control valves installed in the water lines. Outdoor spigots provide homeowners a lot of convenience for their outdoor gardening for watering plants, entertaining, rinsing and cleaning of food, cleaning of exteriors and other activities that require water.

The water to the outdoor spigot comes from an existing pipeline from inside the house from the main water line. It mainly uses cold water. A standard outdoor hose faucet freezes in the extreme cold weather as the spigot is outside the heated house. This exposes the water below freezing point.  As the temperature falls below the freezing point of water, the water in the faucet and the exposed pipe freezes into ice and expands causing the bursting of the pipe. The plumbing inside house is insulated or heated for protection. The normal outdoor spigot is therefore susceptible to damage by severe weather.

Therefore, you need a freeze proof outdoor spigot. They are between 4 and 24 inches in length and extend back into the house. There valve seat is inside the house. When you turn off the spigot, the water is stopped all the way inside only and it cannot go out to the colder portion of the faucet. It remains in the pipe that is warm inside the home. Any small quantity of the water beyond the valve on outer side is drained out of the spigot and there is no chance of its bursting.

There are mainly three types of outdoor spigots namely, sill faucets, hose bib faucets and the boiler drain faucets. Each of these spigots performs a specific function in different weather.

Sill Faucet:

This is also commonly called a sill cock. It has hose threads on its spout. There is a flange on it that mounts this spigot flush against an external wall. The spigot is generally inclined at 45  degrees downwards. The sill faucet comprises of a 6 to 12 inch horizontal pipe that goes into the wall. The spigot valve is located at the end of its pipe that goes into the wall. The valve regulates the flow of water to outside. The sill faucet is designed in such a manner the handle of faucet remains outside the house.  The valve mechanism stays inside the insulated house away from outside parts. Thus, there is no chance of the water being exposed or frozen to block or burst the pipe.

Hose Bib Spigot:

The hose bib spigot, is one of the most commonly used outdoor faucet and many people call it as a spigot. This outdoor spigot is almost similar in appearance to a sill faucet with its hose threads on its spout 45 degrees angled downward. In a hose bib, faucet water flow valve is just under its control handle. Due to this design, the valve remains exposed to the outside freezing conditions making it vulnerable to freezing in cold climate. As such, it is not a freeze proof-outdoor spigot.

Boiler Drain Valves:

This spigot was originally designed as a drain valve for the boiler. Its name is still unchanged. Boiler drain valve can be installed at the end of a horizontal or vertical pipe. The spout is fitted at 90 degrees angle to the water pipeline. This valve also has spout with hose threads. Generally, the spigot is connected to a washing machine with a flexible hose.

The outdoor spigot is repairable using only replaceable factory parts.
