Installing a new hose bib so your hose will reach your garden?  Your existing wall faucet reach the end of its useful life?  Here is some Home Maintenance perspective for your wall mounted faucets on all sides of your Home and Garden.

When installing a new hose bib, the plumbing code now requires the use of a frost free sillcock.

Which, in theory will not freeze, split and cause all kinds of water damage and mayhem.

Traditionally, the homeowner had to remember to shut off the supply to the outside water faucet (alternately known as a wall mounted faucet, wall hydrant), with the changing of the seasons -or else it would freeze and usually split the supply line.  With that old design the water supply was right there at the shut off -fully exposed to the elements.  It could -and did easily freeze if the supply was not shut off inside the house -usually requiring the replacement of a section of copper pipe and a big clean-up effort.

The new design has the actual valve inside the wall at the end of a long stem.  So, if there is residual water in the stem that freezes, it is downstream from the valve and will not result in a break in the supply line.

Here is a plumbing tip you may -or, may not find in your handy “How to do Plumbing” handbook:

There is a caveat that goes along with the ‘freeze proof’ faucet.  It is freeze proof or frost free only if installed properly -that is, with a slight downward pitch.  If it is installed without pitch, there will be residual water in the stem that will freeze. The stem will split.  You won’t know it until the water is turned back on in the spring.  It will leak only when it is in use (i.e. when you use your hose).  It may even go unnoticed for a time as the leak will be inside the wall or inside the building.  So, the frost free spigot is a misnomer.  It can freeze.

The general recommendation for the autumn is to shut off the supply to the outdoor spigots, open the valve slightly and leave it open.  Disconnect and drain all hoses to prevent their freezing, as well.
