PLUMBING CODES

Simple plumbing jobs such as replacing a washer in a faucet or un-clogging a sink can be done by yourself, but you may find you need a permit or license for large jobs like adding a new bathroom or kitchen. Check with your local municipality.

THE TWO SYSTEM APPROACH

There are two systems involved in home plumbing, the water supply and the drain/vent system (DWV). The smaller pipes carry the supply and the larger ones the drain vent DWV. Vents allow the gasses to escape and balance the air pressure in the system.

METAL PIPES

Copper and galvanized pipes are used for water lines, nongalvanized black pipe is used for gas lines only. Threaded pipe is measured by its inside diameter such as 1/2 inch or 3/4 inch. When replacing a length of galvanized pipe always allow for overlap at the joints. Add a half inch per joint. For larger pipe diameters like inch and a half add 5/8 inch per joint.

PLASTIC PIPES

PVC type plastic pipe is used for cold water supply and CPVC is used for hot. ABS pipe is used for drains and vents. Don't try to glue two different types together. There is a glue for each type of plastic pipe.

LEAK CONTROL

A temporary fix for a leaking PVC drain pipe fitting is to place a automobile type radiator hose clamp around the fitting.

ELECTRICIAN'S CODE

The National Electric Code, the NEC, defines a set of rules for safe electrical installation. These codes are revised every three years and the local codes follow the NEC but they are usually more stringent. In many cases you are allowed to install new circuits up to the service entrance box if a licensed electrician inspects your work and then completes the hookup. In other areas local codes require all work to be done by licensed electricians. Contact your local building department for requirments before you begin.

GFI's

A ground fault interrupter or GFI is a type of power outlet that can protect you from electrical shock if you become part of the electric circuit. These outlets should be installed in bathrooms, kitchens, wash rooms and anywhere you and electricity could come into contact with moisture. They can save a life. GFI outlets should be tested monthy by pushing the small red button that says "test" then the reset button. This is something every home or cabin should not be without.

PULLING WIRES

Here is a neat trick for pulling new wires through conduit. Measure and cut a piece of yarn about a foot or two longer than the conduit. Then hook up a vacuum cleaner hose to the far end of the conduit and turn on the vacuum. The yarn will be sucked through the pipe and you can use it to pull the wire through.
